How can I run a script after importing it?

Problem

I would like to import a script containing many functions and then run them, so that I can use the function. I may have misunderstood the purpose of import. I am working in Jupyter.

Reprex

#Create the script in a local folder

%%writefile test.py
c = 500

def addup(a,b,c):
    return a*b + (c)

#import the file and use it

import test
addup(1,5,c)


#Error message

---------------------------------------------------------------------------
# NameError                                 Traceback (most recent call last)
# <ipython-input-1-71cb0c70c39d> in <module>
#       1 import test
# ----> 2 addup(1,5,c)

# NameError: name 'addup' is not defined

Any help appreciated.

>Solution :

You have not called the function! You need a dot . to call a function from a module.

This is the correct syntax:

import test
result = test.addup(1,5,c)

Import a specific function:

from test import addup
addup(1,5,c)

Importing all of the module’s functions:

from test import *
addup(1,5,c) # this way you can use any function from test.py without the need to put a dot
