一.json序列化

xml在被json取代，不同平臺之間的語言轉換，只能處理簡單的。復雜的用pickle；

pickle只能在python中用，而在Java中json也可以被識別。

info = {
    ‘name‘:‘xiaolaizi‘,
    ‘age‘:22
}
f = open("test.text","w")
f.write(str(info))
------------------------------------------------

import json
info = {
    ‘name‘:‘xiaolaizi‘,
    ‘age‘:22
}
f = open("test.text","w")
f.write(json.dumps(info))

 

---------------------------------------
import pickle
info = {
    ‘name‘:‘xiaomaizi‘,
    ‘age‘:22
}
f = open("test.text","wb")
f.write(pickle.dumps(info))
#等價pickle.dump(info,f)

f = open("test.text","r")
data = eval(f.read())
f.close()
print(data[‘age‘])     #反序列化
-------------------------------------------

import json
f = open("test.text","r")
data = json.loads(f.read())
f.close()
print(data[‘age‘])

--------------------------------------------

import pickle
f = open("test.text","rb")
data = pickle.loads(f.read())
#data = pickle.loads(f)

f.close()
print(data[‘age‘])
