How can I match text that falls within specific parameters in Python?
Question:
I have a text file containing my TikTok video browsing data
It looks something like this:
Date: 2022-07-26 00:30:36
Video Link: https://www.tiktokv.com/share/video/7124308827599588614/
Date: 2022-07-26 00:30:31
Video Link: https://www.tiktokv.com/share/video/7124339950736166187/
Date: 2022-07-26 00:29:52
Video Link: https://www.tiktokv.com/share/video/7123899535344028933/
I want to write the Video Link that fall between 2022-07-22 & 2022-07-24 and write them to a new text file.
I know how to write data to text files; however, I do not know how I can only match those video links that fall within the dates I have specified.
How can I accomplish this?
Answers:
One approach would be to read the entire text file into a string, and then use re.findall to find all date/link pairs. Then, filter that list using a comprehension such that only dates within in your range are retained.
inp = """Date: 2022-07-22 00:30:36
Video Link: https://www.tiktokv.com/share/video/7124308827599588614/

matches = re.findall(r'Date: (d{4}-d{2}-d{2}).*?bVideo Link: (https?://.*?/)n', inp, flags=re.S)
keep = [x[1] for x in matches if x[0] in ['2022-07-22', '2022-07-23', '2022-07-24']]
print(keep)
# ['https://www.tiktokv.com/share/video/7124308827599588614/',
