Chapter 5: Problem 24

Write a loop that asks the user to enter a number. The loop should iterate 10 times and keep a running total of the numbers entered.

Short Answer

Expert verified

Answer: The code provided in the solution creates a loop that executes 10 times, asking the user to enter a number during each iteration. It calculates the running total of the numbers entered by the user and displays the final result. The code uses a for loop with the range function.

Step by step solution

Set up the loop

First, set up a for loop that will execute 10 times. We can use the range function to create a loop with a defined number of iterations. Here's how you can set up the loop: ```python for i in range(10): # code to ask user input and update the running total will go here ```

Ask the user to enter a number

Inside the loop, use the input() function to ask the user to enter a number. Make sure to convert the user's input to an integer, as the input() function returns a string by default. Here's how to get user input and convert it to an integer: ```python number = int(input("Please enter a number: ")) ```

Initialize a variable for the running total

Before the loop, initialize a variable called 'running_total' to store the sum of the numbers entered by the user. Initially, set its value to 0. ```python running_total = 0 ```

Update the running total

Inside the loop, after getting the user's input, add the number to the running total. Here's how to do it: ```python running_total += number ```

Display the running total

Once the loop finishes executing, print the final value of the running total. Here's how to do it: ```python print("The running total of numbers entered is:", running_total) ```

Completed Code

Combining all the steps, here is the complete code: ```python running_total = 0 for i in range(10): number = int(input("Please enter a number: ")) running_total += number print("The running total of numbers entered is:", running_total) ``` With this code, the loop will execute 10 times, asking the user for a number and updating the running total each time. The final running total will be displayed once the loop finishes.
