python re.sub - alternative replacement patterns

Question

I want to provide alternative replacement patterns to re.sub.

Let\'s say i\'ve got two search patterns as alternatives, like this:

re.sub(r\"[A-Z]+|[         


        

Answer 1

Usually, you would just use two replacements:

re.sub(r"[A-Z]+", replacement1, string)
re.sub(r"[a-z]+", replacement2, string)

Anticlimactic, right?

It's actually less code than the alternatives usually, and it's far clearer what you're doing.
