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:

• 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:

By completing this challenge we are going to learn how to define our own functions in Python.
We will also assign parameters to our functions.

Look at the code below used to calculate the volume of a cube. This code is based on the use of a function called getVolumeOfCube(). This function takes one parameter (width) and return the volume of the cube (in mL).

def getVolumeOfCube(width):
    volume = width * width * width
    #This calculates the volume in cubic millimeters. Divide it by 1000 to get this volume in mL
    volume=volume/1000
    return volume

#Main Program Starts Here
cubeVolume=getVolumeOfCube(50)
print("The volume of a cube with a side of 50mm is: " + str(cubeVolume) + " mL.")

Challenge #1:

• getVolumeOfCylinder(radius, height)
• getVolumeOfCuboid(width, length, height)
• getVolumeOfCone(radius, height)
