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.

# 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()

assault rifle is a rapid-fire, magazine-fed rifle designed for military use. it is a shoulder-fired weapon that allows the shooter to select between semi-automatic (requiring you pull the trigger for each shot), fully automatic (hold the trigger and the gun continuously fires) or three-shot-burst modes.
