Saving an extra indent and the ':\n' makes it quite a bit easier for me to
read and understand in the long run. I find:
for x in range(10):
if not x % 2:
print "Another even number:",
print x
...
print "Finished processing the even number"
a lot harder to read and understand than:
for x in range(10):
if x % 2:
continue
print "Another even number:",
print x
...
print "Finished processing the even number"
because with the latter it's much more obvious for me how the flow of control
in the indented block is structured (and to what part of the loop the
condition applies, namely to the whole loop body). That's why I'd prefer
the "combination" of the two as:
for x in range(10) if not x % 2:
print "Another even number:",
print x
...
print "Finished processing the even number"
because the logic is immediately obvious (at least if you find the logic to be
obvious when reading list comprehensions, simply because the format is
similar), and there's no extra indentation (as in your example), which makes
the block, as I said, a lot easier to parse for my brain.
But, probably, that's personal preference.
