JSON, Pickle

What does serialization mean?

Serialization refers to converting the data type in memory into a string so that it can be stored on the hard disk or transmitted to the network remotely, because the hard disk or the network can only accept bytes

Turns memory data into characters, called serialization

Convert character to memory data type, called deserialization

Import Json,pickle

JSON, used to convert between string and Python data types

data = {' name ': ' Rong '}

D = json.dumps (data) #直接将数据转成字符串

D2 = Json.loads (d) #直接将字符串转成数据类型

Json.dump (): Write to Hard disk

data = {' name ': ' Rong '}

f = open (' Test.json ')

Json.dump (data, F)

F.close ()

Json.load (): Read back from the file

Pickle, used for Python-specific types and Python data types for conversion

Import shelve
