  • Python Success Stories

    Python Success Stories First published in Linux Journal, May 2000. Copyright 2000 Specialized Systems Consultants, Inc. All rights reserved. Introduction My first look at Python was an accident, and I didn't much like what I saw at the time. It was early 1997, and Mark Lutz's book Programming Python from O'Reilly & Associates had recently come out. O'Reilly books occasionally land on my doorstep, selected from among the new releases by some mysterious benefactor inside the organization u...

  • PEP 672 -- Unicode-related Security Considerations for Python

    ...Python identifier, not a string. The East Asian word for ten looks like a plus sign, so 十= 10 is a complete Python statement. (The “十” is a word: “ten” rather than “10”.) Note The converse also applies – some symbols look like letters – but since Python does not allow arbitrary symbols in identifiers, this is not an issue. Confusable Digits Numeric literals in Python only use the ASCII digits 0-9 (and non-digits such as . or e). However, when numbers are converted from strings, such as in ...

  • PEP 285 -- Adding a bool type

    ...Python. When showing people comparison operators etc. in the interactive shell, I think this is a bit ugly: >>> a = 13 >>> b = 12 >>> a > b 1 >>> If this was: >>> a > b True >>> it would require a millisecond less thinking each time a 0 or 1 was printed. There's also the issue (which I've seen baffling even experienced Pythonistas who had been away from the language for a while) that if you see: >>> cmp(a, b) 1 >>&g...
