Stuck? The idea behind input and output
input() waits for one line typed by the user and gives it back as text. Keep it in a variable to use it later.
Each call reads one line, so a program that needs two answers calls input() twice.
name = input()
town = input()
print(f"{name} lives in {town}.")Watch for: Don't put a question inside input("...") here: the prompt is printed too, and the tests compare everything printed.
