這篇文章主要介紹了Python json轉(zhuǎn)字典字符代碼實例解析,文中通過示例代碼介紹的非常詳細，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價值,需要的朋友可以參考下

josn基本操作

1.導(dǎo)入import json

2.字典轉(zhuǎn)json：json.dumps(dict,ensure_ascii=False)，加,ensure_ascii=False轉(zhuǎn)換之后無中文亂碼

3.json轉(zhuǎn)字典：json.loads(str)

4.json轉(zhuǎn)字典：requests.get().josn()

5.返回字符串： requests.get().text

舉例源碼

#!/usr/bin/python3
# encoding:utf-8
import json
import requests

class jsonC():
  def __init__(self):
    self.url = 'http://wthrcdn.etouch.cn/weather_mini?city=北京'
    self.geturl = requests.get(self.url)
  
  #字典轉(zhuǎn)json,因為python沒json類型所以str表示
  def dict_json(self):
    d = {"name":"張三","age":18}
    j = json.dumps(d,ensure_ascii=False)
    print('dict_json函數(shù)：類型：',type(d),'轉(zhuǎn)類型',type(j),'\n',j)
  
  #json轉(zhuǎn)字典  
  def json_dict(self):
    s = '{"name":"張三","age":18}'
    d = json.loads(s)
    print('json_dict函數(shù)：類型：',type(s),'轉(zhuǎn)類型',type(d))
    
  #接口調(diào)用直接返回 字典（dict） 
  def get_json(self):
    d = self.geturl.json()
    print('get_json函數(shù)類型：',type(d))
  
  #接口調(diào)用直接返回字符串  
  def get_str(self):
    s = self.geturl.text
    print('get_str函數(shù)返回類型：',type(s))
    
if __name__=="__main__":
  js = jsonC()
  js.dict_json()
  js.json_dict()
  js.get_json()
  js.get_str()

運行結(jié)果

dict_json函數(shù)：類型： <class 'dict'> 轉(zhuǎn)類型 <class 'str'>
{"name": "張三", "age": 18}
json_dict函數(shù)：類型： <class 'str'> 轉(zhuǎn)類型 <class 'dict'>
get_json函數(shù)類型： <class 'dict'>
get_str函數(shù)返回類型： <class 'str'>

調(diào)用get例子

http://wthrcdn.etouch.cn/weather_mini?city=北京

返回json值：

{"data":
	{"yesterday":
		{"date":"28日星期六","high":"高溫 30℃","fx":"西南風(fēng)","low":"低溫 17℃","fl":"<![CDATA[<3級]]>","type":"晴"},
		"city":"北京","forecast":
		[
			{"date":"29日星期天","high":"高溫 29℃","fengli":"<![CDATA[<3級]]>","low":"低溫 18℃","fengxiang":"南風(fēng)","type":"晴"},
			{"date":"30日星期一","high":"高溫 28℃","fengli":"<![CDATA[<3級]]>","low":"低溫 19℃","fengxiang":"南風(fēng)","type":"晴"},
			{"date":"1日星期二","high":"高溫 29℃","fengli":"<![CDATA[<3級]]>","low":"低溫 20℃","fengxiang":"南風(fēng)","type":"多云"},
			{"date":"2日星期三","high":"高溫 29℃","fengli":"<![CDATA[<3級]]>","low":"低溫 17℃","fengxiang":"南風(fēng)","type":"晴"},
			{"date":"3日星期四","high":"高溫 30℃","fengli":"<![CDATA[<3級]]>","low":"低溫 12℃","fengxiang":"東南風(fēng)","type":"多云"}
		],"ganmao":"各項氣象條件適宜，無明顯降溫過程，發(fā)生感冒機率較低。","wendu":"29"
	},"status":1000,"desc":"OK"
}
