What does def do again?

Answer 1

def "def"ines the name of a new function.

def add(x, y): <--- We're defining a function that adds two numbers together and naming it "add"
return x+y <--- returns the value of our two numbers added together

print(add(4, 7)) <--- asks our program to print the value returned by our function named "add"

Answer 2

I had a hunch that was the case. Thanks very much. I appreciate it.
