What’s My Username?

Learning objectives

In this challenge we will use string manipulation techniques to manipulate text data.
In Python a String is a piece of text. It can contain letters, numbers and punctuation signs.

Hello my name is Bond, James Bond

Look at the following code which highlights some key string manipulation techniques:

Using the code above can you tell how to use Python to:

• Prompt the user to enter their firstname?
• Concatenate two strings together to create a longer string?
• Retrieve the first character of a string?
• Convert a string to uppercase?
• Calculate the length (number of characters) of a string?
• Convert a number into a string?

Challenge:

Write a program that asks the end-user to enter the following information:

• Firstname
• Lastname
• Year Group

The program should then generate the end-user’s username using the following rules:

• 2-digit year group + first letter of firstname + lastname
• The username should be all lowercase
• If the year group is in 1 digit only (e.g.: 7) then add a “0” in front to make it two digits e.g. “07”

Test your program with the following data:

Firstname	Lastname	Year Group	Expected Output	Actual Output
John	Lennon	7	07jlennon
Paul	McCartney	11	11pmccartney
George	Harrison	8	08gharrison
Ringo	Starr	9	09rstarr
