Question

Sum of Numbers Design a function that accepts an integer argument and returns the sum of all the integers from 1 up to the number passed as an argument. For example, if 50 is passed as an argument, the function will return the sum of 1, 2, 3, 4, . . . 50. Use recursion to calculate the sum. Demonstrate the function in a program.

Answer 1

Answer:

# define main to get an argument from the user, call the function, and display the final values

def main():

 # ask an argument from the user.

 number = int(input('Enter a positive integer: '))

 # solve the integral thing of the number by putting the user's argument in the addition() function

 finalSum = addition(number)

 # display the final value integral thing

 print("The integral of this number is ", finalSum, ".")

# define an addition function to find the integral

def addition(num):

 # make an if-statement to test filter things out of your calculations. In this case, 1.

 if num == 1:

   #if 1, return 1. because 1 + (1 - 1) = 1

   return 1

 # this is where the recursion actually is. This is the part that calculates

 else:

   return num + addition(num-1)

# call your main function

main()

Answer 2

In this exercise we have to use the computer language knowledge in python to write the code.

This code can be found in the attachment.

So we have what the code in python is:

def main():

number = int(input('Enter a positive integer: '))

finalSum = addition(number)

print("The integral of this number is ", finalSum, ".")

def addition(num):

if num == 1:

 return 1

else:

  return num + addition(num-1)

main()
