Question

Write an interactive program that repeatedly asks the user to input a number until "Enter" is hit. Your program should create a file named "numbers.txt" where all the numbers are written one below the other, and the last line should display the sum of all the input, after the string "The sum of your numbers is".

For example, if the user inputs 3, 5, 7, 10, -3, 5.2, then the file "numbers.txt" should contain:

3

5

7

10

-3

5.2

The sum of your numbers is 27.2

Answer 1

# Open a file for writing

f = open("numbers.txt", "w")

# Initialize a variable to store the sum

sum = 0

# Continuously prompt the user for input

while True:

# Get the user's input

num = input("Enter a number: ")

# If the user just hits Enter, break out of the loop

if num == "":

break

# Convert the input to a float and add it to the sum

sum += float(num)

# Write the number to the file

f.write(num + "\n")

# Close the file

f.close()

# Print the sum

print("The sum of your numbers is", sum)
