Question

PLS JUST EXPLAIN IT TO ME IN A SIMPLIFIED MANNER.

thanks!!!

Answer 1

You take something specific:
I want to add 2+2
You write the code:

print(2 + 2)
4

Cool, what if i want to add any two numbers though...?

Okay, so obviously I will need two numbers as parameters. This is where the function comes in. Its just taking a problem and generalizing it.

def add2nums(x,y): #call it whatever
print(x + y) #using our parameters

So now weve defined our function. But nothings happening...

Call that function out!

add2nums(4,5)# <-- x and y == 4 and 5
9

Now instead of only being able to add 2 and 2, you can throw any two numbers in there and it will add them up. This is overly simple but shows a function in action
