Lets say i have a dictionary or a simple object, i dont know its structure and i

Answer 1

I needed something similar, but also wanted to pretty print lists, and lists inside the dict. Here's what I came up:

def format(self, obj, indent = 1):
    if isinstance(obj, list):
        htmls = []
        for k in obj:
            htmls.append(self.format(k,indent+1))

        return '[<div style="margin-left: %dem">%s</div>]' % (indent, ',<br>'.join(htmls))

    if isinstance(obj, dict):
        htmls = []
        for k,v in obj.iteritems():
            htmls.append("<span style='font-style: italic; color: #888'>%s</span>: %s" % (k,self.format(v,indent+1)))

        return '{<div style="margin-left: %dem">%s</div>}' % (indent, ',<br>'.join(htmls))

    return str(obj)

Then, if you're using webapp on appengine, you can just do the following:

self.response.out.write(self.format(obj))

This is an example of the output:

Here's my simple solution, It can handle any level of nested dictionary.

import json
temp_text = {'decision': {'date_time': None, 'decision_type': None},
             'not_received': {'date_time': '2019-04-15T19:18:43.825766'},
             'received': {'date_time': None},
             'rfi': {'date_time': None},
             'under_review': {'date_time': None}}
dict_text_for_html = json.dumps(
    temp_text, indent=4
).replace(' ', '&nbsp').replace(',\n', ',<br>').replace('\n', '<br>')

imagine we have this :{name: "a", children:[{name: "b", children: [] },{..},{..}]

def ConvertDictToUlLi():
    jsonResult = GetSomeRecursiveDict()

    def CreateHtml(DictItem, output):
        output = "<li>"+DictItem["name"] if jsonResult.has_key("name") else " "
        if len(DictItem["children"]) > 0:
           output = output + "<ul>"
           for item in DictItem["children"]:
              output = output + "  "+CreateHtml(item, output)+"  "
           output = output + "</ul>"
      return output+"</li>"
    result = "<ul class='tree'>"+CreateHtml(jsonResult, "")+"</ul>"

return result
