JSON serialization for Python

　　

info = {
    "Name":"Roger",
    "Age":12
}

Open ("test.txt","W")
F.write (str (info))
F.close ()

Open ("test.txt","R")
data = F.read ()
Print (data["name"])
F.close ()
Will error

Use eval ()

Open ("test.txt","R")
data = F.read ()
Print (eval (data) ["name"])
F.close ()

In the form of JSON

Import JSON
info = {' name ':' Roger ',' age ':12}
Print (Json.dumps (info))
Open ("test.txt","W")
F.write (Json.dumps (info))

Import JSON
Open ("test.txt","R")
data = Json.loads (F.read ())
Print (data["age"])
F.close ()

One more example: pic

 import Pickle 
 def functest (): 
 pass 
 info = { ' name ':  Roger ' , ' Age ': 12, print (Pickle.dumps (info)) 
 F = open ( Span style= "COLOR: #6a8759" > "test.txt" , F.write (Pickle.dumps (info))            

 import Pickle 
 def functest (): 
 pass 
 F = open ( "test.txt" , "RB") 
 data = Pickle.loads (F.read ()) 
 print (Data[ "Age"]) 
 F.close ()          

One more example.
Import Pickle
Functest ():
    Pass
info = {' name ':' Roger ',' age ':+,' func ': Functest}
Print (Pickle.dumps (info))
Open ("test.txt","WB")
F.write (Pickle.dumps (info))

Import Pickle
Functest ():
    Print ("test")
Open ("test.txt","RB")
data = Pickle.loads (F.read ())
Print (data["func"] ())
F.close ()

The above can also be written in this:

Import Pickle
DefFunctest ():
    Pass
info = {' Name ':' Roger ',' Age ':12, ' func ': functest} 
 
 F = open ( "test.txt" ,< Span style= "COLOR: #6a8759" > "WB") 
 
 Pickle.dump (info,f) 
 
 F.close () 
 
 import Pickle 
 def  Functest (): 
 print ( "test") 
 F = open (" test.txt "  "RB") 
 data = Pickle.load (f) 
 print (Data[ "func"] ()) 
 F.close ()            
 
  remember: Dump once and load once.
