Re: [Tutor] can't see emacs timer in action
Hello Max, the problem with running in a dos console terminal is that I have to switch back and forth from terminal and my xemacs. and I found that in windows dos console we have to specify buffer page. I do need a dynamic buffer control so I don't need to specify the buffer if my program run big things.

Re: [Tutor] can't see emacs timer in action
Hello Alan, thanks for the advice, but I don't understand why xemacs doesn't fix C-c C-c so we don't have to do such many things. in fact C-c C-c is fail to represent the well 'run' behaviour of python ? It would be nice to people who use python get the same benefit of typing C-c C-c and get the result it supposed to have in other languages. pujo On 6/16/05, Alan G <[EMAIL PROTECTED]> wrote: > > buffer/output pane before running my program, so I always do > > this to start my program: > > ... > > ...6 steps listed > > ... > > > This is one cycle of running. > > Is that normal ??? > > I doubt it, I've never user python mode in emacs but I have > used SQL and C++ modes and usually you just call C-c C-c from > the code window and the rest all happens magically. > > But even if you do have to do all of that the sionple solution > is to record it as a macro > > C-x ( > keys to press here > C-x ) > > You can execute it again with > > C-x e > > And you can save it so that it will be available next time > you start emacs.

With Python 2.4:
>>> l= [ [1], [2,3], [4,5], [6]]
>>> 2 in (i[0] for i in l)
True
>>> 3 in (i[0] for i in l)
False
with Python 2.3 use [i[0] for i in l] instead which is a little less efficient.

I would use 'value' in list rather than list.count('value') because it will
stop when it finds 'value'; list.count() will always inspect the whole list.

And once you have the columns, you can use a list comprehension to get the lengths of the elements and find the max. eg: >>> arr = [['a'*random.randint(1, 10) for i in range(5)] for j in range(10)] >>> pprint.pprint(arr) [['aa', 'a', 'aa', '', ''], ['aaa', 'aa', 'aa', 'aaa', 'aaa'], ['aa', 'aaa', '', 'aa', 'aaa'], ['', 'aa', 'aa', 'aa', 'aa'], ['aa', 'a', 'aa', 'a', ''], ['aaa', 'a', 'aa', 'a', 'aa'], ['', 'a', 'a', '', 'aa'], ['a', 'aaa', 'a', 'aa', 'aaa'], ['', 'aa', 'aa', 'a', 'a'], ['a', 'aa', 'aa', 'aaa', 'aa']] >>> [max([len(s) for s in l]) for l in zip(*arr)] [10, 9, 10, 6, 10] HTH! -- John. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
