Insert hashtags in python string

I try to insert '#' in front of specific words in a sentence with an elegant solution (not a big function with many 'if').

hashwords = ['Google','Apple','Titan','Facebook']

input = 'Google,Apple, Titan and Facebook. Not Facebook@Work OpenTitan or apple.'

output = '#Google,#Apple, #Titan and #Facebook. Not Facebook@Work, OpenTitan or apple.'

I tried things like that, but I would like to take into account the punctuation or words that can be part of bigger words :

    for elem in hashwords :
        if elem in input:
            input = input.replace(elem, '#'+elem)

Any idea?

Thanks

import re

hashwords = ['Google','Apple','Titan','Facebook']
input = 'Google,Apple, Titan and Facebook. Not Facebook@Work OpenTitan or apple.'

for elem in hashwords :
    input = re.sub(r'\b'+elem+r'\b(?!@)', '#'+elem, input)
print(input)

Output:

#Google,#Apple, #Titan and #Facebook. Not Facebook@Work OpenTitan or apple.

You can use r'(?<!@)\b'+elem+r'\b(?!@)' if you don't want Apple@Titan to be matched.
