python之json数据存储
# 数据存储:json.dump()和json.load() # date:2017-07-17 import json file_name = 'D:/json_file.txt' nums = [3, 4, 5, 7, 1, 9] # nums = {"name": "Mike", "age": 12} with open(file_name, 'w') as file_obj: '''写入json文件''' json.dump(nums, file_obj) print("写入json文件:", nums) with open(file_name) as file_obj: '''读取json文件''' numbers = json.load(file_obj) # 返回列表数据,也支持字典 print("读取json文件:", numbers)
运行结果:
写入json文件: [3, 4, 5, 7, 1, 9] 读取json文件: [3, 4, 5, 7, 1, 9]
