Importing all modules and using it

[rohitnirantar]

from os import path

path.exists("foo.txt")

Above code works fine. But lets say I want to import all modules in OS by
from os import *

how can i use path.exists here to verify file exists?

[gontajones]

import os
os.path.exists("foo.txt")

Importing star (asterisk, everything) is a Python Worst Practice.
So don't do that.
