一、使用json转换方法
1、字典写入txt

import json

dic = { \'andy\':{ \'age\': 23, \'city\': \'beijing\', \'skill\': \'python\' }, 
        \'william\': { \'age\': 25, \'city\': \'shanghai\', \'skill\': \'js\' } 
        }
js = json.dumps(dic)
file = open(\'test.txt\', \'w\')
file.write(js)
file.close()

2、读取txt中的字典

import json

file = open(\'test.txt\', \'r\') 
js = file.read()
dic = json.loads(js)   
print(dic) 
file.close()

二、使用str转换方法
1、字典写入txt

dic = { \'andy\':{ \'age\': 23, \'city\': \'beijing\', \'skill\': \'python\' }, 
        \'william\': { \'age\': 25, \'city\': \'shanghai\', \'skill\': \'js\' } 
        } 
fw = open("test.txt",\'w+\') 
fw.write(str(dic)) #把字典转化为str 
fw.close()

2、读取txt中字典

fr = open("test.txt",\'r+\')
dic = eval(fr.read())   #读取的str转换为字典
print(dic)
fr.close()
