#coding=utf-8

#-*- coding: utf-8 -*-

一直搞不清楚這倆頭什么區(qū)別。直覺上一樣。今天特意查了一下，大致明白了：

對于python解釋器來說，這兩種寫法一樣。但是對于編輯器來講，可能會出現(xiàn)識別問題。

Defining the Encoding

Python will default to ASCII as standard encoding if no otherencoding hints are given.To define a source code encoding, a magic comment mustbe placed into the source files either as first or secondline in the file, such as:# coding=<encoding name>or (using formats recognized by popular editors)#!/usr/bin/python# -*- coding: <encoding name> -*-or#!/usr/bin/python# vim: set fileencoding=<encoding name> :More precisely, the first or second line must match the regularexpression "coding[:=]\s*([-\w.]+)". The first group of thisexpression is then interpreted as encoding name. If the encodingis unknown to Python, an error is raised during compilation. Theremust not be any Python statement on the line that contains theencoding declaration.To aid with platforms such as Windows, which add Unicode BOM marksto the beginning of Unicode files, the UTF-8 signature'\xef\xbb\xbf' will be interpreted as 'utf-8' encoding as well(even if no magic encoding comment is given).If a source file uses both the UTF-8 BOM mark signature and amagic encoding comment, the only allowed encoding for the commentis 'utf-8'. Any other encoding will cause an error.
