Faster in terms of execution speed?
Sure just miss out the test...
accessing a key that does not exist will
through an exception, which is just as tiresome...
Tiresom
Looks like a simple 'in' is faster both when it's there...
>>> Timer("'D' in {'D':123}.keys()").timeit()
0.93669924584355613
>>> Timer("'D' in {'D':123}").timeit()
0.34678047105990117
... and when it isn't...
>>> Timer("'E' in {'D':123}.keys()").timeit()
0.99194670371434768
>>> Timer("'E'

Hi,
Till now, when I receive a dictionary that I'm not sure contains a
certain key, I would use the following template to access a given key:
if 'someKey' in dict.keys():
someData = dict['someKey']
is there a faster way to do this?
Looks l
