If we run 2to3 on the following code: s = b' ' print s[0] == s we end up with this: s = b' ' print(s[0] == s) However, the first code, under python2 prints True while the converted code, under python3 prints False. Shouldn't 2to3 convert this code to: s = b' ' print s[0:1] == s instead? |

2to3 can't guess which slices are from bytes. |

Replacing string indexes with length-1 slices in the 2.x codebase, whether or not one one is running 2to3, seems to be a 'known' technique for Python3 portability and unicode-bytes inter-operability. (It was discussed this week on py-dev list .) But I do not see it mentioned in PyWiki, such as on http://wiki.python.org/moin/PortingPythonToPy3k |
