Question

如何在“您参加了”之后提取字符串？

"How satisfied, if at all, are you with the following stadium facilities at the Arabian Gulf League/Arabian Cup/Arabian Super Cup/President's Cup matches you attend at the Hazza bin Zayed Stadium (Al Ain)?"

Answer 1

We could try just using split here, for a non regex option:

inp = "How satisfied, if at all, are you with the following stadium facilities at the Arabian Gulf League/Arabian Cup/Arabian Super Cup/President's Cup matches you attend at the Hazza bin Zayed Stadium (Al Ain)?"
output = inp.split('you attend at the')[1]
print(output)

This prints:

Hazza bin Zayed Stadium (Al Ain)?

Answer 2

Try using regex:

>>> import re
>>> re.sub('.*you attend at the ', '', "How satisfied, if at all, are you with the following stadium facilities at the Arabian Gulf League/Arabian Cup/Arabian Super Cup/President's Cup matches you attend at the Hazza bin Zayed Stadium (Al Ain)?")
'Hazza bin Zayed Stadium (Al Ain)?'
>>> 

Or use:

>>> s = "How satisfied, if at all, are you with the following stadium facilities at the Arabian Gulf League/Arabian Cup/Arabian Super Cup/President's Cup matches you attend at the Hazza bin Zayed Stadium (Al Ain)?"
>>> s[s.find("you attend at the ") + 18:]
'Hazza bin Zayed Stadium (Al Ain)?'
>>> 

Answer 3

You could use regex:

(?:you attend at the )(.*)

You would be after the only group in the only match.
