#checkdatatypewithtype()method print(type(employee_string))#convert string to object json_object = json.loads(employee_string)#check newdatatypeprint(type(json_object)) 上面的代码就可以直接让 Python 把字符串转换为 JSON 的对象了。 当我们完成转换后,就可以对 JSON 的对象进行相关操作了。
使用json 进行转换存在一个潜在的问题。 由于json 语法规定 数组或对象之中的字符串必须使用双引号,不能使用单引号 (官网上有一段描述是 “A string is a sequence of zero or more Unicode characters, wrapped in double quotes, using backslash escapes” ),因此下面的转换是错误的: import json user_info ...
my_new_string_value = my_bytes_value.decode("utf-8") 但是当我尝试加载到JSON时: my_json = json.loads(my_new_string_value) 我收到此错误: json.decoder.JSONDecodeError: Expecting value: line 1 column 174 (char 173) 参考方案 您的bytes对象几乎是JSON,但是它使用单引号而不是双引号,并且它必...
您可以尝试以下操作: # helper method to convert equals sign to indentation for easier parsing def convertIndentation(inputString): indentCount = 0 indentVal = " " for position, eachLine in enumerate(inputString): if "=" not in eachLine: continue else: strSplit = eachLine.split("=", 1) ...
necessary but standard way to write code of particular function. '''formatted_obj = json.dumps(dic, indent=4, separators=(',',': '))print(formatted_obj) 输出: { "a" :4,"b":5} 为了更好地理解这一点,将缩进更改为40并观察输出 - ...

Testing the code To test the code, simply run it in a tool of your choice. I’ll be using IDLE, a Python IDE. You should get an output similar to figure 1. In the first print we can see that the dictionary was correctly converted to a compact JSON string, as expected. In the se...
