我想知道程序哪里出错了？

Question

x=int(input("请输入x:"))
y=int(input("请输入y:"))
def mySum(x,y):
    s=0
    for i in range(x,y+1):
        s=s+i
    return s
print(s)

Answer 1

print(s)

改成

print(mySum(x,y))

 

x=int(input("请输入x:"))
y=int(input("请输入y:"))
def mySum(x,y):
    s=0
    for i in range(x,y+1):
        s=s+i
    return s
print(mySum(x,y))
