一个python的问题

def fun(m,n):
sum = 0
for i in range(pow(1,101)):
for i in range (pow(2,51)):
for i in range(pow(-1,11)):
学艺不精，搜肠刮肚用for循环写了个代码，果然报错了
能不能救一下

def fun(m, n):
    return sum(i**m for i in range(1,n+1))

print(fun(1,100)+fun(2,50)+fun(-1,10))

def fun(m,n):
    lst = []
    for i in range(1,n+1):
        lst.append(i**m)
    return sum(lst)

print(fun(1,100)+fun(2,50)+fun(-1,10))
