接下来, 笔者是要进行详细说明的, 在其中, 字典与JSON字符串之间相互转化这件事, 我们能够借助json模块来达成。1.字典转换为JSON字符串把字典凭借函数json.dumps(), 转变成JSON字符串。import json # 定义一个字典 my_dict {name: John, age: 30, city: New York} # 将字典转换为JSON字符串 json_string json.dumps(my_dict) print(json_string) # 输出{name: John, age: 30, city: New York}2.JSON字符串转换为字典把JSON字符串借助json.loads()函数, 转变成字典。import json # 定义一个JSON字符串 json_string {name: John, age: 30, city: New York} # 将JSON字符串转换为字典 my_dict json.loads(json_string) print(my_dict) # 输出{name: John, age: 30, city: New York}注意事项1.JSON字符串的格式必须是有效的JSON格式。·如果JSON字符串格式不正确将会引发json..异常。2.字典中的键和值必须是JSON兼容的类型。·JSON所支持的值, 仅限于字符串, 以及数字, 还有布尔值, 再加上列表, 以及字典另外还有None。要是字典之中存有别的类型, 像自定义类的实例或者函数之类的, 在进行转换的时候可是有可能引发异常的。3.注意处理转换可能引发的异常。在进行转换这个行为的时候呢, 务必要留意去处理那些有可能会出现的异常情形, 从而以此为准来确保那程序所具备的健壮性。4.可以使用参数美化JSON字符串。·json.dumps()函数中, 参数能够被设置为缩进空格数, 进而致使输出的JSON字符串较为容易就能够被人读懂。import json my_dict {name: John, age: 30, city: New York} # 设置缩进为4个空格 json_string json.dumps(my_dict, indent4) print(json_string) # 输出格式 # { # name: John, # age: 30, # city: New York # }关于把中字典跟JSON字符串进行相互转化的办法, 就是以上这些, 期望能够对你起到一定的帮助作用。WWw.M.nffqi.cN/Article/details/839915.shtmlWWw.M.nffqi.cN/Article/details/297531.shtmlWWw.M.nffqi.cN/Article/details/783273.shtmlWWw.M.nffqi.cN/Article/details/553061.shtmlWWw.M.nffqi.cN/Article/details/702288.shtmlWWw.M.nffqi.cN/Article/details/287248.shtmlWWw.M.nffqi.cN/Article/details/612776.shtmlWWw.M.nffqi.cN/Article/details/588783.shtmlWWw.M.nffqi.cN/Article/details/944406.shtmlWWw.M.nffqi.cN/Article/details/552017.shtmlWWw.M.nffqi.cN/Article/details/785936.shtmlWWw.M.nffqi.cN/Article/details/866942.shtmlWWw.M.nffqi.cN/Article/details/015717.shtmlWWw.M.nffqi.cN/Article/details/318971.shtmlWWw.M.nffqi.cN/Article/details/817533.shtmlWWw.M.nffqi.cN/Article/details/850091.shtmlWWw.M.nffqi.cN/Article/details/687029.shtmlWWw.M.nffqi.cN/Article/details/747915.shtmlWWw.M.nffqi.cN/Article/details/746647.shtmlWWw.M.nffqi.cN/Article/details/149089.shtmlWWw.M.nffqi.cN/Article/details/289541.shtmlWWw.M.nffqi.cN/Article/details/056553.shtmlWWw.M.nffqi.cN/Article/details/264586.shtmlWWw.M.nffqi.cN/Article/details/094314.shtmlWWw.M.nffqi.cN/Article/details/214723.shtmlWWw.M.nffqi.cN/Article/details/105543.shtmlWWw.M.nffqi.cN/Article/details/478061.shtmlWWw.M.nffqi.cN/Article/details/250274.shtmlWWw.M.nffqi.cN/Article/details/067529.shtmlWWw.M.nffqi.cN/Article/details/813395.shtmlWWw.M.nffqi.cN/Article/details/471028.shtmlWWw.M.nffqi.cN/Article/details/636150.shtmlWWw.M.nffqi.cN/Article/details/976805.shtmlWWw.M.nffqi.cN/Article/details/349942.shtmlWWw.M.nffqi.cN/Article/details/522207.shtmlWWw.M.nffqi.cN/Article/details/818946.shtmlWWw.M.nffqi.cN/Article/details/482377.shtmlWWw.M.nffqi.cN/Article/details/834998.shtmlWWw.M.nffqi.cN/Article/details/946334.shtmlWWw.M.nffqi.cN/Article/details/555848.shtmlWWw.M.nffqi.cN/Article/details/879558.shtmlWWw.M.nffqi.cN/Article/details/479051.shtmlWWw.M.nffqi.cN/Article/details/531313.shtmlWWw.M.nffqi.cN/Article/details/444234.shtmlWWw.M.nffqi.cN/Article/details/462362.shtmlWWw.M.nffqi.cN/Article/details/451182.shtmlWWw.M.nffqi.cN/Article/details/262661.shtmlWWw.M.nffqi.cN/Article/details/889710.shtmlWWw.M.nffqi.cN/Article/details/147122.shtmlWWw.M.nffqi.cN/Article/details/333061.shtmlWWw.M.nffqi.cN/Article/details/418644.shtmlWWw.M.nffqi.cN/Article/details/619470.shtmlWWw.M.nffqi.cN/Article/details/533535.shtmlWWw.M.nffqi.cN/Article/details/218096.shtmlWWw.M.nffqi.cN/Article/details/570361.shtmlWWw.M.nffqi.cN/Article/details/270681.shtmlWWw.M.nffqi.cN/Article/details/960880.shtmlWWw.M.nffqi.cN/Article/details/920135.shtmlWWw.M.nffqi.cN/Article/details/803842.shtmlWWw.M.nffqi.cN/Article/details/689582.shtmlWWw.M.nffqi.cN/Article/details/149076.shtmlWWw.M.nffqi.cN/Article/details/288539.shtmlWWw.M.nffqi.cN/Article/details/690963.shtmlWWw.M.nffqi.cN/Article/details/769037.shtmlWWw.M.nffqi.cN/Article/details/779944.shtmlWWw.M.nffqi.cN/Article/details/011260.shtmlWWw.M.nffqi.cN/Article/details/884770.shtmlWWw.M.nffqi.cN/Article/details/189608.shtmlWWw.M.nffqi.cN/Article/details/044799.shtmlWWw.M.nffqi.cN/Article/details/198488.shtmlWWw.M.nffqi.cN/Article/details/176535.shtmlWWw.M.nffqi.cN/Article/details/282791.shtmlWWw.M.nffqi.cN/Article/details/132205.shtmlWWw.M.nffqi.cN/Article/details/789170.shtmlWWw.M.nffqi.cN/Article/details/584152.shtmlWWw.M.nffqi.cN/Article/details/563387.shtmlWWw.M.nffqi.cN/Article/details/190754.shtmlWWw.M.nffqi.cN/Article/details/895696.shtmlWWw.M.nffqi.cN/Article/details/776245.shtmlWWw.M.nffqi.cN/Article/details/929496.shtmlWWw.M.nffqi.cN/Article/details/145122.shtmlWWw.M.nffqi.cN/Article/details/275354.shtmlWWw.M.nffqi.cN/Article/details/334541.shtmlWWw.M.nffqi.cN/Article/details/800943.shtmlWWw.M.nffqi.cN/Article/details/533365.shtmlWWw.M.nffqi.cN/Article/details/352650.shtmlWWw.M.nffqi.cN/Article/details/133276.shtmlWWw.M.nffqi.cN/Article/details/128245.shtmlWWw.M.nffqi.cN/Article/details/884272.shtmlWWw.M.nffqi.cN/Article/details/269213.shtmlWWw.M.nffqi.cN/Article/details/135435.shtmlWWw.M.nffqi.cN/Article/details/923017.shtmlWWw.M.nffqi.cN/Article/details/995627.shtmlWWw.M.nffqi.cN/Article/details/012335.shtmlWWw.M.nffqi.cN/Article/details/444749.shtmlWWw.M.nffqi.cN/Article/details/073469.shtmlWWw.M.nffqi.cN/Article/details/462209.shtmlWWw.M.nffqi.cN/Article/details/891289.shtmlWWw.M.nffqi.cN/Article/details/192628.shtmlWWw.M.nffqi.cN/Article/details/570888.shtmlWWw.M.nffqi.cN/Article/details/709050.shtmlWWw.M.nffqi.cN/Article/details/430678.shtmlWWw.M.nffqi.cN/Article/details/524037.shtmlWWw.M.nffqi.cN/Article/details/909838.shtmlWWw.M.nffqi.cN/Article/details/706169.shtmlWWw.M.nffqi.cN/Article/details/455542.shtmlWWw.M.nffqi.cN/Article/details/200516.shtmlWWw.M.nffqi.cN/Article/details/781145.shtmlWWw.M.nffqi.cN/Article/details/375950.shtmlWWw.M.nffqi.cN/Article/details/921701.shtmlWWw.M.nffqi.cN/Article/details/226943.shtmlWWw.M.nffqi.cN/Article/details/050527.shtmlWWw.M.nffqi.cN/Article/details/977560.shtmlWWw.M.nffqi.cN/Article/details/232669.shtmlWWw.M.nffqi.cN/Article/details/549644.shtmlWWw.M.nffqi.cN/Article/details/612892.s
