You can read the following articles to find out how to read files in Python and how to write files in Python. We can fix this error by ensuring by closing a file after performing an i/o operation on the file. 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.
While performing file operations in Python, we forget to close the file, and it remains in open mode. # Program to read the entire file (absolute path) using read() functionįile = open("C:\\Projects\\Python\\Docs\python.txt", "r")

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. PermissionError: Permission denied: 'C:\\Projects\\Python\\Docs' # Program to read the entire file (absolute path) using read() functionįile = open("C:\\Projects\\Python\\Docs", "r")įile "c:\Personal\IJS\Code\program.py", line 2, in 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. When we run our code back after setting the right permissions, you will get the following output. We can do this by running the following command. We can also give permission to specific users instead of making it readable to everyone. Let’s make the file readable and executable by everyone by executing the following command. We can fix the issue by changing the permission either to a particular user or everyone. 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.
rw-rw-rw- 1 root srinivas 46 Jan 29 03:42 python.txt In the case of Linux the issue we can use the sudocommand to run the script as a root user.Īlternatively, you can also check the file permission by running the following command. The same fix even applies if you are getting “ permissionerror winerror 5 access is denied” error In windows, we can fix this error by opening the command prompt in administrator mode and executing the Python script to fix the error. We are not executing the script in an elevated mode(admin/root). When we run the code, we have got PermissionError: Permission denied error because the root user creates the file. PermissionError: Permission denied: 'python.txt' Output Traceback (most recent call last):įile "C:/Projects/Tryouts/python.txt", line 2, in # Program to read the entire file (absolute path) using read() function Now let’s create a Python program to read the file and print its content. You can modify the file permission and ensure that it will be readable only by you. Let’s say you have a local CSV file, and it has sensitive information which needs to be protected. Case 1: Insufficient privileges on the file or for Python Let us try to reproduce the “ errno 13 permission denied” with the above scenarios and see how to fix them with examples.
There are three main reasons behind the permission denied error. We get this error mainly while performing file operations such as read, write, rename files etc. What is PermissionError: Permission denied error? In this article, we will look at what PermissionError: Permission denied error means and how to resolve this error with examples. 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: Permission denied error Case 1: Insufficient privileges on the file or for Python.How to Fix PermissionError: Permission denied error?.What is PermissionError: Permission denied error?.
