Doubt for Optional Labs

Hello Sir/Madam, I want to ask that while going through the optional labs, we are guided to run the code and observe the output. But, we are not able to code for self-practice. Kindly, guide us on a fruitful route for self-practicing on the codes.

One way of practicing that code that I have also heard from somewhere is just going about it and writing it on a private notebook of your own or better to come up with the code without looking at the solution all the time.

In addition to Gent’s answer, you can download and play with graded and ungraded assignments (after submitting your graded assignment) on your local computer. Here is the guide on how to download all the files of the assignment.
