Employ the EAFP coding style and
try to open it.
import errno try: with open(path) as f: # File exists except IOError as e: # Raise the exception if it is not ENOENT (No such file or directory) if e.errno != errno.ENOENT: raise # No such file or directory
This will also avoid race-conditions if another process deleted the file between the check and when it is used. This race condition could happen in the following cases:
import os os.path.isfile('/path/to/some/file.txt')
import pathlib path = pathlib.Path('/path/to/some/file.txt') if path.is_file(): ...
To check whether a given path exists or not, you can follow the above EAFP procedure, or explicitly check the path:
import os path = "/home/myFiles/directory1" if os.path.exists(path): ## Do stuff
