This article mainly explains "how to use Chinese in Python". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to use Chinese in Python".

Using Chinese in Python

It has two default strings: str and unicode. When using it, you must pay attention to the difference between "Unicode string" and "unicode object". All subsequent "unicode strings" refer to "unicode objects" in python.

In fact, there is no such thing as "Unicode string" in Python, only "unicode" object. A traditional unicode string can be represented by a str object. It's just that at this time it's just a byte stream, and it doesn't have any practical meaning unless it's decoded to a unicode object.

We use "" to test on multiple platforms, and the different codes corresponding to "" are:

1. UNICODE (UTF8-16), C854; 2. UTF-8, E59388; 3. GBK, B9FE.

Windows console

The following is the result of running on the windows console:

You can see that in the console, the encoding of Chinese characters is GBK rather than UTF-16. After decoding the string s (GBK encoding) with decode, you get the equivalent unicode object.

Note: just because ss can be printed on the console does not mean it can be serialized directly, such as:

Outputting ss directly to a file throws the same exception. When dealing with a string in unicode, you must first call the encode function on it and convert it to other encoded output. This is the same for all environments.

Summary: in Python, a "str" object is a byte array, and it doesn't matter whether the contents are a legal string or what encoding the string uses (gbk, utf-8, unicode).

These contents need to be recorded and judged by the user. These restrictions also apply to "unicode" objects. Keep in mind that the content of the "unicode" object is definitely not necessarily a legal unicode string, as we'll see soon.

Summary: gbk-encoded str objects and unicode-encoded unicode objects are supported on the windows console.

Windows IDLE (running on Shell)

In IDLE under windows, the running effect is not exactly the same as that of the windows console:

As you can see, for strings that are not identified by "u", IDLE encodes the Chinese characters in GBK. But for the use of "u" unicode string, IDLE is also using GBK encoding, the difference is that every character is a unicode (object) character! At this point len (ss) = 4. This creates a magical problem that the current ss does not display properly in IDLE. And I have no way to convert ss into normal coding!

For example, use the following methods:

This may be because the localization of IDLE is not good enough and there is a problem with the support for Chinese. It is recommended that you do not use u "Chinese" in IDLE's SHELL, because what you want is not what you want.

This also shows that IDLE's Shell supports two formats of Chinese strings: GBK-encoded "str" objects and UNICODE-encoded unicode objects.
