如何解决如何用Python中的嵌套字典创建Bootstrap手风琴？
d = {1: {4: {6: {},7: {},8: {}},5: {}},2: {},3: {}}
可以可视化为：
1
4
6
7
8
5
2
3
我的目标是创建一个类似于此链接给出的引导手风琴：https://codepen.io/glebkema/pen/QQOZRe?editors=1000
这里有一个屏幕截图：
为了实现我的目标，我认为可以在可以使用flask呈现的python脚本中生成HTML代码。我想出的代码是这样的：
def pretty(d,indent=0,indent_before=0):
html_code = ''
for key,value in d.items():
if indent > indent_before:
html_code += """
<div id="collapse-1-1" class="collapse" data-parent="#accordion-1" aria-labelledby="heading-1-1">
<div class="card-body">
<div id="accordion-1-1">
"""
elif indent == indent_before:
html_code += """
</div>
"""
else:
html_code += """
</div>
"""*indent
html_code +="""
<div class="card">
<div class="card-header" id="heading-{}">
<h5 class="mb-0">
<a role="button" data-toggle="collapse" href="#collapse-{}" aria-expanded="false" aria-controls="collapse-{}">
{}
</a>
</h5>
</div>
""".format(key,key,indent)
#print('\t' * (indent) + str(key) + '({})({})\n'.format(indent,indent_before))
if isinstance(value,dict):
html_code += pretty(value,indent+1,indent)
else:
print('\t' * (indent+1) + str(value))
return html_code
msg = pretty(result)
print(msg)
基本上，这是一个递归函数，它遍历所有字典项。但是这段代码有3个测量错误，我不知道如何解决：
我得到的输出如下：
<div class="card">
<div class="card-header" id="heading-1">
<h5 class="mb-0">
<a role="button" data-toggle="collapse" href="#collapse-1" aria-expanded="false" aria-controls="collapse-1">

</div>
<div id="collapse-1-1" class="collapse" data-parent="#accordion-1" aria-labelledby="heading-1-1">

您能提出一种巧妙而优雅的方法来从字典开始生成手风琴吗？只要获得我可以渲染的HTML代码，就可以根据需要修改代码。我还考虑过使用Jinja2，但对此一无所知。预先感谢。
解决方法
我能够解决我的真正问题。这是代码：
def pretty(d,indent=0,indent_previous_layer=-1,counter=0):
html_code = ''
indent_privious_item = indent_previous_layer
for key,value in d.items():
if indent > indent_privious_item and counter!=0:
html_code += """
<div id="collapse-{}" class="collapse" data-parent="#accordion-{}" aria-labelledby="heading-{}">
<div class="card-body">
<div id="accordion-{}">
""".format(counter,indent-1,counter,indent)
elif indent == indent_privious_item:
html_code += """
</div>
"""
if indent==0:
html_code += """
<!--End of Card-->
"""
elif indent < indent_privious_item:
if indent==0:
html_code += """
</div>
"""
html_code += """
</div>
</div>
</div>
</div>
"""*(indent_privious_item-indent)
html_code += """
<!--End of Card-->
"""
else:
html_code += """
</div>
"""
html_code += """
</div>
</div>
</div>
</div>
"""*(indent_privious_item-indent)
html_code +="""
<div class="card">
<div class="card-header" id="heading-{}">
<h5 class="mb-0">
<a role="button" data-toggle="collapse" href="#collapse-{}" aria-expanded="true" aria-controls="collapse-{}">
Depth Level {}
</a>
</h5>
</div>
<div class="card-body pb-0">
<!--h5 class="card-title"></h5-->
<p class="card-text">{}</p>
<ul class="list-group">""".format(counter+1,counter+1,indent,"Some text")
html_code += """
</ul>
</div>
"""
if isinstance(value,dict):
code,indent_privious_item,counter = pretty(value,indent+1,counter+1)
html_code += code
else:
print('\t' * (indent+1) + str(value))
return html_code,counter
