---------- Let's go to views.py 

def home(request):
    rooms = Room.objects.all()
    context = {'rooms': rooms}
    return render(request, 'main/home.html', context)

def room(request, pk):
    room = Room.objects.get(id=pk)
    context = {'room': room}

    return render(request, 'main/room.html', context)
 

def createRoom(request):
    form = RoomForm()
    if request.method == 'POST':
        form = RoomForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('home')

    context = {'form': form}
    return render(request, 'main/room_form.html', context)


def updateRoom(request, pk):
    room = Room.objects.get(id=pk)
    form = RoomForm(instance=room)

    if request. method == 'POST':
        form = RoomForm(request.POST, instance=room)
        if form.is_valid():
            form.save()
            return redirect('home')

    context = {'form: form'}
    return render(request, 'main/room_form.html', context)

I see 
context = {'form': form}

and revised
    context = {"form": form}
    return render(request, 'main/room_form.html', context)



Mostly, This kind of errors is because of colon.

and Run again


 Fixed !

This Chapter, we're going to make basic dictionary.  mondict = {     "1" : "Janunary" ,     "2" : "February" ,     "3" : "March" ,     "4" : "April" } whenever you make dictionary in python, you're going to use open and close curly brackets "{ }" Let's run  print ( mondict [ "2" ]) you get "February"  you can also use "get" function print ( mondict . get ( "2" )) you can specify default value that I wanna use if the key is not found by using get function. so when you run this print ( mondict . get ( "6" )) 6 is not on the list, you're going to get "none"  you can also pass the default value to print out  print ( mondict . get ( "6" , "invalid value" )) and you're going to get "invalid value"

1. Push Elements Left or Right with the float Property The next positioning tool does not actually use position, but sets the float property of an element. Floating elements are removed from the normal flow of a document and pushed to either the left or right of their containing parent element. It's commonly used with the width property to specify how much horizontal space the floated element requires. The given markup would work well as a two-column layout, with the section and aside elements next to each other.  Let me   Give the #left item a float of left and the #right item a float of right. 2. Change the Position of Overlapping Elements with the z-index Property When elements are positioned to overlap (i.e. using position: absolute | relative | fixed | sticky), the element coming later in the HTML markup will, by default, appear on the top of the other elements. However, the z-index property can specify the order of how elements are stacked on top of one another. It ...
