Python Results in Django HTML

I'm sorry for the super basic question but I am having the hardest time placing Python variables in my HTML file using Django.

#views.py ??  

def my_fucntion(temp):
    F = temp*(9.0/5)+32
    print F
                
weather = my_function(20)

How do I add this to my HTML file via Django?

<!-- results.html -->
<p>The temp is {{ weather }} Fahrenheit today.</p>

I am following the Django app tutorial but I cannot find where they explain this in detail. Do I need to put all my functions in views.py?

I've also tried rendering the result with no luck:

#views.py
def my_function(temp):
            F = temp*(9.0/5)+32
            print F
        
weather = my_function(20)

def weather(request):
    return render(request, "results.html", {"weather": weather})

I get an error for saying 'my_function' is not defined.

Again, I am very new at this so a simple step-by-step or how-to would be mega helpful. I've been searching the net for a few days and I'm pulling my hair out. I read the Django docs but get lost pretty quickly.

This seems like a very powerful tool and I just want to know how to get some of my Python scripts to display in HTML.

Thanks!!

EDIT:

Thanks for the info but this still isn't working for me. The tag is coming up blank when I pull the HTML up. Here is my code:

convert_temp.py

def my_function(temp):
    F = temp*(9.0/5)+32
    return F

views.py

...
import convert_temp
...
def weather(request):
    temp = convert_temp.my_function(20)
    return render(request, "polls/results.html", {"weather": temp})

results.html

...
<p>The temp is {{ weather }} Fahrenheit today.</p>

The result when I load up the page is "The temp is Fahrenheit today." Thanks again!!

weather = my_function(20) should be in your weather function and shouldn't be named weather if that's what you are using as a function name, also my_function should return instead of print:

def my_function(temp):
    F = temp*(9.0/5)+32
    return F

def weather(request):
    temp = my_function(20)
    return render(request, "detail.html", {"weather": temp})
