What is the pythonic way to split a string before the occurrences of a given set of characters?

Edit: It should also split single occurrences, i.e. from 'ABC'...

I have an ugly solution that works: explode the search string into an array of words, look up each w...

So when I tried the following C# code I was shocked: Regex rgx = new Regex("."); if (rgx.Match("\r\n").Success) MessageBox.Show("There is something rotten in ...
