Question

I have a string like:

" This is such an nice artwork"

and I have a tag_list ["art","paint"]

Basically, I want to write a function which accepts this string and taglist as inputs
and returns me the word “artwork” as artwork contains the word art which is in taglist.

How do i do this most efficiently?

I want this to be efficient in terms of speed

 def prefix_match(string, taglist):
        # do something here
     return word_in string

Answer 1

Try the following:

def prefix_match(sentence, taglist):
    taglist = tuple(taglist)
    for word in sentence.split():
        if word.startswith(taglist):
            return word

This works because str.startswith() can accept a tuple of prefixes as an argument.

Note that I renamed string to sentence so there isn’t any ambiguity with the string module.
