中文输出

#-*-coding:utf8-*-

将unicode写入文本
一：

>>> f = open(\'1.txt\',\'w\')
>>> f.write(u\'叉叉\')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: \'ascii\' codec can\'t encode characters in position 0-1: ordin
al not in range(128)
>>> a = unicode.encode(u\'叉叉\',\'utf-8\')
>>> f.write(a)
>>> f.close()

二：

>>> import codecs
>>> f = codecs.open(\'1.txt\',\'w\')
>>> f.write(u\'叉叉\')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: \'ascii\' codec can\'t encode characters in position 0-1: ordin
al not in range(128)
>>> f = codecs.open(\'1.txt\',\'w\',\'utf-8\')
>>> f.write(u\'叉叉\')
>>> f.close()
