Great job! We covered a ton of material in this lesson and we’ve increased the number of tools in our Python toolkit by several-fold. Let’s review what we’ve learned this lesson:

• Boolean expressions are statements that can be either True or False
• A boolean variable is a variable that is set to either True or False.
• We can create boolean expressions using relational operators:
  • ==: Equals
  • !=: Not equals
  • >: Greater than
  • >=: Greater than or equal to
  • <: Less than
  • <=: Less than or equal to
• if statements can be used to create control flow in your code.
• else statements can be used to execute code when the conditions of an if statement are not met.
• elif statements can be used to build additional checks into your if statements

Let’s put these skills to the test!
