Hello Guys, I have written an application using Python to help read log files (txt files). Sometimes run code I got an exception file not found. My code is like this:
datas = []
with open('iis-apache-logs.txt') as f:
datas = f.readlines()
i = 0
for row in datas:
i += 1
print(f'{i}: {row}') My question is how to check If a file exists or not in Python?
Thanks in advance.

To check whether a file has existed or not. I usually use
os.path.exists()function to check. Like this:import os.path file_exists = os.path.exists('log-20220501.txt') if file_exists: print("Existed") else: print("Not Existed")I hope this answer is useful for you.

Easy way to use
pathlib.Path.exists(path)function. This function will return a true/false value. Like this:from pathlib import Path file_exists = Path('test-log.txt') if file_exists.exists (): print("Existed") else: print("Not Existed")
