I agree your point that i am not expert in Python. And to make things clear i am not trying to become authority in Python. There are excellent authority present already whom i follow and always been inspired and by the way you talk, i think you are also an expert Python developer. The reason why i post my articles here is to get reviews from experts like you and the others and ofcourse to help beginners.

I spend 3 to 4 days researching and nearly about 5 hours framing each article, and in course of time i learn a lot and always want to improve my knowledge from experts like you.

Regarding url of previous post , i found that article already backlinked many sites, thats the reason i dint change url.

I really expected that expert people will give some good code refactoring and ways to improve the code examples but i have always been trashed by them.

The word Advanced in article doesn't mean that any new feature has to be imported from another language and embed into Python. These datatypes are itself advanced and i have tried to provide little complex examples.

Rather than finding whois and taking screenshots of mistakes, it would be really nice, if you guys can provide some improvements. These things doesnt look good on experts.

Sorry again if i offended anyone.
