Exercise 4.7

Try to complete this exercise using only the material that was presented before it.

Question 1

Take a user input number (by using the input() function) and print out the value squared. Make sure to use appropriate messages for the input and the print out.

Question 2

Use a string slice to print out a user input backwards. Use an appropriate message for the input.

Question 3

A spoonerism is a play on words where you take a phrase (normally one consisting of two words) and you swap the first letters of two of the words. For example “marco polo” becomes “parco molo”. Write a program which takes the two words as separate inputs (use appropriate messages for each, such as “Word 1: “ and “Word 2: “) and spoonerises them by printing them in one line with the first letters swapped. Use lower case for simplicity.

Test your code with the following examples:

• “lighting a”, “fire”

• “bad”, “money”

• “jelly”, “beans”

• “pack of”, “lies”

Question 4

Create a script similar to Question 3, except swapping the first 2 letters of each word. Now “marco polo” becomes “porco malo”.

Test your code with the following example:

• “crushing”, “blow”
