>>> f = open('1.txt','w')>>> f.write(u'叉叉')Traceback (most recent call last):  File "
      
       ", line 1, in 
       
        UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal 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 "
      
       ", line 1, in
