Errno 13 permission denied python ошибка

If we provide a folder path instead of a file path while reading file or if Python does not have the required permission to perform file operations(open, read, write), you will encounter PermissionError: [Errno 13] Permission denied error

In this article, we will look at what PermissionError: [Errno 13] Permission denied error means and how to resolve this error with examples.

We get this error mainly while performing file operations such as read, write, rename files etc. 

There are three main reasons behind the permission denied error. 

1. Insufficient privileges on the file or for Python
2. Passing a folder instead of file
3. File is already open by other process

How to Fix PermissionError: [Errno 13] Permission denied error?

Let us try to reproduce the “errno 13 permission denied” with the above scenarios and see how to fix them with examples.

Case 1: Insufficient privileges on the file or for Python

Let’s say you have a local CSV file, and it has sensitive information which needs to be protected. You can modify the file permission and ensure that it will be readable only by you.

Now let’s create a Python program to read the file and print its content. 

# Program to read the entire file (absolute path) using read() function
file = open("python.txt", "r")
content = file.read()
print(content)
file.close()

Output

Traceback (most recent call last):
  File "C:/Projects/Tryouts/python.txt", line 2, in <module>
    file = open("python.txt", "r")
PermissionError: [Errno 13] Permission denied: 'python.txt'

When we run the code, we have got  PermissionError: [Errno 13] Permission denied error because the root user creates the file. We are not executing the script in an elevated mode(admin/root).

In windows, we can fix this error by opening the command prompt in administrator mode and executing the Python script to fix the error. The same fix even applies if you are getting “permissionerror winerror 5 access is denied” error

In the case of Linux the issue we can use the sudo command to run the script as a root user.

Alternatively, you can also check the file permission by running the following command.

ls -la

# output
-rw-rw-rw-  1 root  srinivas  46 Jan  29 03:42 python.txt

In the above example, the root user owns the file, and we don’t run Python as a root user, so Python cannot read the file.

We can fix the issue by changing the permission either to a particular user or everyone. Let’s make the file readable and executable by everyone by executing the following command.

chmod 755 python.txt

We can also give permission to specific users instead of making it readable to everyone. We can do this by running the following command.

chown srinivas:admin python.txt

When we run our code back after setting the right permissions, you will get the following output.

Case 2: Providing the file path

In the below example, we have given a folder path instead of a valid file path, and the Python interpreter will raise errno 13 permission denied error.

# Program to read the entire file (absolute path) using read() function
file = open("C:\Projects\Python\Docs", "r")
content = file.read()
print(content)
file.close()

Output

Traceback (most recent call last):
  File "c:PersonalIJSCodeprogram.py", line 2, in <module>
    file = open("C:\Projects\Python\Docs", "r")
PermissionError: [Errno 13] Permission denied: 'C:\Projects\Python\Docs'

We can fix the error by providing the valid file path, and in case we accept the file path dynamically, we can change our code to ensure if the given file path is a valid file and then process it.

# Program to read the entire file (absolute path) using read() function
file = open("C:\Projects\Python\Docspython.txt", "r")
content = file.read()
print(content)
file.close()

Output

Dear User,

Welcome to Python Tutorial

Have a great learning !!!

Cheers

Case 3: Ensure file is Closed

While performing file operations in Python, we forget to close the file, and it remains in open mode.

Next time, when we access the file, we will get permission denied error as it’s already in use by the other process, and we did not close the file.

We can fix this error by ensuring by closing a file after performing an i/o operation on the file. You can read the following articles to find out how to read files in Python and how to write files in Python.

Conclusion

In Python, If we provide a folder path instead of a file path while reading a file or if the Python does not have the required permission to perform file operations(open, read, write), you will encounter PermissionError: [Errno 13] Permission denied error.

We can solve this error by Providing the right permissions to the file using chown or chmod commands and also ensuring Python is running in the elevated mode permission.

Python is a program designed for building websites, software, and more using a high-level programming language. However, users have recently reported receiving a permission denied error in Windows 11. Here’s how to fix PermissionError [Errno 13] Permission denied error in Python.

Because Python uses a general-purpose language, it can be used to build a variety of different types of programs rather than focusing on a specific variable.

For those wanting to learn more about developing and coding, Python is one of the easiest programming languages to learn, making it perfect for beginners.

Why do I get the permission denied error in Python?

Users encounter PermissionError: [Errno 13] Permission denied error if providing Python with a file path that does not have permission to open or edit the file. By default, some files do not allow certain permissions. This error may also occur if providing a folder rather than a file.

If the file is already being operated by another process, then you may encounter the permission denied error in Python. If you’re receiving the Python runtime error, we offer solutions for that as well.

How do I fix the Python permission denied error in Windows 11?

1. Check file path

One of the main causes of PermissionError: [Errno 13] Permission denied is because Python is trying to open a folder as a file. Double-check the location of where you want to open the file and ensure there isn’t a folder that exists with the same name.

Run the os.path.isfile(filename) command replacing filename with your file to check if it exists. If the response is false, then the file does not exist or Python cannot locate it.

2. Allow permissions using chomd

If the file does not have read and write permissions enabled for everyone, then you may encounter the permission denied error in Python. Try entering the chomd 755 filename command and replace filename with the name of your file.

This command gives everyone permission to read, write, and execute the file, including the owner. Users can also apply this command to entire directories. Running the ls -al command will provide a list of files and directories and their permissions.

3. Adjust file permissions

1. Navigate to the location of your file in file explorer.
2. Right-click on the file and select Properties.
3. Click the Security tab then select your name under Group or user names.
4. Select Edit and go through and check permissions.
5. Click Apply then OK.

Adjusting the permissions of the file that you’re trying to open will allow Python to read, write, and execute the file.

4. Turn off execution aliases

1. Click on Start and open Settings (or press Windows + I).
2. Open Apps then select Apps & features.
3. Open the drop-down menu next to More settings.
4. Click App execution aliases.
5. Locate the two App Installers for python.exe and python3.exe and toggle both to Off.

Python was added to the Microsoft Store for version 3.7 which introduced permission denied errors because it created two installers: python.exe and python3.exe. Disabling the Microsoft Store versions of Python should fix the permissions denied error.

5. Update Windows and drivers

1. Click on Start and open Settings (or press Windows + I).
2. Scroll down and select Windows Update.
3. Perform any available updates.
4. Select Advanced options.
5. Under Additional options, click on Optional updates.
6. Run any driver updates.

If you’re suddenly encountering the Python permission denied error and none of the above solutions worked, then check for any Windows 11 updates and perform any available driver updates.

If this method didn’t work either, we recommend you use specialized driver update software, DriverFix.

DriverFix is a fast and automated solution for finding all outdated drivers and updating them to their latest versions. The installation process it’s fast and safe so no additional issues will occur.

What is the latest version of Python?

As of the release of this article, the latest version of Python is 3.10.7 which is available for Windows 8 and newer and is not compatible with older versions including Windows 7. Python supports Windows, macOS, Linux/UNIX, and more.

However, If users want to use older versions of Python, they can access releases 2.7 and newer or they can download a specific version of a release.

If you want a quick way to open PY files on Windows 10 and 11, we offer a guide for that as well.

Hopefully, one of the above solutions helped you fix the Python permission denied error in Windows 11. Let us know in the comments which step worked for you or if you have any suggestions for a different solution.

Permission denied means you are not allowed to access a file. But why this happens? This is because a file has 3 access properties – read, write, and execute. And 3 sets of users – owner, group, and others. In this article we will look at different solutions to resolve PermissionError: [Errno 13] Permission denied.

What is permission denied error?

Suppose you have a file in your computer but you can’t open it. Strangely another user can open the same file. This is because you don’t have permission to read the content of that file.

Permission denied on files to protect them. For example, you have stored username & password for your database in a file so you never want it to be accessible to anyone except the database application and you. That’s why you will restrict it from other applications, software, processes, users, APIs etc.

In a system, root user can access everything. So, we seldom use the root account otherwise there is no meaning of security. A software running with root privilege can access your password file which you wanted to be secure. That’s why sudo should be used with caution.

How these permissions are defined?

There are 3 types of permissions – read, write and execute. With read permission a software, process, application, user etc. can read a file. Similarly, with write permission they can write to the file. Execute is used to run it.

Now the question is, how to apply these permissions to different software, users etc.? Well there are 3 types of users – owner, group, and others. So, you can assign 3 sets of permissions, like this –

Let’s get back to our password file example. Now you are into others user category because you are not the owner of the file and probably not the part of group. People use to give least permissions to the others because these are the access levels for everyone.

The password file won’t have any permission in others category. And trying to access that will result in permission error: permission denied.

Reasons of permissionerror ERRNO 13 in Python

Primarily these are the reasons of permissionerror: errno13 permission denied in Python –

1. Using folder path instead of file path while opening a file.
2. Trying to write to a file which is a folder.
3. Trying to write to a file which is already opened in an application.
4. File permission not allowing python to access it.
5. File is hidden with hidden attribute.

Let’s understand each of these reasons one by one and check their solutions.

Using folder path instead of file path while opening a file

To open a file for reading or writing, you need to provide the absolute or relative path to the file in open function. Sometimes we create path of parent folder instead of file and that will lead to the permission error 13. Check out this code –

file = open("C:\users\akash\Python\Documents", "r")
file.close()

The output will be –

Traceback (most recent call last):
  File "jdoodle.py", line 2, in <module>
    file = open("C:\users\akash\Python\Documents", "r")
PermissionError: [Errno 13] Permission denied: 'C:\users\akash\Python\Documents'

The reason for the error in above code is that we have used C:usersakashPythonDocuments as path which is a directory. Instead we needed to use C:usersakashPythonDocuments\myFile.csv.

Trying to write to a file which is a folder

This is a common case. Suppose you want to write to a file using Python but a folder with same name exists at that location then Python will get confused and try to write to a folder. This is not a right behavior because folders are not files and you can’t write anything on them. They are used for holding files only.

Trying to write to a file which is a folder will lead to permission error errno 13. Check this code –

# Directory Structure
# 📂/
# |_ 📂Users
#    |_ 📁myFile

file = open("/Users/myFile", "w")
file.write("hello")
file.close()

The output will be –

Traceback (most recent call last):
  File "jdoodle.py", line 2, in <module>
    file = open("/Users/myFile", "r")
PermissionError: [Errno 13] Permission denied: '/Users/myFile'

In the above example we showed the directory structure and tried to write to myFile. But myFile is already a name of directory in the path. Generally, if a file doesn’t exist and we try to write to it then Python creates the file for us. But in this case there is already a directory with the provided name and Python will pick it. This will lead to permission error.

The solution to this problem is to either delete the conflicting directory or use a different file name.

Trying to write to a file which is already opened in an application

If a file is already opened in an application then a lock is added to it so that no other application an make changes to it. It depends on the applications whether they want to lock those files or not.

If you try to write to those files or more, replace, delete them then you will get permission denied error.

This is very common in PyInstaller if you open a command prompt or file explorer inside the dist folder, then try to rebuild your program. PyInstaller wants to replace the contents of dist but it’s already open in your prompt/explorer.

The solution to this problem is to close all the instances of applications where the file is opened.

File permission not allowing python to access it

In the above section we talked about file permissions. Python will be in others category if it is not set as user or in a group. If the file has restrictive permissions for others then Python won’t be able to access it.

Suppose the permission to the file is –

Owner – read, write, execute
Group – read, write
Others – none

Then only owner and group will be able to read and write to the file. Others will not be able to access it. Check out this image –

In this image the file owner is www, group is www, owner permissions are read+write, group permission is read only, while others have no permissions.

The solution to this problem is to either provide appropriate permission to the file for others, or add Python as owner or to the group.

Another solution is to run Python with root privilege.

File is hidden with hidden attribute

If your file is hidden then python will raise permission error. You can use subprocess.check_call() function to hide/unhide files. Check this code –

import subprocess

myPath = "/Users/myFile.txt"
subprocess.check_call(["attrib", "-H", myPath])

file_ = open(myPath, "w")

In the above code -H attribute is used to unhide the file. You an use +H to hide it again.
