Python json serialization deserialization and Chinese Encoding
In a project, you need to obtain a json-format data from the cloud, save it to a local file, and then read it out. In this case, you need to use the json dumps method and loads method, to achieve data serialization and deserialization. Specifically, the dum
When using the command-Number output interface test results, it is found that it cannot be displayed in the desired JSON format. Find out more about Python's own powerful tools.Directly on the code:Import=="echo '%s ' | Python-m json.tool" % contentprint os.system (command)The result of the perfect output JSON format will no longer be copied to the online

python enables Excel to be converted to JSON
First, preparePython operates on Excel by relying on the two modules of xlrd and XLWT. XLRD is a module for reading Excel, XLWT for writing to Excel. Download: https://pypi.python.org/pypi/xlrd HTTPS://PYPI.PYTHON.ORG/PYPI/XLWT
If you just read Excel files, simply download xlrd

Python recursively queries the menu and converts it to a json instance, pythonjson
Recently, I need to write a menu in python, and it took two or three days to get it done. Now I want to record it here. You can use it for reference.

The json parsing function of the python standard library is used. loads is a json string that cannot be referenced using single quotes. for example, use double quotes instead, or call json before loads. dumps (a) is also acceptable.

The most extensive application of Json is the data format for the communication of Web servers and clients in AJAX .

Concept: serialization (serialization): Converts the state information of an object into a process that can be stored or transmitted over a network, in a format that can be json,xml, and so on. Deserialization is the state of the deserialized object that is read from the storage area (Json,xml) and re-created. JSON(Java Script Object Notation): A lightweight da
