| http://docs.python.org/dev/library/reprlib.html """ Formatting methods for specific types are implemented as methods with a name based on the type name. In the method name, TYPE is replaced by string.join(string.split(type(obj).__name__, '_')). Dispatch to these methods is handled by repr1(). Type-specific methods which need to recursively format a value should call self.repr1(subobj, level - 1). """ Outstanding. |

| Patch. Though I ponder whether the expression in question might be equivalent to simply: type(obj).__name__.replace('_', ' ') |

| Yes. Yes it would. In my opinion, it really shouldn't do this sort of name mangling, as it's a terrible idea, but whatever. |

| The documentation is just flat out wrong, actually: if ' ' in typename: parts = typename.split() typename = '_'.join(parts) The documentation is claiming the inverse. I don't know why we would ever have a space in a typename, ever (and if someone does awful hacks to get to that state, he should probably also do awful hacks to make reprlib work properly). It would be for the best if we could just remove this brain damage, but whatever. |

| Updated patch. I concur that anyone creating a type whose name has whitespace in it is just asking for trouble. |

| > I don't know why we would ever have a space in a typename, ever (and if someone does awful hacks to get to that state, he should probably also do awful hacks to make reprlib work properly). That part of the code has been added 22 years ago: https://hg.python.org/cpython/rev/a0d4c5ef1d5d#l9.22 So probably the reason is that the code is just old. Thanks for the patch, Chris! |
