Python 2和Python 3的主要区别

-*- coding: utf-8 -*-

1	-- coding: utf-8 --

因此对于Python 2的中文符需要编码（先转为Unicode再进行encode）

# Windows
my_words.decode("gb2312").encode("utf-8")
# Linux
my_words.decode("utf-8").encode("utf-8")

# Windows

my_words.decode("gb2312").encode("utf-8")

# Linux

my_words.decode("utf-8").encode("utf-8")

而Python中则直接采用了Unicode编码，无需进行转码

SyntaxError: Missing parentheses in call to ‘print’
在Python 3中print后需添加括号进行打印输出

NameError: name ‘xrange’ is not defined
Python 2下的xrange在Python 3中使用range

AttributeError: ‘dict’ object has no attribute ‘itermvalues’
Python 3对于原Python 2下的iteritems, iterkeys, itervalues一律去除iter
