This article introduces the relevant knowledge of "Python Chinese problem example Analysis". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Before we do that, we need to understand that there are two types of strings in Python: a normal string (each character is represented by 8 bits) and an Unicode string (each character is represented by one or more bytes).

They can be converted into each other and have a more comprehensive description, so I won't say anything more here. Take a look at the following code:

#-*-coding:gb2312-*-# must be on the * line or the second line print "- code 1 -" a = "Chinese an I love you" print a print a.find ("I") b = a.replace ("love") "like") print b print "- code 2 -" x = "Chinese an I love you" y = unicode (x, "gb2312") print y.encode ("gb2312") print y.find (u "I") z = y.replace (u "love") U "like") print z.encode ("gb2312") print "- code 3 -" print y

Said that it encountered non-ASCII characters, and let's refer to pep-0263. PEP-0263 (Python Enhancement Proposal) makes it very clear that Python is also aware of the internationalization problem and proposes a solution. According to the above requirements of the proposal, we have the following code:

-code 1-Chinese an I love you 5 Chinese an I like you-code 2-Chinese an I love you 3 Chinese an I like you-code 3Murray- -Traceback (most recent call last): File "G:\ Downloads\ eclipse\ workspace\ p\ src\ hello.py" Line 16, in print y UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range

We can see that by introducing Python Chinese problem statement, we can use Chinese normally, and in code 1 and 2, the console can print out Chinese correctly. However, it is clear that the above code also reflects a number of problems:

1. Code 1 and 2 use different ways to use print. 1 is direct print, while 2 is encoded before print.

2. Code 1 and 2 look for the same character "I" in the same string, and the results are different (5 and 3, respectively)

3. There is an error when printing the unicode string y directly in code 3 (which is why it is encoded first in code 2).
