These playlists are similar enough that I think you could just combine the text contents, but strip out the first three tags from the second one to avoid duplicating them.

Here is some code to do that; it doesn't assume the number of tags to skip is 3.

import m3u8

# Read in the playlists
# playlist_1_text = ...
# playlist_2_text = ...

# Split them into lines
playlist_1_lines = playlist_1_text.splitlines()
playlist_2_lines = playlist_2_text.splitlines()

# Take the lines from playlist 1, then add in any non-duplicates from playlist 2
line_set = set(playlist_1_lines)
combined_lines = playlist_1_lines + [x for x in playlist_2_lines if x not in line_set]
playlist_combined_text = '\n'.join(combined_lines)

# Parse the combined lines to put the media tags back at the top
combined_playlist = m3u8.loads(playlist_combined_text)
combined_playlist_text = combined_playlist.dumps()
print(combined_playlist_text)

Thank you @bbayles

@Trungdo253 does the bbayle's snippet solve your problem?
