Ask For a Number Repeatedly and Print its Square with Python
Level: Beginner
Project Description
Your task for today is to write a Python program that repeatedly asks the user to enter a number and prints its square. The program should keep running until the user types "q" to quit.
This kind of loop is commonly used in real-world apps that continuously take user input, such as calculators or command-line tools.
Expected Output
The program should work like this:
As you can see, the program asks the user to enter a number. The user enters “4” and the program prints out the message “Square: 16”. The user can continue to enter numbers, but if they enter “q” the program should quit.
