使用Python消除数据文件中的特定数字

我有一个大文件，我想删除数据文件中的所有值“24”。我已经使用了这个代码，但它没有做我想要的。请给我一些建议。谢谢

这是数据文件

24,24,24,24,24,24,1000,1000,24,24,24,1000,1000,1000,1000,24,24,24,24,24,24,24,24,24,24,1000,1000,1000,1000,1000,1000,1000,1000,24,24,24,24,1000,1000,1000,1000,24,1000,24,24,24,24,1000,1000,1000,1000,1000,24,24,24,24,24,24,1000,24,24,24,24,1000,1000,1000,1000,1000,1000,1000,1000,1000,24,24,24,24,1000,1000,1000,1000,24,1000,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,1000,1000,24,24,24,24,24,24,1000,1000,1000,24,24,24,24,1000,1000,1000,1000,1000,1000,1000,1000,1000,24,24,24,24,24,24,24,24,24,24,24,24,24,1000,1000,24,24,24,24,24,24,24,24,24,1000,1000,1000,24,24,24,1000,24,24,1000,1000,24,24,24,24,1000,1000,1000,1000,1000,1000,1000,24,24,24,1000,1000,1000,1000,1000,1000,24,24,24,1000,1000,1000,1000,1000,1000,1000,24,24,24,24,1000,1000,24,1000,1000,24,24,1000,1000,1000,1000,1000,1000,1000,24,24,24,1000,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,1000,1000,24,24,24,1000,1000,1000,1000,1000,24,24,24,24,24,24,24,24,1000,1000,1000,1000,1000,24,24,24,24,24,24,1000,24,24,24,24,24,24,24,24,24,1000,1000,1000,1000,1000,1000,24,24,24,24,24,24,24,24,24,24,1000,1000,1000,24,1000,1000,1000,1000,24,24,1000,1000,24,24,24,24,24,24,24,1000,24,24,24,24,24,24,1000,1000,1000,1000,1000,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,24,1000,1000,1000,1000,1000

content = open('txt1.txt', 'r').readlines()
cleandata = []
for line in content:
    line = {i:None for i in line.replace("\n", "").split()}
    for value in line.copy():
         if value == "24":
            line.pop(value)
    cleandata.append(" ".join(line) + "\n")

open('txt2.txt', 'w').writelines(cleandata)

这应该做到：

content=open（'txt1.txt'，'r'）。readlines（）
cleandata=[]
对于内容中的行：
行=行。替换（'24'，''）
cleandata.append（第行）
打开（'txt2.txt'，'w'）。写入线（cleandata）

您可以使用正则表达式来匹配24并删除它

import re

regex24 = re.compile(r"\b24,?\b")

f = open('txt1.txt', 'r')
cleans = [regex24.sub("", line) for line in f.readlines()]

open('txt2.txt', 'w').writelines(cleans)

此代码有任何特定错误吗？或者根本没有给出正确的结果？它根本不做任何更改@Lorenzo Zane

line={…}

您创建了dict，它只包含一个唯一的键（i）。您可能需要列表或生成器，您可以在创建时使用

（i代表行中的i。如果i！=“24”），则拆分（“，”）

。这也会删除一些可能不应删除的内容，例如：

Hello 124

->

Hello 1

@thatguyfig我尝试了此操作，它确实删除了24个值，但用逗号“，”替换它们。如何删除它？扫描字符串时出现错误f=open（'BVE300_6.txt，'r'）^SyntaxError:EOLliteral@Alex8798注释中的代码在BVE300_6.txt之后缺少一个引号，可能这就是为什么您会遇到语法错误，我还更改了正则表达式以删除逗号，因为你同时更新了这个问题。谢谢，我现在尝试了你的代码，没有错误，但是我打开了文件，它实际上是空的@Alex8798您很可能提供了与读取相同的文件来写入。如果您想在相同的文件名和路径上使用我的答案，我已将其更新为有效。
