How do I replace whitespaces with underscore?

Question

I want to replace whitespace with underscore in a string to create nice URLs. So that for example:

\"This should be connected\" becomes \"This_should_be_conn         


        

Answer 1

Django has a 'slugify' function which does this, as well as other URL-friendly optimisations. It's hidden away in the defaultfilters module.

>>> from django.template.defaultfilters import slugify
>>> slugify("This should be connected")

this-should-be-connected

This isn't exactly the output you asked for, but IMO it's better for use in URLs.
