I have written chunks of Python code that look this:
new_array = []
for a in array:
if not len( a ):
continue
new_array.append( a )
and...
string = ""
for r in results:
if not r.startswith( '#' ):
string =+ r
It seems that a list comprehension could clean up the code, but I seem
to have a mental block on list comprehensions. I've read up a lot on
this subject in my books and on the Internet and for whatever reason,
I'm having problems with this idiom (if that's the correct expression).
I've made a number of attempts to solve this on my own but I keep
getting errors.
Could someone please tell me how I could convert the above code to
something more elegant but readily understandable?
Finally, if someone could point me to a good tutorial or explain list
compressions I would be forever in your debt.
