How To Replace Hashtags with HTML Anchor in Python/Django?

message = "@me this is nice. @you: let me #help you. #anyone> #Python, #All."

message.split() gives "

['@me', 'this', 'is', 'nice.', '@you:', 'let', 'me', '#help', 'you.', '#anyone>', '#Python,', '#All.']

But what I want is

['@me', 'this', 'is', 'nice.', '@you', 'let', 'me', '#help', 'you.', '#anyone', '#Python', '#All']. Without the :, ., > or any other symbol. I just want words alone.

startswith('#') should return

['#help', '#anyone', '#Python', #All] and the hashtag_links will then return

["<a href='hashtags\help'>#help</a>", "<a href='hashtags\anyone'>#anyone</a>", ...]

What I want to do is to be able to replace hashtags in message with their equivalent in hashtag_links so that they can be clickable when rendered in HTML.

You can do this quite easily with list comprehensions:

mylist = [i.rstrip(":;") for i in message.split() if i] # remove blanks
hashtagged = [i for i in mylist if i.startswith("#")]
