String slugification in Python

Question

I am in search of the best way to \"slugify\" string what \"slug\" is, and my current solution is based on this recipe

I have changed it a little bit to:

<         


        

Answer 1

You might consider changing the last line to

slug=re.sub(r'--+',r'-',slug)

since the pattern [-]+ is no different than -+, and you don't really care about matching just one hyphen, only two or more.

But, of course, this is quite minor.
