.join() question

[Simon Bayling]

I would risk a guess that this comes under the "explicit is better than 
implicit" guideline.

''.join([str(i) for i in lst])

Explains to everyone that you know the list has some non-string things, 
and you intend them to be str()'ified.

Intention-guessingly yours,
Simon.
