Python get a paragraph from a text

I'm new to Python and I'm still learning about regular expressions. I want to get a paragraph between two key words; something like this:

Beginning of the text

Keyword1

Paragraph content

Keyword2

End of the text

How could I do it? I've tried this:

(?i)Keyword1(.*?)((?i)Keyword2Variant1|(?i)Keyword2Variant2)

But it doesn't really work.

You need to make sure the single dot also matches newlines: use the re.DOTALL flag.

Slightly modified from your (non-workable) example:

text = """
Keyword1

Paragraph content

Keyword2Variant2
"""

import re

pattern = 'Keyword1(.*?)(Keyword2Variant1|Keyword2Variant2)'
match = re.search(pattern, text, re.IGNORECASE|re.DOTALL)
print(match.group(1))

yields

Paragraph content

(two blank lines before and after, but the rendering makes them hardly visible.)
