We are trying to open the file filename.txt, and if the file doesn’t exist, an IOError exception is raised and “File not accessible” message is printed:eval(ez_write_tag([[728,90],'linuxize_com-box-3','ezslot_7',139,'0','0'])); If you are using Python 3, you can also use FileNotFoundError instead of IOError exception.eval(ez_write_tag([[728,90],'linuxize_com-medrectangle-3','ezslot_0',156,'0','0'])); When opening files, it is recommended to use the with keyword, which makes sure the file is properly closed after the file operations are completed, even if an exception is raised during the operation. Checking if a file exists and opening that file are two different operations in this example. Change File Permission. Working with files and interacting with the file system are important for many different reasons. Path.is_file()¶ Return True if the path points to a regular file (or a symbolic link pointing to a regular file), False if it points to another kind of file.

It includes so called “pure” classes, which operate on strings but do not interact with an actual filesystem, and “concrete” classes, which extend the API to include operations that reflect or modify data on the local filesystem. Both functions support on Python2 and Python3 versions. rename ("src/.config", "src/.stuffconfig") Here is the same thing done using the pathlib module: from pathlib import Path Path ("src/stuff").
