Debugging

When you're working as a professional developer, you'll typically write code on your computer and test it by yourself before it's deployed to users.

That first part of the process is called debugging. You write some code, run it, and if it doesn't work, you fix the bugs. You repeat this process until you're confident that your code works as expected.

Run vs. Submit

At Boot.dev, the Run button is for debugging. The Submit button mimics the idea of publishing your code for production use.

You should be debugging your code using the Run button. You should be adding print() statements to your code to make sure it's doing what you think it's doing at different points in the code.

Write a line to calculate a value
print() the value you calculated
Run the code
Did it print what you expected? If not, fix it
Repeat

You will never lose XP or be penalized on Boot.dev for using the run button. However, there are consequences for submitting broken code, just like there are career consequences for pushing broken code to your users!

The Submit Button Will Run Additional Tests

When you use the Run button, a few tests will run against your code. However, the Submit button will run additional tests that you're not able to debug against. That's what keeps it fun and realistic (it's so hard to know what your users will do with your code!).

Assignment

Complete the take_magic_damage function. It should return the new health after calculating how much magic-type damage the player takes. Here is a description of the parameters:

health: The player's starting health
resist: The player's magic resistance. This reduces the damage they take by a static amount
amp: The attacker's magic amplification. This increases the damage they deal by a multiplier
spell_power: The base damage of the spell

First, calculate the total maximum damage to be inflicted by multiplying the spell_power by the amp. Then, subtract the resist from the total damage to get the actual damage dealt. Apply that damage to the player's health and return the new health.
