python - 如何从列表中创建单词对列表

Question

我在文件“temp”中有一个单词列表:

 1. the 
 2. of
 3. to
 4. and
 5. bank

等等

我如何提高它的可读性？

import itertools
f = open("temp.txt","r")
lines = f.readlines()
pairs = list(itertools.permutations(lines, 2))
print(pairs)

我迷路了，请帮忙

Answer 1

import itertools

with open("temp.txt", "r") as f:
    words = [item.split(' ')[-1].strip() for item in f]

pairs = list(itertools.permutations(words, 2))
print(pairs)

打印(使用 pprint 提高可读性):

[('the', 'of'),
 ('the', 'to'),
 ('the', 'and'),
 ('the', 'bank'),
 ('of', 'the'),
 ('of', 'to'),
 ('of', 'and'),
 ('of', 'bank'),
 ('to', 'the'),
 ('to', 'of'),
 ('to', 'and'),
 ('to', 'bank'),
 ('and', 'the'),
 ('and', 'of'),
 ('and', 'to'),
 ('and', 'bank'),
 ('bank', 'the'),
 ('bank', 'of'),
 ('bank', 'to'),
 ('bank', 'and')]
