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...
Writing JSON to a file To write JSON to a file in Python, we can use json.dump() method. Example 4: Writing JSON to a file import json person_dict = {"name": "Bob", "languages": ["English", "French"], "married": True, "age": 32 } with open('person.txt', 'w') as jso...
indent=4)# You could also write:pretty_response=json.dumps(response.json(),indent=4)print(pretty_response)# Returns:# {# "activity": "Have a football scrimmage with some friends",# "type": "social",# "participants": 8,# "price": 0,# ...
ret= json.dumps({'国籍':'美国'},ensure_ascii=False) f.write(ret+'\n') f.close() 其他参数说明 Serialize obj to a JSON formatted str.(字符串表示的json对象) Skipkeys:默认值是False,如果dict的keys内的数据不是python的基本类型(str,unicode,int,long,float,bool,None),设置为False时,就会报Type...
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 ...
