Python Sample Code contains all the example explained while teaching Python. Sample Code is organized as per the order of the episodes. Each sample code includes complete source code the example from basic print statement to Complex Numpy examples.

But again it’s a request view the sample code only if you have tried 10 times while watching Pytyhon Online Session.

If you enrolled for the course you can refer the episode number or name of the session to get the source code. If you have not enrolled for the Python Online Curse Please Click and enrol today.

**For enrolled students, we also provide online support along with additional Practice Series.**

If you think this sample code is not enough please refer to our practice series available 100% free on YouTube. Here is the link of Python Practice Series with many new examples. We will add new examples of Python Practice each and every Saturday.

## Does Sample Python Code Include all the exercise ?

Nope. The answer is no. It includes the example only explain in the source code. More example of the practice is available here (Python Exercise List).

## Episode 3 to Episode 5 Python Sample Code

All the sample Code from Episode 3 to 5. Since First and Second episode of Python don’t have any source code explanation we are skipping that.

### Episode 3 – Sample Code
