Re: [Tutor] Problem with assigning list elements

That is not the expected behavior and not the behavior I see: Python 2.5.1 (r251:54863, May 1 2007, 13:27:01) [C] on sunos5 >>> z = [[1,2],[3,4]] >>> z[0][0]=100 >>> print z [[100, 2], [3, 4]] [EMAIL PROTECTED] wrote: > I'm having a problem assigning numbers to a 2-D list. > > for the 2d li

>>> t = timeit.Timer( '1000%2') >>> t.timeit(100) 0.25893402099609375 >>> t = timeit.Timer( '1000&1') >>> t.timeit(100) 0.2567589282989502 It's almost insignificantly faster. However as a programmer and a mathematician, I disagree with your position that the bitwise operation is mo

Re: [Tutor] Quick question

There are quite a few ways to do what you want. Here's are a few variations on a theme: try: if not any( ( len(queuePacket['procSeq']), len(queuePacket['opacSeq']), len(queuePacket['keySeq']) ) ): # Do your stuff here do_stuff() except KeyE
