所以我正在编写一个带有2个列表并切换其值的函数.我将有2个清单

list_one = [1, 2, 3]
list_two = [4, 5, 6]

我想切换他们的价值观.输出应该看起来像

#Before swap
list_one: [1, 2, 3]
list_two: [4, 5, 6]



#After swap
list_one: [4, 5, 6]
list_two: [1, 2, 3]

这是一个小小的学校作业,所以我想使用一个for循环,它就是我所说的.

到目前为止,这是我的代码:

def swap_lists(first, second):
    if len(first) != len(second):
        print "Lengths must be equal!"
        return
    first == second
    print second

list_one = [1, 2, 3]
list_two = [4, 5, 6]
print "Before swap"
print "list_one: " + str(list_one)
print "list_two: " + str(list_two)
swap_lists(list_one, list_two)
print "After swap" …
