A) Create a variable name

Here is the Python program following the given steps:

# a) Create a variable name
my_matric_number = "12345678"  # b) Assign your matric number to it (replace with your actual number)

# c) Print 'My friend's matric number is different from mine.'
# d) Concatenate your matric number to this string while printing.
print("My friend's matric number is different from mine: " + my_matric_number)

Explanation:

• A variable named my_matric_number is created and assigned a placeholder matric number as a string.
• The print() function is used to display the required string.
• The + operator is used to concatenate (join) the literal string "My friend's matric number is different from mine: " with the value stored in the my_matric_number variable.
