字典与文本文档的转换

1.将字典写入文本文档

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()

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.文本文档到字典

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

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