python traversing strings (including Chinese characters) detailed examples

s = "中国china"
for j in s:
  print j

First of all, what is the encoding of your 'a'? It may not be what you think gbk

>>> a='中国'
>>> a

Try this. If it comes out with 6 words, it means it is utf-8. If it comes out with 4 words, it means gbk.

In addition, whether it is utf-8 or gbk, it cannot be traversed in this way, because it will be taken out word by word here. The virtual machine treats a as a string with a length of len(a).

The next step is the traversal problem.

Most Linux shells default to utf-8, so one Chinese character is three words, so you have to read it three by three. You can try:

>>> a[:3]

Come out It's just a "中" character

The default command of windows is cp936, which is gbk. One Chinese character is two characters, so two characters are read two characters (a[:2] ).

There is another way to traverse, convert the string into unicode, so that both Chinese and English are one word, and you can use your for i in a method to traverse. The advantage of this is that Chinese and English characters are all one word, while in utf-8 and gbk, English letters only occupy one word.

s = u"中国china"
for j in s:
  print j

The output is as follows:

中
国
c
h
i
n
a
