For strings, len(x)>0 <=> len(x) <=> x, so the above statement is  
equivalent to:

list=filter(lambda x: x, list)

which according to the documentation is the same as:

list=filter(None, list)

which is the fastest variant AFAIK.

(Of course, it's even better to use the right split() call so there is no  
empty strings to filter out in the first place)
