**Python Django - The Practical Guide - Lecture025-Returning HTML-opendir.cloud**

In this lecture, we will learn how to return HTML from a Django view. This is a very important skill, as it allows us to create dynamic and interactive web pages.

To return HTML from a Django view, we can use the `render()` function. This function takes two arguments: the template that we want to render and the context that we want to pass to the template.

The template is a file that contains HTML code and placeholders for variables. The context is a dictionary of variables that we want to pass to the template.

To render a template, we can use the following code:




```

python
from django.shortcuts import render

def my_view(request):
context = {}
return render(request, 'my_template.html', context)


```




This code will render the template `my_template.html` and pass the empty context to the template.

If we want to pass variables to the template, we can add them to the context dictionary. For example, the following code will render the template `my_template.html` and pass the variable `name` to the template:




```

python
from django.shortcuts import render

def my_view(request):
context = {'name': 'Alice'}
return render(request, 'my_template.html', context)


```



The template can then access the variable `name` using the following code:




```

html
{ h1 }Hello, {{ name }}!{ /h1 }


```



This will render the following HTML:



```

html
{ h1 }Hello, Alice! { /h1 }


```



We can also use the `render()` function to return HTML from a Django class-based view. To do this, we can override the `render()` method.

The following code shows a class-based view that returns the template `my_template.html` and passes the variable `name` to the template:




```

python
from django.views.generic import TemplateView

class MyView(TemplateView):
template_name = 'my_template.html'

def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['name'] = 'Alice'
return context


```



This view can be used as follows:



```

python
url(r'^my_view/$', MyView.as_view(), name='my_view'),


```



When we visit the URL `/my_view/`, the class-based view will be rendered and the template `my_template.html` will be displayed.
