Retrieve the last 3 words of a string using regex [duplicate]

Question

I'm trying to retrieve the last 3 words of a string using regex.

The string - "From the place on July 19, 2019"

I need to extract only the date part 'July 19,2019'.

I tried the below ways :-

(\w{3})$             # gives last 3 letters of the last word
([,0-9]{3})$         # gives last 3 digits from the last word
(?:\w+\s*){1,3}$     # retrieves only the last word

None of them gives me the last 3 words.

Answer 1

Try this:

string = "From the place on July 19, 2019"
mobj = re.search(r"\b(\w+(?=\s\d+,)\s\d+,\s?\d+)", string)
date = mobj.group(1)

Output:

>>> print(date)
July 19, 2019
