Python txt文件读取写入字典的方法(json、eval)

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()
