Question

Python

previous function:

wrtie a function that takes one argument. The function returns True if the number more than or equal to 0, otherwise it returns False.

write a function for main

create a variable and assign its value to true.

uses a while loop which runs as ling as the variable of the previous step is True, to get a number from the user

and if passing that nimber to the previous function, results in a True value returned, then add that number to a running sum. Otherwide make the loop stop without using break.

After the loops stop, print the running sum of all the balues the user entered

Answer 1

Program Screen Shot:

Sample Output:

Program Code to Copy:
# let the previous function be named "atleastZero"
def atleastZero(number):
return number >= 0 # True if number>=0, False otherwise

# function for main
def main():
more = True # to control the while loop
running_sum = 0

while more: # loop only when more == True
  
user_input = float(input('Enter a number: '))

# check if user_input >= 0 by using the previous function
if atleastZero(user_input):
running_sum = running_sum + user_input
  
else:
more = False
  
# after the loop stops
print('\nThe running sum is ',running_sum)

# call function main to run the program
main()
