怎么解决Shadows name 'total' from outer scope 这问题？

Question

def sums(arg1, arg2):

total = arg1 + arg2
print("函数内 : ", total)
return total

total = sums(10, 20)
print("函数外 : ", total)

“total”那里显示：Shadows name 'total' from outer scope。

Answer 1

def sums(arg1, arg2):
    internal_total = arg1 + arg2
    print("函数内 : ", internal_total)
    return internal_total

total = sums(10, 20)
print("函数外 : ", total)
