Chapter #7 – Functions
Chapter #7 – Lab Exercises #2:
Write a program that uses a user defined function that accepts name and gender (as M for Male, F for Female) and prefixes Mr/Ms on the basis of the gender.
def prefix_name(name, gender):
"""
Prefix the name with Mr. or Ms. based on the gender.
Parameters:
name (str): The name to be prefixed.
gender (str): The gender ('M' for Male, 'F' for Female).
Returns:
str: The prefixed name.
"""
if gender.upper() == 'M':
return f"Mr. {name}"
elif gender.upper() == 'F':
return f"Ms. {name}"
else:
return "Invalid gender input. Please use 'M' for Male or 'F' for Female."
# User input
name_input = input("Enter your name: ")
gender_input = input("Enter your gender (M/F): ")
# Get the prefixed name
result = prefix_name(name_input, gender_input)
# Display the result
print(result)

How the Program Works :
1. Function Definition: The prefix_name function checks the gender parameter:
• If it is 'M' (or 'm'), it prefixes the name with "Mr."
• If it is 'F' (or 'f'), it prefixes the name with "Ms."
• If the input is neither, it returns an error message indicating invalid
input.
2. User Input: The program prompts the user to enter their name and gender.
3. Result Display: The program calls the prefix_name function with the user's
inputs and prints the prefixed name or an error message if the gender input
is invalid.
Example Output:
Enter your name: Alice
Enter your gender (M/F): F
Ms. Alice
Another Example:
Enter your name: Bob
Enter your gender (M/F): M
Mr. Bob
