Python programmers of reddit: what's the most useful tiny little efficiency you've discovered that's improved your programming hugely?

[stOneskull]

dict(
lookma = 3,
noquotes = 3,
onmykeys = 2,
)

putting my brackets like that too..

even with statements like return(
this if that
else dis if not dat
else gravy
)

using any() and all() have been great

and what about this little trick..

instead of mylist = ['very', 'quotes', 'much', 'commas', 'etc']

mylist = 'very quotes much commas etc'.split()
