Yeah. Performance is noticeably faster. Fine for me From https://stackoverflow.com/questions/6610606/is-there-a-difference-between-using-a-dict-literal-and-a-dict-constructor Literal is much faster, since it uses optimized BUILD_MAP and STORE_MAP opcodes rather than generic CALL_FUNCTION: ``` python2.7 -m timeit "d = dict(a=1, b=2, c=3, d=4, e=5)" 1000000 loops, best of 3: 0.958 usec per loop python2.7 -m timeit "d = {'a':1, 'b':2, 'c':3, 'd':4, 'e':5}" 1000000 loops, best of 3: 0.479 usec per loop python3.2 -m timeit "d = dict(a=1, b=2, c=3, d=4, e=5)" 1000000 loops, best of 3: 0.975 usec per loop python3.2 -m timeit "d = {'a':1, 'b':2, 'c':3, 'd':4, 'e':5}" 1000000 loops, best of 3: 0.409 usec per loop ``` -- This is an automated message from the Apache Git Service.
