我想用列表中的双引号替换单引号 [英] I want to replace single quotes with double quotes in a list

问题描述

因此，我正在编写一个程序，该程序需要一个文本文件，将其分解为单词，然后将列表写入新的文本文件.

So I am making a program that takes a text file, breaks it into words, then writes the list to a new text file.

我遇到的问题是我需要列表中的字符串使用双引号而不是单引号.

The issue I am having is I need the strings in the list to be with double quotes not single quotes.

例如

当我想要这个["dog","cat","fish"]

这是我的代码

with open('input.txt') as f:
    file = f.readlines()
nonewline = []
for x in file:
    nonewline.append(x[:-1])
words = []
for x in nonewline:
    words = words + x.split()
textfile = open('output.txt','w')
textfile.write(str(words))

我是python新手，对此一无所获. 有人知道如何解决这个问题吗?

I am new to python and haven't found anything about this. Anyone know how to solve this?

推荐答案

您不能更改str对list的工作方式.

You cannot change how str works for list.

关于使用 JSON格式(对于字符串使用")的情况.

How about using JSON format which use " for strings.

>>> animals = ['dog','cat','fish']
>>> print(str(animals))
['dog', 'cat', 'fish']

>>> import json
>>> print(json.dumps(animals))
["dog", "cat", "fish"]

---

import json

...

textfile.write(json.dumps(words))
