How to grab strings AFTER matched string in python

I am an amateur using Python for some time. Sorry if this is a stupid question, but I was wondering if anyone knows an easy way to grab a bunch of lines if the input file format looks like this:

"Heading 1

Line 1

Line 2

Line 3

Heading 2

Line 1

Line 2

Line 3 "

I won’t know how many lines after each heading, but I want to grab them all. All I know is the name or regular expression pattern for the header.

The only way I know to read the file is the path "for the line in the file:", but I don’t know how to capture the lines AFTER which line I’m leading to now. Hope this makes sense and thanks for the help!

            if buffer: yield buffer
            buffer= [ line ]
        else:
            buffer.append( line )
    yield buffer

with open( "some_file", "r" ) as source:
    for heading_and_lines in group_by_heading( source ):
        heading= heading_and_lines[0]
        lines= heading_and_lines[1:]
        # process away.
