我是python的新手， 我有两个列表:

I am a newbie in python, I have two lists:

l1 = ['a','b','c','d']
l2 = ['new']

我想要这样的新列表

l3 = [('a','new'),('b','new'),('c','new'),('d','new')]

结合两个列表的最佳方法是什么?

What is the best way to combine the two lists?

推荐答案

>>> from itertools import product
>>> l1 = ['a','b','c','d']
>>> l2 = ['new']
>>> list(product(l1,l2))
[('a', 'new'), ('b', 'new'), ('c', 'new'), ('d', 'new')]
