I don't understand the fourth exercise.

Question

Why 4 and not 3 for "eggs"?

Answer 1

you can change the variable value by readjusting it.

in the exercise:

eggs = 3 ----> 3 is the old value of the variable eggs.
eggs = 4 ----> now 4 is the new value of the variable eggs.

Python work with the new value of the variable not the old one.

Answer 2

Oh, thanks for the information! ;-)
