python 如何将字典写为json文件

python 如何将字典写为json文件

python 将字典写为json文件

字典结构如下

res = {
    "data":[]
}
temp = {
        "name":name,
        "cls":cls
}
res["data"].append(temp)

写为json

具体代码如下:

json_data = json.dumps(res)
with open("E:/res.json", "a") as f_six:
    f_six.write(json_data)

即可完成需求~~

Python txt文件读取写入字典(json、eval)

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() 

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()
