os.path.isfile

os.path — existence and type checks

Check whether a path exists and is a regular file.

Syntax

os.path.isfile(path)

"Regular file" is meant literally: sockets, named pipes and device files exist, yet isfile returns False for them. A link to a file counts as a file. not isfile(p) does not mean "directory" — the path may simply be missing. For reading it is safer to open the file and handle the exception than to check first.

Examples

import os
print(os.path.isfile(os.__file__))   # → True
print(os.path.isfile('/etc/hosts'))  # → True
print(os.path.isfile('/tmp'))  # → False (это каталог)
