Tl;dr: Join strings together with exactly one space between non-blank text where they join.
I propose a meaning for s1 & s2 where s1 and s2 are strings. Namely, that it should be equivalent to s1.rstrip() + (' ' if (s1.strip() and s2.strip()) else '') + s2.lstrip() Informally, this will join the two strings together with exactly one space between the last non-blank text in s1 and the first non-blank text in s2. Example: " bar " & " foo " == " bar foo "
I don't find these semantics particularly intuitive. Python already has the + operator for concatenating strings and this doesn't apply any stripping. If you're emphasizing on joining words with single space delimiters, then the usual: def join_words(list_of_words) return ' '.join([x.strip() for x in list_of_words]) works much better. You can also apply this recursively, if needed, or add support for list_of_phrases (first splitting these into a list_of_words). The advantage of join_words() is that it's easy to understand and applies stripping in a concise way. I use such helpers all the time. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Experts (#1, Mar 06 2023)
