简单的递归函数

# 指定数的阶乘
def sum(n):
    if n==1:
        return n
    else:
        return n*sum(n-1)
num=sum(5)
print(num)

# 阶乘递归求和
def total_sum(m):
    total=0
    for i in range(1,m+1):
        def sum(n):
            if n==1:
                return n
            else:
                return n*sum(n-1)
        total+=sum(i)
    return total
num=total_sum(5)
print(num)
