Answer by Milad Koohi for How do I check whether a file exists without exceptions?

All the answers were related to different versions of PythonBut I generally write the code on the version that is minimal.

from os.path import existsfrom sys import argvscript,form_file = argvfile = open(from_file) if exists(from_file):    print "File path is invalid."  else:       print "File does not exist."
