Json模块学习

JSON 模块

用法，与pickle一样。

import json


d = {
    "name":"chen",
    "role":"police",
    "blood": 76,
    "weapon":"ak47"
}

alive_palyers = ['alex','jack','rain']


print(json.dumps(d))

print(type(json.dumps(d)))


f = open("game.json",'w')
json.dump(d,f)
#json.dump(alive_palyers,f)   #多次dump后，load时会报错

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

{"name": "chen", "role": "police", "blood": 76, "weapon": "ak47"}
<class 'str'>

import json

f = open("game.json","r")
d = json.load(f)
print(d["role"])


----------------
police

pickle 与json 区别

pickle仅支持python，支持py中所有数据类型 class->object,function，datetime,

json支持所有语言，仅支持常规数据类型 str,int,dict,set,list,tuple
