Python – Check if file is readable
To check if a file is readable or not in Python, you can use the os library. Import os library, call the os.access() function and pass the file path and mode (os.R_OK, to check if file is readable) as arguments.
The syntax to call os.access() function to check if a file is readable is
os.access('path/to/file', os.R_OK) == 0
The function call returns a boolean value of True if the file is readable, or False if the file is not readable.
Note: The 'path/to/file' in the above expression should be replaced with the actual path of the file, including the file name, you want to check.
In the following program, we check programmatically if the file myfolder/sample.txt is readable or not.
import os path_to_file = "myfolder/sample.txt" if os.access(path_to_file, os.R_OK): print("File is readable.") else: print("File is not readable.")
File is readable.
In this tutorial of Python Examples, we learned how to check if a file is readable or not by using os.access() function.
