print(pretty_json_str) 1. 运行以上代码,就能够将格式化的JSON字符串输出到控制台。 示例代码 下面是完整的示例代码: importjson# 定义一个字典data={"name":"Alice","age":20,"city":"New York"}# 将字典转换为JSON字符串json_str=json.dumps(data)# 将JSON字符串转换为Python对象python_obj=json.loads...
Given its prevalence and impact on programming, at some point in your development you'll likely want to learn how to read JSON from a file or write JSON to a file. Both of these tasks are pretty easy to accomplish with Python, as you'll see in the next few sections. Writing JSON to...
First, we usejson.loads()to create the JSON object from the JSON string. Thejson.dumps()method takes the JSON object and returns a JSON formatted string. Theindentparameter defines the indent level for the formatted string. 2. Python Pretty Print JSON File ...
