CodeWars-Sum of Numbers

Given two integers a and b, which can be positive or negative, find the sum of all the numbers between including them too and return it. If the two numbers are equal return a or b.

Note: a and b are not ordered!

def get_sum(a,b):
    #good luck!
    if a == b:
        return a
    else:
        if a > b:
            a, b = b, a
        result = 0
        for num in range(a,b+1):
            result += num
        return result

First judge whether the two numbers are equal, the two numbers are equal, return a
is not equal, return the accumulation result
Because range() is closed before and open, the accumulation needs to include b, and the boundary is b+1
Note: a and b are not ordered!
a, b are unordered, if you do not judge the size and use it directly, it will lead to the possibility of result=0 to
judge the size

if a > b:
   a, b = b, a
