python - 如何使用协程在两个列表之间交替打印？

Question

我有两个 python 简短列表，我是初学者。如果有人可以帮助我编写协程，通过一次打印一项来使我的列表交替出现，那将会有很大的帮助。

cars = ['BMW', 'Benz','Tesla']
veggies = ['Broccoli', 'Carrots', 'Spinach']
for item in cars:
    print(item)

for item in veggies:
    print(item)

Answer 1

IIUC:

cars = ['BMW', 'Benz','Tesla']
veggies = ['Broccoli', 'Carrots', 'Spinach']
for i in zip(cars,veggies):
    print('\n'.join(i))

或者:

cars = ['BMW', 'Benz','Tesla']
veggies = ['Broccoli', 'Carrots', 'Spinach']
for x,y in zip(cars,veggies):
    print(x)
    print(y)

两者都会交替使用两个列表

协程没有用，这里需要

如果列表有不同的长度:

import itertools
for x,y in itertools.zip_longest(cars,veggies):
    print(x)
    print(y)
