check file Existing with Python Script

Are there any way to check the file existence in Python script.

 

Yes there is, you just need the pathlib library

if you want to search inside all the sub directories of a directory for your file, you can use this recursive function (DFS)

Code:

from pathlib import Path

def file_exists(origin,filename):
 
    for i in [x for x in Path(origin).iterdir()]:
     
        if i.name == filename:
            return True
        elif i.is_dir():
            t = file_exists(i,filename)
            return t
    return False

Usage:

Code:

print(file_exists(/home/user/Documents/,'myhomework.pdf')

But if you want to check the existance of a file in the running directory you can use this:

Code:

from pathlib import Path
myfile = 'main.py'
print(Path(myfile).exists())

Hope it helps
