Question

I have just started learning python version 3 and trying to create a file in python.
I placed the file in all the places which is shown by this set of command.

import sys
sys.path

The file has a simple function something like this

 def hello(var):
     print("Hello "+var)

But when I run it

hello("Google")

I am getting NameError.

Please can anybody help me? I am using Windows. Or is it that I have to call by file name and not by function name? If so, how should I call it?
Thanks in advance to whoever helps me.

Answer 1

You need to import your file first:

import myModule

(assuming your file is called myModule.py)

Then you can call the function like this:

myModule.hello('world')

Alternative syntax:

from myModule import hello
hello('world')
