Another way to check if a path exists (as long as you don't care if the path points to a file or directory) is to useos.path.exists. importos os.path.exists('./file.txt')# Trueos.path.exists('./link.txt')# Trueos.path.exists('./fake.txt')# Falseos.path.exists('./dir')#...

easy to use, it does have a potential pitfall. It does not distinguish between files and directories. So if there’s a directory with the same name as the file you’re checking, the function will still returnTrue. In the next section, we’ll explore how to specifically check for files....
