Python - 从两个列表中分配值来回答

Question

我是python的新手！

players = ["Matt","Joe", "Barry","Billy"]
numbers = [1,2,3,4]

def assignment(players, numbers):
    for i in players:
        for j in numbers:
            print i,j
assignment(players,numbers)

我的尝试就在上面。

我想尝试回答=

Matt 1
Joe 2
Barry 3
Billy 4 

但是每分钟给每个号码分配一个号码！关于如何解决这个问题的任何建议？

Answer 1

使用zip

players = ["Matt","Joe", "Barry","Billy"]
numbers = [1,2,3,4]

for a in zip(players, numbers):
    print(*a)

如果您的列表长度不同，zip只会将另一个列表中具有相应索引的项目配对，如果您希望其他项目可以在python3中使用itertools.zip_longest，指定python的fillvalue以填充空的项，例如：

from itertools import zip_longest

players = ["Matt","Joe", "Barry","Billy", "Johnson", "Riyad"]
numbers = [1,2,3,4]

for a in zip_longest(players, numbers, fillvalue=0):
    print(*a)

输出

Matt 1
Joe 2
Barry 3
Billy 4
Johnson 0
Riyad 0

Answer 2

def assignment(players, numbers):
    for i, j in zip(players, numbers):
        print i,j
