Python method to get the middle string based on the beginning and end strings _python

This example describes how Python obtains an intermediate string based on the beginning and end strings. Share to everyone for your reference. The specific analysis is as follows:

This gives a string that specifies the beginning and end of the string, and returns the string of the middle folder, for example:
Content:<div class= "a" >jb51.net</div>
Startstr:<div class= "a" >
Endstr:</div>
return Result: jb51.net

def getmiddlestr (content,startstr,endstr):
  startIndex = Content.index (startstr)
  if startindex>=0:
    StartIndex + = Len (startstr)
  endindex = Content.index (endstr) return
  Content[startindex:endindex]
if __ name__== ' __main__ ':
  print (Getmiddlestr (' <div class= "a" >jb51.net</div> ', ' <div class= "a" > ', ' </div> '))
