ReGex - Python - From word till the first dot in a sentencce

Question

text = "hello there. I would like to capture from this point till the end"
capture= re.findall(r'(point).$',text)
print (capture)

Can someone tell me what did I do wrong here? Thank you.

Did you mean `.*`? There isn't precisely one character between `point` and the end of the string. — jonrsharpe, Feb 27 '16 at 12:55
oh no no ~ I mean I wanna capture from the word point till the end of the sentence: "...point till the end" — D1W1TR15, Feb 27 '16 at 12:57
Yes, and unless that's precisely one character `.$` cannot match. — jonrsharpe, Feb 27 '16 at 13:04
oh yeah but it does not include "point" word though. So can I actually include that too with this code? — D1W1TR15, Feb 27 '16 at 13:08

Assuming you want to capture everything after a certain word till the next dot or the end of the string:

point(.*?)(?:\.|$)

Here, the (.*?) is a capturing group matching any characters 0 or more number of times in a non-greedy fashion. (?:\.|$) is a non-capturing group matching either a dot or an end of the string.

Demo:

>>> re.findall(r'point(.*?)(?:\.|$)', "hello there. I would like to capture from this point till the end")
[' till the end']
>>> re.findall(r'point(.*?)(?:\.|$)', "hello there. I would like to capture from this point till the end of the sentence. And now there is something else here.")
[' till the end of the sentence']
