我正在阅读上述特定路径中的#!/usr/bin/env python import os import sys import time import webbrowser from io import BytesIO import uuid import httplib import StringIO import re import difflib import mmap import json directory =os.path.join("C:\Users\Desktop\Working\pcm-audio\English") for subdir, dirs, files in os.walk(directory): for file in files: if file.endswith(".txt"): content=json.load(file) if "status_code" in content: if content["status_code"]==0: print("valid")文件。稍后我只检查.txt文件中的status_code。

如果是0，那么我打印为有效，否则无效。后来我在.txt文件中找到转录和解释变量（我在开头展示了它包含的内容），它有一个值列表。

比较这些值，我比较了它，但我没有得到输出。我在这里使用RegEx犯了一个错误：.txt

if line.find("transcriptions") == ("Interpretations"):工作正常。但不是status_code和transcriptions。

有人可以告诉我这里的错误是什么吗？

Answer 1

如果没有关于find实现的详细信息，那么难以回答。

我会提出一种完全不同的方法。您正在阅读的输入看起来像有效的JSON。为什么不用pythons json模块加载它。这将为您提供一个非常好的界面的python dict。

import json
info=json.load("filename.txt")
if "status" in info:
  print(info["status"])

JSON完全支持数组。您可以非常轻松地添加验证

if "actions" in info:
  value=info["actions"]
  if not isinstance(value, list):
    raise TypeException("expecting a list of actions")

我会避免使用正则表达式。现在你正在使用的正则表达式很容易阅读，但如果你的输入解析变得更复杂，这肯定会改变。正则表达式适用于验证，但我不会尝试用它们解析JSON。

注意json.loads和json.load之间的区别。 Loads将尝试解析一个字符串，load将读取一个文件。

修改我已经阅读了find。它似乎返回一个布尔值。你不应该将它与字符串进行比较。在python 3中，这总是错误的。这可能是您代码中的问题。

<强> EDIT2：阅读文件列表：

filenames=["a.txt","b.txt","c.json","d.asdadf"] for filename in filenames: content = json.load(filename) if "status" in content: print(filename+" contains a status entry") status_entry=content["status"] print("it is: "+str(status_entry)) else: print(filename+" does not contain a status entry")

根据您的设置，这可能看起来像这样，但我还没有测试过：

directory =os.path.join("C:\Users\hemanth_venkatappa\Desktop\Working\pcm-audio\English") for subdir, dirs, files in os.walk(directory): for file in files: if file.endswith(".txt"): content=json.load(file) if "status_code" in content: if content["status_code"]==0: print("valid")

您可以使用glob来获取文件名： https://docs.python.org/2/library/glob.html

import glob glob.glob("path_to_folder/*.txt")

将返回文件名列表，例如

["path_to_folder/a.txt", "path_to_folder/asdief.txt"]

您可以在上面的代码中使用此列表。请注意提供文件夹的正确路径。 Python有一个当前的工作目录。路径需要相对于此目录。

查看os.getcwd（）以获取当前工作目录，并查看os.chdir（）以更改它。

修改

该文件是某些Web查询的结果。它说

内容类型：application / json

但当然json解析器将无法读取该文件。你没有包含程序的输出，但我认为json.load失败了。错误方法应该类似＆＃34;文件不包含有效的json＆＃34; 。那是因为你有（http？）的标题 - 包含在文件中的响应。他们需要被删除。你可以手动完成，你可以使用python，也许使用正则表达式。但最好的方法是不首先存储标题。你在哪里生成文件？我想你应该先调整一下这段代码。
老实说，我不认为你真的在努力解决这个问题。您只是粘贴了我的代码而没有反映您正在做的事情。阅读JSON，使用调试器并查看代码的每一行，考虑错误消息。

在.txt中查找变量并比较两个变量中的值？
