How do I check whether a file exists without exceptions?

Question

How do I check if a file exists or not, without using the try statement?

Answer 1

Use os.path.isfile() with os.access():

import os

PATH = './file.txt'
if os.path.isfile(PATH) and os.access(PATH, os.R_OK):
    print("File exists and is readable")
else:
    print("Either the file is missing or not readable")
