Chapter 5: Problem 33

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

Question: Write a Python program that prompts the user to enter 10 numbers and calculates the sum of those 10 numbers. Answer: ```python total = 0 for i in range(10): user_input = int(input("Enter a number: ")) total += user_input print("The total of the numbers you entered is:", total) ```

Step by step solution

Initialize running total variable

First, we need to create a variable to hold the sum of the numbers the user inputs. We will initialize this variable with a value of 0. The code for this step is: ```python total = 0 ```

Create a loop that iterates 10 times

Using a 'for' loop, we will iterate 10 times with the help of the range function, which will ensure the loop iterates exactly 10 times. The code for this step is: ```python for i in range(10): ```

Ask the user for a number

Inside the loop, we will use the input() function to get the user's input and store it in a variable. We will also use the int() function to convert the user input, which is a string by default, to an integer. This will allow us to perform arithmetic operations with the user's input. The code for this step is: ```python user_input = int(input("Enter a number: ")) ```

Update the running total

After receiving the user's input, we will update the running total by adding the value of user_input to the total variable. The code for this step is: ```python total += user_input ```

Display the running total

Once the loop has finished running, we will display the value of the running total to the user. The code for this step is: ```python print("The total of the numbers you entered is:", total) ``` Here is the complete code: ```python total = 0 for i in range(10): user_input = int(input("Enter a number: ")) total += user_input print("The total of the numbers you entered is:", total) ```
