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!

### Instructions

Optional: Little Codey is an interplanetary space boxer, who is trying to win championship belts for various weight categories on other planets within the solar system.

Write a space.py program that helps Codey keep track of their target weight by:

1. Checks which number `planet` is equal to.
2. It should then compute their weight on the destination planet.

Here is the table of conversions:

# Planet Relative Gravity
1 Venus 0.91
2 Mars 0.38
3 Jupiter 2.34
4 Saturn 1.06
5 Uranus 0.92
6 Neptune 1.19
Click to see a hint! To compute their weight on the planet they are fighting on, multiply their earth weight and the relative gravity of that planet:
``````if planet == 1:
weight = weight * 0.91
elif planet == 2:
weight = weight * 0.38
elif planet == 3:
weight = weight * 2.34
elif planet == 4:
weight = weight * 1.06
elif planet == 5:
weight = weight * 0.92
elif planet == 6:
weight = weight * 1.19
