Computer Science Aim: (b) Write the code in main.py:
Activity 6.5:
Creating and using a Python module
FOR ONLINE READING ONLY
Students will learn how to create a
Python module and use it in a separate
script. This activity will help students
understand the concepts of modularity
and code reuse in Python.
Materials Required:
(a) Computer with Python installed
(b) Text editor or Integrated
Development Environment (IDE)
such as PyCharm, Visual Studio
Code, IDLE or Thonny.
(c) Sample Python codes.
Instructions:
Step 1: Create the module
(a) Open your text editor or IDE.
(b) Create a new file and name it
mymodule.py.
(c) Write the following code in
mymodule.py:
# Example code for mymodule.py
CONSTANT_PI = 3.14159
def add(a, b):
return a + b
def subtract(a, b):
return a - b
# More functions can be added as needed
(d) Save the file.
Step 2: Use the Module
(a) Create another new file in your text
editor or IDE and name it main.py.

# Example code for main.py
import mymodule
result_add = mymodule.add(500, 1300)
result_subtract = mymodule.subtract(101, 17)
print(“Addition result:”, result_add)
print(“Subtraction result:”, result_subtract)
(c) Save the file.
Step 3: Run the Script
(a) Open a terminal or command
prompt.
(b) Navigate to the directory where you
saved mymodule.py and main.py.
(c) Run the main.py script by typing
python main.py command and
pressing Enter:
(d) Observe the output in the terminal.
It should display the results of the
mathematical operations and the
values of the constants.
Extension Activity:
(a) Add more functions to
mymodule.py, such as
modulus(a, b) and power(a, b),
and use them in main.py.
(b) Create another module named
geometry.py with functions
like area_of_circle(radius)
and circumference_of_
circle(radius). Use these
functions in a new script named
geometry_test.py.
Deliverable:
Python module file, mainscript and
screenshots of your python code.
