python之json&pickle

用于序列化的两个模块：

json：用于字符串和python数类型间进行转换

oickle：用于python特有的类型和python的数据类型间进行转换

json、pickle模块提供四个功能：dumps、dump、loads、load

使用json&pickle将转化成字符串写入文件

import json
import pickle

def sayhi(name):
    print("hello,", name)

info = {
    "name":"guoxf",
    "age":"18",
    "sex":"nan",
    "func":sayhi
}

info1 = {
    "name":"guoxf",
    "age":"18",
    "sex":"nan",
    # "func":sayhi
}

f = open("a.txt", "wb")
# json.dump(info1)    # 两者完全相等 json.dumps(info1)
pickle.dump(info, f)    # 两者完全相等 f.write(pickle.dumps(info))
f.close()

使用json&pickle将文件中的字符串转化成字典读取

import json
import pickle

def sayhi(name):
    print("hello,", name)

f = open("a.txt", "rb")
# data = json.loads(f.read())
# data = pickle.loads(f.read())
data = pickle.load(f)
print(data)

f.close()

print(data["func"]("gxf"))
