JSON and Pickle modules

The results of #json module output are JSON strings that can be recognized by other languages
Import JSON
A = {' name ': ' Alex '}    #------->{"name": "Alex"}-----------> ' {"name": "Alex"} '
b = 9  #----------> ' 9 '
c = ' Hello ' #--------> "Hello"---------> ' "Hello"
D = [11,22] #------' [11,22] '

Print (Json.dumps (a))  #将对象封装成json字符串
A = {' name ': ' Liuhaiquan '}
A_j = Json.dumps (a)
With open (' a.txt ', ' r+ ') as F_read:
    F_read.write (A_j)

With open (' A.txt ', ' R ') as F_read:
    data = F_read.read ()
    Print (json.loads (data))    #提取字符串内的字典
    Print (Type json.loads (data))
------------------------------------------

#pickle的用法和json一样, but the result of pickle.dumps () processing is byte bytes
   Need to use RB when reading bytes

But pickle supports more data types, usually JSON uses more
