Sum of all integers between two integers [closed]

Answer 1

You need this to get the sum:

ans = number1  + number2

Or is this not what you wanted to do? Since you commented: the numbers in between are 3,4,5, do you mean this?

>>> for i in range(number1+1,number2):
...     print i
... 
3
4
5

EDIT:
So, OP also needs sum of all numbers between two numbers:

>>> number1 = 2
>>> number2 = 6
>>> sum(range(number1 + 1, number2))
12

This second part given by OP.
