How to use Python to check if a file exists?

[Erza Zoya]

I forgot the code to check a file's availability on the system. Can you remind me guys? I am using Python.

Use os.path.exists() to check if a file exists in Python. Import the os module, then call os.path.exists('filename.txt') which returns True if the file exists, False otherwise. Alternatively, use pathlib.Path('filename.txt').exists() for a modern approach. Both methods are simple and reliable for file existence checking.

To check if a file exists in Python, you can use either the os.path module or the pathlib module. With os.path, you call a function to check the file’s path. With pathlib, you use an object-oriented approach. Both methods return true if the file exists, and false if it does not.
