I just read the PEP368 and really liked the proposed idea, sound like a great battery addition to include in the std lib: http://www.python.org/dev/peps/pep-0368/ One question/idea though: The proposed iterator will iterate over all pixels in a line, but only one line. The example code looks like this: # iterate over an image for line in rgb_image: for pixel in line: # swap red and blue, and set green to 0 pixel.value = pixel.b, 0, pixel.r But, wouldn't it be more Pythonic and simpler to have an iterator that iterates over all pixels in an image? Starting with upper left corner and moving left-right and (line by line) to lower right. This would change the code above to: for pixel in rgb_image: # swap red and blue, and set green to 0 pixel.value = pixel.b, 0, pixel.r The idea I'm having is that fundamentally the image is made up of a 2D array of pixels, not rows of pixels. And having the iterator focus on pixels instead make then more sense, no? Or if possible have two iterators. Otherwise, big thumbs up for PEP 368 as well as having PEP:s for driving the language development process in an orderly and well documented way. - -- Med vänlig hälsning, Yours Joachim Strömbergson - Alltid i harmonisk svängning. ======================================================================== Kryptoblog - IT-säkerhet på svenska http://www.strombergson.com/kryptoblog ======================================================================== -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkpMcIQACgkQZoPr8HT30QFkcgCgzxb9JS2l87B/nkpf05FLDjY5 RPQAni2yPxKjCd4lM/qMBNhjp8HHg/PZ =9gB/ -----END PGP SIGNATURE----- -- http://mail.python.org/mailman/listinfo/python-list
