Pretty JSON Formatting in IPython Notebook
提问by Kyle Brandt
Is there an existing way to get json.dumps()output to appear as "pretty" formatted JSON inside ipython notebook?
是否有现有的方法可以让json.dumps()输出在 ipython notebook 中显示为“漂亮”格式的 JSON？
采纳答案by filmor
json.dumpshas an indentargument, printing the result should be enough:
json.dumps有一个indent论点，打印结果应该就足够了：
print(json.dumps(obj, indent=2))

I found this page looking for a way to eliminate the literal \ns in the output. We're doing a coding interview using Jupyter and I wanted a way to display the result of a function real perty like. My version of Jupyter (4.1.0) doesn't render them as actual line breaks. The solution I produced is (I sort of hope this is notthe best way to do it but...)
我发现这个页面正在寻找一种方法来消除\n输出中的文字s。我们正在使用 Jupyter 进行编码面试，我想要一种方法来显示像. 我的 Jupyter (4.1.0) 版本不会将它们呈现为实际的换行符。我产生的解决方案是（我有点希望这不是最好的方法，但是......）
import json
output = json.dumps(obj, indent=2)
line_list = output.split("\n") # Sort of line replacing "\n" with a new line
# Now that our obj is a list of strings leverage print's automatic newline
for line in line_list:
print line
I hope this helps someone!

import uuid
from IPython.display import display_javascript, display_html, display
import json
class RenderJSON(object):
def __init__(self, json_data):
if isinstance(json_data, dict):
self.json_str = json.dumps(json_data)
else:
self.json_str = json_data
self.uuid = str(uuid.uuid4())
def _ipython_display_(self):
display_html('<div id="{}" style="height: 600px; width:100%;"></div>'.format(self.uuid), raw=True)
display_javascript("""
require(["https://rawgit.com/caldwell/renderjson/master/renderjson.js"], function() {
document.getElementById('%s').appendChild(renderjson(%s))

""" % (self.uuid, self.json_str), raw=True)
To ouput your data in collapsible format:
以可折叠格式输出数据：
RenderJSON(your_json)

This might be slightly different than what OP was asking for, but you can do use IPython.display.JSONto interactively view a JSON/dictobject.
这可能与 OP 要求的略有不同，但您可以使用IPython.display.JSON交互式查看 JSON/dict对象。
from IPython.display import JSON
JSON({'a': [1, 2, 3, 4,], 'b': {'inner1': 'helloworld', 'inner2': 'foobar'}})
Edit: This works in Hydrogen and JupyterLab, but not in Jupyter Notebook or in IPython terminal.
编辑：这适用于 Hydrogen 和 JupyterLab，但不适用于 Jupyter Notebook 或 IPython 终端。

I am just adding the expanded variable to @Kyle Barron answer:
我只是将扩展变量添加到@Kyle Barron 答案中：
from IPython.display import JSON
JSON(json_object, expanded=True)
