Function not defined error while using import

Question

I created two files in python First one is mym.py

def hello():
 print("Hello everyone")
 return
def summ(x,y):
 total=x+y
 return total

and next one is abc.py

import mym
hello()
x=summ(3,4)
print(x)

And the error msg which I am getting is...both the files are in same working directory and there is no error of module not found...its giving error of function not defined.

Traceback (most recent call last):
 File "C:/Users/Nisha/AppData/Local/Programs/Python/Python39/abc.py", line 3, in <module>
 hello()
NameError: name 'hello' is not defined

 x=summ(3,4)

What is the problem in function definition I am unable to trace...

• AlBlue: In this case, you need to prefix the name of the module on the function, so using mym.summ

Answer 1

The abc.py needs to be changed to:

from mym import *
hello()
x=summ(3,4)
print(x)

Otherwise you cannot access the functions.

Answer 2

You can try like this:

 import mym
 mym.hello()
 x = mym.summ(3,4)
 print(x)
