The processing of JSON in PYTHON27 to Chinese

The application scenario is as follows: Download data from the API, JSON parsing, storing in a dictionary, saving regularly. The restart program needs to load the saved text.

The problem 1:json are all Unicode strings, which are stored in the text \u***

Workaround: Turn off the ENSURE_ASCII switch

Json.dump (Pub.listdata,fp,ensure_ascii=false)

Issue 2: Number of dictionary keywords, changed from text load to Unicode string

Solve:

Go a little detour, the online solution, are converted, the string back to Utf-8, the method is

def byteify (input):

If isinstance (input, dict):

return {byteify (key): Byteify (value) for Key,value in Input.iteritems ()}

Elif isinstance (Input, list):

return [Byteify (element) for element in input]

Elif isinstance (Input, Unicode):

Return Input.encode (' Utf-8 ')

Else

return input

But it turns out that JSON is all about Unicode, and it turns around.

The final workaround is to use Unicode, but after load, add a handle to convert the key to a numeric value.

Pub.listdata=json.load (FP)
Pub.listdata={int (k): V for K,v in Pub.listData.items ()}

Issue 3: Coding issues

Solve:

By default, viewing with Sys.getdefaultencoding () is Utf-8

Decode (Code): Convert code to Unicode

Encode (code): Convert Unicode to code

If you call encode on a string in a non-Unicode format, the default encoding is converted to Unicode and then encode. System default encoding is ASCII, so error often

Set the default encoding:

Create a new sitecustomize.py in the Python lib\site-packages folder, with the following content:

# Encoding=utf8

Import Sys

Reload (SYS)

Sys.setdefaultencoding (' UTF8 ')
