Python 我在一个字典中有两个字典，无法确定如何访问特定值

我试着看其他的例子，但没有一个对我有帮助， 我的问题是常量或视图中的某个地方，我似乎无法从CONSTANTS.PY的登录页中获取header的值。请帮助我找出我在VIEWS.PY中调用的是如何错误的

常数.PY

videos = {'landing_page': {
    'header': 'What\'s it like to take a class at ?',
    'subheader': ' \"There are students who keep in touch for years after they\'ve taken a language class here.\" Learn more about the   experience and what it means to learn a language with us in the video below. You\'re not just taking a class; you\'re getting an immersive experience and joining a growing community',
    'url': 'https://www.youtube.com/'},
      'private_lesson': {
    'header': 'SEE WHAT A CLASS LOOKS LIKE AND MEET OUR TEACHERS',
    'subheader': ' \"There are students who keep in touch for years after they\'ve taken a language class here.\" Learn more about the  experience and what it means to learn a language with us in the video below. You\'re not just taking a class; you\'re getting an immersive experience and joining a growing community',
    'url': 'https://www.youtube.com/'}}

VIEWS.PY

@render_to('video-section.html')
def video_section(request):
context = {}
context['headerLP'] = c.videos['landing_page']['header']
return context

HTML文件

{% load staticfiles %}
<section class="video-section">
  <div class="padded-center-container">
    <h2>{{ headerLP }}</h2>
    <p>"There are students who keep in touch for years after they've 
taken a language class here." Learn more about the he video 
below. You're not just taking a class; you're getting an immersive 
experience and joining a growing community.</p>

  <div class="video-wrapper">

Python字典键不能是可变的，因此在

get（[{'subheader'}]）

中使用列表没有意义。也许你想要

c.videos['landing_page']['subheader']

或

c.videos['landing_page']。如果你需要处理密钥不存在的情况，那么获取（'subheader'）

。你是否尝试从

video_section（）

打印

c.videos

？要检查它是否像您给我们的示例。要清楚，是标题导致了问题，请忘记副标题。我尝试了

c.videos['landing\u page']['header']

和

c.videos['landing\u page'].get（'subheader'）

但我一直得到不好的模板变量你如何将视频字典从constants.py文件导入views.py？？什么是c？？如何从中访问c.视频。将常量导入为c
