How to judge the existence of a file in python? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

Method 1, os.path.existsimport os

Print (os.path.exists ('log.txt'))

This is my favorite method. It can judge not only whether a file exists, but also whether a folder exists. Method 2, os.path.isfileimport os

Print (os.path.isfile ('log.txt'))

The isfile method can determine whether the given path is a file, and if so, it proves that the file exists, otherwise, the file does not exist. Method 3, try to open the file try in read mode:

With open ('log.txt', 'r') as fh:

Pass

Except FileNotFoundError:

Print ('does not exist')

If the file does not exist, a FileNotFoundError exception will be thrown, and the existence of the file can be judged by catching the exception by except. The with keyword is used to open the file, so there is no need to actively close the file method 4, use pathlibfrom pathlib import Path

Config = Path ('log.txt')

Print (config.is_file ())
