从文件中删除单词并将其余部分保存到同一文件

Question

我有一个小问题

我希望将所有删除的单词上传到我犯错的同一个文件中：D

infile = "tada.txt"
outfile = "tada.txt"

word = "vul"
tada=(''.join(word))

delete_list = tada
with open(infile) as fin, open(outfile, "w+") as fout:
    for line in fin:
        for word in delete_list:
            line = line.replace(word, "")
        fout.write(line)

来自文本

this is vul great

如果文件中有单词vul

输出是

this is great

所以我希望相同的输出在同一个文件中

但问题是脚本删除了所有内容，文件仍然是空的

您可以使用 Python 的 fileinput 模块有效地“就地”更改文件。这是它如何用于您想要的（即从每一行中删除单词）。

注意，与您的代码不同，以下内容将删除整个 个单词，而不是每行中的一个字母。

import fileinput

filepath = "tada.txt"
banned = {"bfd", "vul", "wtf"}  # Disallowed words.

with fileinput.input(files=filepath, inplace=True) as file:
    for line in file:
        words = [word for word in line.split() if word.lower() not in banned]
        print(' '.join(words))
