Permissionerror errno 13 permission denied python linux

Python PermissionError: [errno 13] permission denied Solution

Python can only open, read from, and write to files if an interpreter has the necessary permissions. If you try to open, read from, or write to a file over which Python has no permissions, you’ll encounter the PermissionError: [errno 13] permission denied error.

In this guide, we discuss what this error means and why it is raised. We’ll walk through an example so you can learn exactly how to solve this error.

PermissionError: [errno 13] permission denied

Computers use file permissions to protect the integrity of files. Some files have restricted access by default. You can change the access permissions of a file at any time.

Let’s say you are working on an important program. You may only want that program to be readable by you. To accomplish this, you could modify the “read” permissions on all the files and folders in your program. This would limit access to your program.

Any file that you try to access from a Python program must be readable by the user or group that is running the file.

If you are running a Python script from a web server process, for instance, you would need to make sure that the user that owns the web server has access to all the files that you reference in your code.

An Example Scenario

We’re going to build a program that reads a list of NFL scores from a file into a program.

We have a file called afc_east.csv which contains the following:

Our file is a CSV. We’re going to import the Python csv module into our code so we can work with the file:

Next, let’s open up our file in our Python program. We can do this using the csv.reader() statement:

This code will open up the file called afc_east.csv in read mode. Then, the CSV reader will interpret the file. The CSV reader will return a list of values over which we can iterate. We then print each of these values to the console using a for loop and a print() statement so we can see the contents of our file line-by-line.

Let’s run our program to see if it works:

Our code returns an error.

The Solution

A PermissionError indicates that Python does not have the right permissions to access a file.

Let’s check the permissions of our file. We can do this using the ls -la command:

We can see that the afc_east.csv file is owned by the root user:

This is a problem because we don’t run Python as root. This means that Python cannot read our file. To fix this error, we need to change the ownership permissions of our file using the chown command:

This command makes the “james” user and the “admin” group the owners of the file.

Alternatively, we could change the permissions of the file using the chmod command:

This command makes our file readable and executable by everyone. The file is only writable by the owner. Let’s try to run our Python script again:

Our code successfully prints out all of the scores from our file.

Conclusion

The PermissionError: [errno 13] permission denied error occurs when you try to access a file from Python without having the necessary permissions.

To fix this error, use the chmod or chown command to change the permissions of the file so that the right user and/or group can access the file. Now you have the skills you need to solve this error like a pro!

PermissionError: [Errno 13] in Python

Just starting to learn some Python and I’m having an issue as stated below:

Seems to be a file permission error, if any one can shine some light it would be greatly appreciated.

NOTE: not sure how Python and Windows files work but I’m logged in to Windows as Admin and the folder has admin permissions.

I have tried changing .exe properties to run as Admin.

. you’re trying to open a directory as a file, which may (and on most non UNIX file systems will) fail.

Your other example though;

should work well if you just have the permission on a.txt . You may want to use a raw ( r -prefixed) string though, to make sure your path does not contain any escape characters like \n that will be translated to special characters.

For me, I was writing to a file that is opened in Excel.

For me, I got this error when I was trying to write a file to a folder and wanted to make sure the folder existed. I accidentally used:

but the second line means «make a directory at this exact path (and make its parents too, without throwing errors for them existing already)». The third line then throws a PermissionError , because you can’t use open() on a directory path, of course! The second line should have been:

I encountered this problem when I accidentally tried running my python module through the command prompt while my working directory was C:\Windows\System32 instead of the usual directory from which I run my python module

Errno 13 Permission denied Python

In python, I am currently experimenting with what I can do with open command. I tried to open a file, and got an error message. Here’s my code:

My error message was:

I looked on the website to try and find some answers and I saw a post where somebody mentioned chmod . 1. I’m not sure what this is and 2. I don’t know how to use it, and thats why I’ve come here.

For future searchers, if none of the above worked, for me, python was trying to open a folder as a file.

Check at the location where you try to open the file, if you have a folder with exactly the same name as the file you try to open (the file extension is part of the file name).

Your user don’t have the right permissions to read the file, since you used open() without specifying a mode.

Since you’re using Windows, you should read a little more about File and Folder Permissions.

Also, if you want to play with your file permissions, you should right-click it, choose Properties and select Security tab.

Or if you want to be a little more hardcore, you can run your script as admin.

SO Related Questions:

If nothing worked for you, make sure the file is not open in another program. I was trying to import an xlsx file and Excel was blocking me from doing so.

The problem here is your user doesn’t have proper rights/permissions to open the file this means that you’d need to grant some administrative privileges to your python ide before you run that command.

As you are a windows user you just need to right click on python ide => select option ‘Run as Administrator’ and then run your command.

And if you are using the command line to run the codes, do the same open the command prompt with admin rights. Hope it helps

If you have this problem in Windows 10, and you know you have premisions on folder (You could write before but it just started to print exception PermissionError recently).. You will need to install Windows updates. I hope someone will help this info.

python bind socket.error: [Errno 13] Permission denied

I have a python script which gets packets from a remote machine and writes them (os.write(self.tun_fd.fileno(), ».join(packet))) to a tun interface gr3:

I would like to receive those packets via a separate pong script as follows:

You can’t bind to port numbers lower than 1024 as a unprivileged user.

So you should either:

• Use a port number larger than 1024 (recommended)
• Or run the script as a privileged user

Harder, but more secure solution if it’s really necessary to accept from 111:

• Run the as unprivileged on a higher port, and forward port 111 to it externally.

Although not in the original question, just want to expand this to the case of unix sockets for local interprocess communication, i.e. AF_UNIX . As seen in man unix 7 :

In the Linux implementation, pathname sockets honor the permissions of the directory they are in. Creation of a new socket fails if the process does not have write and search (execute) permission on the directory in which the socket is created.

On Linux, connecting to a stream socket object requires write permission on that socket; sending a datagram to a datagram socket likewise requires write permission on that socket. POSIX does not make any statement about the effect of the permissions on a socket file, and on some systems (e.g., older BSDs), the socket permissions are ignored. Portable programs should not rely on this feature for security.

So look at the permissions on the socket directory if getting a PermissionError: [Errno 13] Permission denied on bind() for unix sockets.

PermissionError: [Errno 13] Permission denied

I’m getting this error :

When running this :

Can someone tell me what I am doing wrong?

This happens if you are trying to open a file, but your path is a folder.

This can happen easily by mistake.

To defend against that, use:

The assertion will fail if the path is actually of a folder.

There are basically three main methods of achieving administrator execution privileges on Windows.

1. Running as admin from cmd.exe
2. Creating a shortcut to execute the file with elevated privileges
3. Changing the permissions on the python executable (Not recommended)

A) Running cmd.exe as and admin

Since in Windows there is no sudo command you have to run the terminal ( cmd.exe ) as an administrator to achieve to level of permissions equivalent to sudo . You can do this two ways:

• Find cmd.exe in C:\Windows\system32
• Right-click on it
• Select Run as Administrator
• It will then open the command prompt in the directory C:\Windows\system32
• Travel to your project directory
• Run your program

Via key shortcuts

• Press the windows key (between alt and ctrl usually) + X .
• A small pop-up list containing various administrator tasks will appear.
• Select Command Prompt (Admin)
• Travel to your project directory
• Run your program

By doing that you are running as Admin so this problem should not persist

B) Creating shortcut with elevated privileges

1. Create a shortcut for python.exe
2. Righ-click the shortcut and select Properties
3. Change the shortcut target into something like «C:\path_to\python.exe» C:\path_to\your_script.py»
4. Click «advanced» in the property panel of the shortcut, and click the option «run as administrator»

Answer contributed by delphifirst in this question

C) Changing the permissions on the python executable (Not recommended)

This is a possibility but I highly discourage you from doing so.

It just involves finding the python executable and setting it to run as administrator every time. Can and probably will cause problems with things like file creation (they will be admin only) or possibly modules that require NOT being an admin to run.
