title: splitting merged words in python
body: <p>I am working with a text where all "\n"s have been deleted (which merges two words into one, like "I like bananasAnd this is a new line.And another one.") What I would like to do now is tell Python to look for combinations of a small letter followed by capital letter/punctuation followed by capital letter and insert a whitespace.</p>
  
  <p>I thought this would be easy with reg. expressions, but it is not - I couldnt find an "insert" function or anything, and the string commands seem not to be helpful either. How do I do this?
  Any help would be greatly appreciated, I am despairing over here...</p>
  
  <p>Thanks, patrick</p>
