Is that a question?<br>
<br>
If I were to guess, I'd say you should have asked "Why does this say<br>
that myclass does not havea run method?". Then the simple answer is:<br>
Because, well, it doesn't! Why do you expect it to have one?<br>

Because somebody made a mistake.<br>
I don't know if this is your code or something you found in a<br>
book or web page but whichever it's an error and Python won't<br>
run it.<br>
<br>
Also funct() is a waste of space since its never used...<br>

If you have a question it helps if you ask it rather than have us guess.<br>
<br>
In this case I'm guessing you got an error and you are wondering why?<br>
<br>
It's because you are calling the run() class method of myclass. And<br>
there is no such method.<br>
<br>
If that's not your question please post again with a bit more of a clue<br>
about what you want to know.<br>

Because you didn't give it any.<br>
Try<br>
main(funct())<br>
instead.<br>

Hi Amit,<br>
<br>
I've been using Django Rest Framework for developing a database-driven<br>
API. If you choose to follow their tutorial, you may accomplish your<br>
goal quite quickly while learning a lot about web APIs and quite good<br>
engineering at the same time. Tastypie is a similar option.<br>
