These names are defined by the interpreter and its implementation (including the standard library). Current system names are discussed in the Special method names section and elsewhere. More will likely be defined in future versions of Python. Any use of __*__ names, in any context, that does not follow explicitly documented use, is subject to breakage without warning. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Set Reply-To field to Tutor@python.org

Often this means that the archives are incomplete, so that there is a thread but the part of the thread where the OP says Thanks, this is the solution that worked or Sorry, that's not what I meant. My actual problem is... is missing. Not having this information on the list is unhelpful. It is unhelpful for people reading the archives in the future, for people who keep replying to a thread that is essentially solved, and for people who offer suggestions and don't get feedback on whether their suggestions were useful. For me at least, it is replying off-list that requires explicit consideration. The fact of giving and receiving help by a public mean, and having this help available to others as well, complete in the archives, it's for me enough reason to give +1 to set reply-to field to tutor address. If I am reading something which comes from a mailing list then I think the most proper way to reply would be to send an answer to all the people which originally received the same message. That way, I can avoid duplicate answers, even better this conduct can lead to additional complementary answers because someone can construct on previous partial solutions/suggestions. But this needs all answers are available to everyone. This is my opinion. I hope my writing is understandable. -- Jonatan G ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

I understand the list comprehension so far, but ran into a snag with the matrix. I've created the matrix M as follows: M = [[1, 2, 3[, [4, 5, 6], [7, 8, 9]] then ran through the various comprehension examples, including: diag = [M[i][i] for i in [0, 1, 2]] which, of course, gave me [1, 5, 9]. Then I tried creating revdiag, wanting to return [3, 5, 7], tried several different ways, never quite got what I was looking for, so I'm looking for guidance as I'm stuck on this idea. Here's the various attempts I made and the tracebacks: revdiag = [M[i][i] for i in [2, 1, 0]] revdiag [9, 5, 1] # once I saw the output, this one made sense to me. revdiag = [M[i][j] for i in [0, 1, 2] and for j in [2, 1, 0]] File stdin, line 1 revdiag = [M[i][j] for i in [0, 1, 2] and for j in [2, 1, 0]] ^ SyntaxError: invalid syntax revdiag = [M[i][j] for i in [0, 1, 2] and j in [2, 1, 0]] Traceback (most recent call last): File stdin, line 1, in module NameError: name 'j' is not defined revdiag = [M[i][j] for i in [0, 1, 2], for j in [2, 1, 0]] File stdin, line 1 revdiag = [M[i][j] for i in [0, 1, 2], for j in [2, 1, 0]] ^ SyntaxError: invalid syntax revdiag = [M[i][j] for i in [0, 1, 2], and for j in [2, 1, 0]] File stdin, line 1 revdiag = [M[i][j] for i in [0, 1, 2], and for j in [2, 1, 0]] ^ SyntaxError: invalid syntax The way you are trying to do it would be revdiag = [M[i][j] for i,j in [(0,2),(1,1),(2,0)]] ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
