Hi,
just to add another possible approach, you can use regular expression
search for this task, e.g.
(after you have read the text content to an input string):

>>> import re
>>> input_txt ="""1, 2, 3, 4
... #keyword1
... 3, 4, 5, 6
... 2, 3, 4, 5
... #keyword2
... 4, 5, 6 ,7"""
>>> re.findall(r"(?s)(#keyword1)(.*?)(#keyword2)", input_txt)
[('#keyword1', '\n3, 4, 5, 6\n2, 3, 4, 5\n', '#keyword2')]
>>>

like in the other approaches, you might need to specify the details
for specific cases (no keywords, only one of them, repeated keywords
(possible in different order, overlapping or "crossed"), handling of
newlines etc.

hth,
