It would be convenient if instead of:
hdlr = logging.StreamHandler()
hglr.setLevel(logging.DEBUG)
root.addHandler(hdlr)
it would be possible to write:
root.addHandler(logging.StreamHandler().setLevel(logging.DEBUG))

-1. Attribute setters or mutating methods returning self is not a common pattern in Python. See list.sort(). |

List is a standard type and it have None returned for a reson. Logging is a library with its own semantic and high level object. Here you don't need to return None to explicitly say that the object was modified in place. |

Well, can you find any other setter method of a "high level object" in the stdlib that returns self? |

Well, I can remember any other widely used high level objects from stdlib either. HTTP servers perhaps, but they are in a poor state. |

Well, there is argparse, but it doesn't support method chaining. Whatever, it is just a proposal. If consistency inside stdlib covers calling conventions for bundled user-level libs - I am fine with that. |

I agree with Georg. Besides, as far as possible, the API should be consistent across versions of Python, unless something is needed to take advantage of added features. With your proposal, users could write library code which then would not work in older Python versions - and that's not something we want to encourage. |
