将字典以字符串形式保存进文本:

1 #_*_coding:utf-8_*_
2 #__author__ = "csy"
3 info = {
4     'name':'csy',
5     'age':'31'
6 }
7 f = open("test.text","w")
8 f.write(str(info))
9 f.close()

当再次打开的时候,输出会是个字符串:

1 #_*_coding:utf-8_*_
2 #__author__ = "csy"
3 f = open("test.text","r")
4 data = f.read()
5 f.close()
6 print(data)

输出:

{'age': '31', 'name': 'csy'}

(1)可使用eval方式再次将字符串转换为字典:

1 #_*_coding:utf-8_*_
2 #__author__ = "csy"
3 f = open("test.text","r")
4 data = eval(f.read())
5 f.close()
6 print(data)
7 print(data['age'])
8 print(data['name'])

输出:

{'name': 'csy', 'age': '31'}
31
csy

(2)常用方法是使用Json再次将字符串转换为字典,首先保存时用json.dumps()方法:

 1 #_*_coding:utf-8_*_
 2 #__author__ = "csy"
 3 import json
 4 info = {
 5     'name':'csy',
 6     'age':'31',
 7     'job':'IT'
 8 }
 9 f = open("test.text","w")
10 f.write(json.dumps(info))
11 f.close()

反序列化:

1 #_*_coding:utf-8_*_
2 #__author__ = "csy"
3 import json
4 f = open("test.text","r")
5 data = json.loads(f.read())
6 f.close()
7 print(data)
8 print(data['age'])
9 print(data['name'],data['job'])

输出:

{'job': 'IT', 'name': 'csy', 'age': '31'}
31
csy IT
