如何搜索文本文件的文件夹以查看是否存在特定字符串，然后使用Python提取两个单词之间的字符串？

Question

Currently, I'm just trying to figure out why this code won't work.

EDIT: wrote some new code

EDIT 2: SOLVED (reading through comments reminded me to encode the with.open() so it looks like this now,

EDIT 3: New code for pulling the "string" (date) I need between two words.

import os
items=os.listdir("C:/output")


for names in items:
  if names.endswith(".txt"):
    with open('C:/output/' + names, encoding="utf8") as currentFile:
      text = currentFile.read()
      if ('Date Released' in text):
           a = 'Released'
           b = 'Description'
           startpos = text.find(a) + len(a)
           endpos = text.find(b, startpos)
           print('Date Released ' + text[startpos:endpos] + names + '\n')
           #print ('Found in ' + names[:-4] + '\n')
      else:
          print ('Not in ' + names[:-4] + '\n')

I'm now getting the output:

Date Released :  12/14/2016



1393-004IP_ B_ C2  filename

Date Released :  4/11/2017



1476-002 IP, filename

Date Released :  9/25/2015



1987-XXX IP filename

Is there a way to get the Date Released : #/##/#### line on the same line as the file name? Also, some output I get when I run this right now is garbage. I'm assuming it could be from checking for Date Released more than once or a possible flaw with the if condition?

如果您使用的是Windows，请尝试在路径名中使用双“ \\”而不是单“ /”
