How to write a function in Phython that take two numbers x and y and returns the sum of numbers from x to y

Code that does not work:

def main():

first_number = int(input("Enter x: "))  # the input() function returns a string;

second_number = int(input("Enter y: "))

print(sum_between(x, y))

def sum_between(x, y):

    nums_between = range(x, y + 1)

    return sum(nums_between)

main()
