如何提取“you attent at the”后面的字符串？你知道吗

"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

尝试使用正则表达式：

>>> 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)?'
>>> 

或使用：

>>> 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 2

你可以使用正则表达式：

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

你会在唯一的比赛中追上唯一的一组。你知道吗

Answer 3

我们可以在这里尝试使用split作为非regex选项：

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)
