how to go about coding this in python?

Question

Write a function that asks for the user to enter a number of items they wish to purchase.

Answer 1

You can call this function and it will prompt the user to enter a number! If they give something that's not a positive integer, it will ask again.

def get_num_items():

while True:

num_items = input("Enter the number of items you want to purchase: ")

if num_items.isdigit() and int(num_items) > 0:

return int(num_items)

else:

print("Invalid input. The number of items must be a positive integer.")
