4.  A User-Defined Function (UDF)
is a function created by the user to
perform specific tasks in a program
 A module can define functions,
classes, and variables
 A module can also include runnable
code
INTRODUCTION

5. # my_module.py
def greet(name):
return f"Hello, {name}!"
def add(a, b):
return a + b # Hello, World!
The sum of 5 and 3 is 8

6. Creating a User Defined Module
 A UDM can be created using a simple
function definition in the programming
language.
 It involves encapsulating code within a
recognizable name for easy access.
 Proper naming conventions are critical
for
 the clarity and usability of modules.

7.  Modules can be imported into other
programs using import statements.
 This allows the functions and
variables defined in the module to
be accessible.
 Different languages have varying
syntax and methods for importing
modules.
Importing User Defined Modules

8. Structure of a User Defined Module
 A UDM typically includes a header,
function definitions, and
documentation.
 It may also contain variables and
classes relevant to the functionality.
 Clear documentation within the module
is key for future reference and
usability.

9. Error Handling in User Defined Modules
Implementing error handling within
UDMs is crucial for robust
applications.
Use try-except blocks to manage
exceptions gracefully.
Proper error messages in UDMs can
significantly aid in debugging.

10. Example of User Defined Modules
# calculator.py
def add(x, y):
return x + y
def subtract(x, y):
return x – y
def multiply(x, y):
return x * y
def divide(x, y):
if y == 0:
return "Cannot divide by zero!"
return x / y

11. # main.py
import calculator
num1 = 10
num2 = 5
print("Addition:", calculator.add(num1,num2)) #15
print("Subtraction:", calculator.subtract(num1, num2)) #5
print("Multiplication:", calculator.multiply(num1, num2)) #50
print("Division:", calculator.divide(num1, num2)) # 2
