Here's a simple example of using Python to parse JSON:
Copy Code code as follows:
#!/usr/bin/
Skipkeys, which defaults to false. The Dumps method stores Dict objects when key must be of type STR, other types cause typeerror exceptions, and if the Skipkeys is set to true the illegal keys are filtered gracefully.
data = {' B ': 789, ' C ': 456, (): 123} print ' original data: ', repr (data) print ' JSON encoded ', Json.dumps (data,skipkeys= True)
Output:
Original data: {(1, 2): 123, ' C ': 456, ' B ': 789}
, which is actually a tuple (item_separator, Dict_separator), is the default (', ', ': '), which means that there is a "," separation between keys in dictionary, The key and value are separated by ":".
encoding: The default is UTF-8, which sets how JSON data is encoded.
Sort_keys: Sorts the data according to the value of keys.
The decode process is a process of converting a JSON object into a

I tried it. The JSON string needs to be key-added.For example: {name: "AAA", value: 1} Here, name and value are keys, and an error is reported during conversion.To be written{"Name": "AAA", "value": 1}
This is the second metho
stores the Dict object, and other types can cause the TypeError exception to be created and gracefully filter the illegal keys if the Skipkeys is set to true.
data = {' B ': 789, ' C ': 456, (1,2): 123}
print ' original data: ', repr (data)
print ' JSON encoded ', json.dumps (data, Skipkeys=true)
Output:
Original data: {(1, 2): 123, ' C ': 456, ' B ': 789}
JSON encoded {"C": 456, "

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.
Python has its own module for handling python, which can be directly import JSON when used. Using the loads method, you can convert a JSON string into a Python object, as follows:JSON PythonObject DictArray listString UnicodeNumbe
# # 0x00 introduction:If we are going to pass objects between different programming languages, we have to serialize the object into a standard format, such as xml, but the better way is to serialize it to json, because JSON represents a string that can be read by all languages, easily stored to disk, or transmitted over a Network.
JSON is a lightweight data interchange format with good support in all languages. A dictionary is a data structure of Python. Can be considered an associative array.
Sometimes we need to design a dictionary to convert to JSON serialization to a file, or read JSON from a fil
