Python：按字符位置拆分字符串

Question

How can I split a string by the position of a word?

My data looks like this:

test = 'annamarypeterson, Guest Relations Manager, responded to this reviewResponded 1 week agoDear LoreLoreLore,Greetings from Amsterdam!We have received your wonderful comments and wanted to thank you for sharing your positive experience with us. We are so thankful that you have selected the Andaz Amsterdam for your special all-girls weekend getaway. Please come and see us again in the near future and let our team pamper you and your girlfriends!!Thanks again!Anna MaryAndaz Amsterdam -Guest RelationsReport response as inappropriateThank you. We appreciate your input.This response is the subjective opinion of the management representative'

I need this output:

responder = 'annamarypeterson, Guest relations Manager'
date = 'Responded 1 week ago'
response = 'Dear ....' #without 'This response is the subjective opinion of the management representative'

I know that the find.() function gives the position of a word, and I want to use this position to tell Python where to split it. For example:

splitat = test.find('ago')+3

What function can I use to split with an integer? The split() function does not work with an int.

Answer 1

You can do this with strings (and lists) using slicing:

str = "hello world!"
splitat = 4
l, r = str[:splitat], str[splitat:]

will result in:

>>> l
hell
>>> r
o world!

Answer 2

Maybe the simplest solution is to use string slicing:

test = 'annamarypeterson, Guest Relations Manager, responded to this reviewResponded 1 week agoDear LoreLoreLore,Greetings from Amsterdam!We have received your wonderful comments and wanted to thank you for sharing your positive experience with us.

pos = test.find('ago') + 3
print(test[:pos], test[pos:])

Answer 3

Got a built in function for you.

import re    
test = 'annamarypeterson, Guest Relations Manager, responded to this reviewResponded 1 week agoDear LoreLoreLore,Greetings from Amsterdam!We have received your wonderful comments and wanted to thank you for sharing your positive experience with us. We are so thankful that you have selected the Andaz Amsterdam for your special all-girls weekend getaway.

We appreciate your input.This response is the subjective opinion of the management representative'

m = re.search('ago', test)
response = test[m.end():]

This is the object produced by regex: <re.Match object; span=(41, 44), match='ago'>

You can use m.start() to get the position of the first character and m.end() to get the last character.
