你这已经不是简化的问题了,看了一半,提出两点提醒:
1. 让变量名具有一定含义
2. letters 这个变量可以通过标准库 import string; string.ascii_lowercase 进行调用

你可以试试 itertools.product
ttwo = [''.join(chars) for chars in product(letters, repeat=2)]
或者用 ttwo * letters 去生成 tthree
tthree = [char + word for char in letters for word in ttwo]
或者用 letters * two 去生成 three
three = [[char + url[0]] for char in letters for url in two],这里顺序会不一致,如果要顺序一致,可以用 letters * two[0:len//2] + letters * two[len//2:]

应该是用排列吧,from itertools import permutations

字符串相加可以放到 dataframe 里批量去加,这样比在循环里加然后 append 快很多

这个命名看得我脑阔疼

楼主你先了解一下 markdown code block 再说。

@xingheng 我去学了下 markdown,感觉发现新大陆了,但是帖子删不了只能保持现状了。。。
