* The code:
age = input("How old are you? ")
height = input("How tall are you? ")
weight = input("How much do you weigh? ")


print(f"So, you're {age} old, {height} tall and {weight} heavy.")

* When will input run? At the variable initalization or when calling the function?

* How do I debug, and step through the code to see what's happening in the background (and possibly see the anwser for the prev question)?
