Unit3-04: If..Then..ElseIf..Else

Learning Outcome

At the end of this lesson, you will be able to:

• create if..then..elsif..else statements

Quiz Questions

With a pencil and paper, answer the following questions:

1. Write the line of code you need before you can use the random function in Python.

2. Write the line of code in Python to generate a random number between 10 and 20 and assign it to a variable called "random_num".

3. Create the pseudocode for a program that does the following:

   • Generate a random number between 1 and 100 that represents the number of smarties in the smartie jar.

   • Ask the user how many smarties are in the smartie jar.

   • If they guess correctly, tell them so.

   • Otherwise, tell them they guessed incorrectly.

4. Create 2 test cases for the above program: 1 for a user that guesses correctly and 1 for a user that guesses incorrectly.

Review

• how to generate random numbers

• if..then..else statements

  • Note: ELSE does not need a condition. See the pseudocode below:

IF (temperature is below 5 degrees Celsius) THEN

WEAR a jacket

ELSE

WEAR a hat

ENDIF
