python homework print the sum of a range of numbers from x to y

[kirito85]

Hi, my for loop is not working, i can't figure out how to write the coding for this sum of range of x to y. Thanks.

 
import statistics 
print("This program prints the sum of a range of numbers from x to y")
print("For example, if x is 10 and y is 50, the program will print the sum of numbers from 10 to 50")
x = str(input('Please enter the value of x:' ))
y = str(input('Please enter the value of y:' ))


if x.isnumeric() and y.isnumeric():
    if (int(x) > 0) and (int(y) > 0):
        if int(y) > int(x): 
            sum_of_numbers = 0 
            counter = 0
            for counter in range(int(x), int(y)):
                sum_of_numbers += 1
                print("The sum of numbers between", x, "and", y, "is", sum_of_numbers)
            
        else:
            print("You did not enter a value of y that is greater than x!")
            print("Unable to continue. Program terminated.")        
    else:
        print("One or more of your inputs are not greater than zero")
        print("Unable to continue. Program terminated.")
else:
        print("One or more of your inputs are not numeric!")
        print("Unable to continue. Program terminated.")
