我正在尝试创建一个代码，以从字符串列表中排除字符串中的某些关键字。今天早上在stackoverflow的帮助下，我可以添加可以排除包含特定关键字的某些字符串的代码。 Python: Remove the certain string from list if string includes certain keyword
但是，当我更改数据集时，它不起作用。
# -*- coding: utf-8 -*-
import nltk, json, os, csv, matplotlib, pylab, re
from matplotlib import *
from nltk import *
from pylab import *
from re import *
'Start with empty list'
tweets=[]
tweetsF=[]
for line in open('apple.json'):
try:
tweets.append(json.loads(line))
except:
pass
keywordFilter=['pie','juice','cinnamon']
for tweet in tweets:
for key, value in tweet.items():
if key=='text':
tweetsF.append(value)
print(tweetsF[:50])
original_list=tweetsF[:50]
tweetsFBK=[str for str in original_list if not any(word in str for word in keywordFilter)]
print (tweetsFBK)
从今天早上的代码到上面的代码，我只更改了 tweetsF 部分，它返回了数据源中的字符串列表。但是，我认为这不是一件容易的事，因为它是像今早一样的问题的字符串列表。
你知道为什么排除部分不会返回任何值（即返回0）。 ？

编辑：看到你的编辑，这可能无法解决你的问题。您可能仍希望整体解析json文件。
原始讯息：
您的输入文件apple.json如何？它可能是一个json文件，你不应该读取并解析它换行。而是尝试类似的事情：
with open('apple.json') as f:
jsonlist = json.loads(f.read())
for tweet in jsonlist:
#do things
你的代码中也有一些不好的做法。使用open('apple.json')你打开一个文件但没有关闭它（在这种情况下这不是太糟糕，因为它会在你的脚本到达时自动关闭，但如果你打开很多文件，这可能会导致问题。显式优于隐式）。
其次，您正在使用try: [...] except:来消除所有错误。错误通常是想告诉你一些事情，所以你想要处理它们或者让它们报告，这样你就可以对它们采取行动。如果您收到错误并且您100％确定可以忽略它们，请执行以下操作：
try:
stuff() #that might throw IndexError
except IndexError as e:
pass
#or deal with the error e.g. log

如果要从列表中删除所有字符串，如果它们有另一个列表中的一个或多个字符串？如果是的话：
#list of words/strings to remove
filter=['goto','echo','if']
#input list:
fileIn=['echo hello!','set pass=','if exist private_GONE goto _UNLOCK','if exist private goto _LOCK','if not exist private goto MKprivate']
#output lit:
fileOut=[]
for x in fileIn:
z=0
for y in filter:
if(not y in x):
z=z+1
if(z==len(filter)):
fileOut.append(x)
print('\n'.join(fileOut))
但是如果您只想从列表中删除字符串：
import re
#list of words/strings to remove
filter=['goto','echo','if']
#input list:
fileIn=['echo hello!','set pass=','if exist private_GONE goto _UNLOCK','if exist private goto _LOCK','if not exist private goto MKprivate']
#output lit:
fileOut=[]
for x in fileIn:
temp=x
for y in filter:
temp=re.sub(y,'',temp)
fileOut.append(temp)
print('\n'.join(fileOut))
