I wrote the below code

    esc = ((autoescape and conditional_escape) or (lambda x: x))
    def replace(matchobj):
        return ('&nbsp;%s' % matchobj.group(1))
    value = END_PUNCTUATION_WIDONT_REGEXP.sub(replace, esc(smart_text(value)))
    value = WIDONT_REGEXP.sub(replace, value)
    value = DOUBLE_SPACE_PUNCTUATION_WIDONT_REGEXP.sub(replace, value)
    return mark_safe(value)

What's a good function header?

Here's a good function header?
