Python simple for and while loops exercise.

Would like to compare my solution for this to see where I'm going wrong.

Professor's exercise:

_________________________________________________________________________________________-

def sum_up_to1(n): """  04: Calculate the sum up to n (including n)  Input n is a positive integer.  The return value should be the sum of 1+2+3+.....+n  You should do this with a for loop """  

# test for Q4 print(sum_up_to1(100)) print("--"*10)  def sum_up_to2(n): """  05: Calculate the sum up to n (including n)  Input n is a positive integer.  The return value should be the sum of 1+2+3+.....+n  You should do this with a while loop  """ 

# test for Q5 print(sum_up_to2(100))

Thank you in advance for your help! :)
