Q: What is Mutability?
A: Mutability means the tendency to change. So, lists are mutable while tuples and strings are immutable.
Once we declare a data structure and if we are unable to edit the same(tuples, strings, etc), then it is called immutable data structure, while it is the opposite for mutable data structure(lists, etc).

Nobody will tell us these small details like U are doing. Not our college/school teachers, maybe not even our private tutors or most of the Youtubers either. I cannot express how much I appreciate your work & only wish had I found this channel earlier, would've spared me a lot of troubles. But fortunately it's never too late & now I'm here & enjoying this amazing work of your. Thanks a lot, Sir😊

For those..who are unable to find appdata folder, follow these steps. 1) control panel 2) appearance and personalization 3) file explorer 4) view and then show hidden files...!

To all those people who are
struggling to add python into path in environment variables,
just follow this:
1)uninstall python
2)reinstall python
3)on the installation screen on the bottom you'll see an option "add to path"
4)just mark it and you'll be fine
i think restart might be required do it.

[monagulapa]

You are an amazing person. Not all can educate others. That's a gift. And you have it. Thank you for sharing your gift.

Just managed to do it. Hope it helps, this is what I did
1) Searched for Environmental Variables in the search bar
2) Look at the bottom right of the box that appears, press ok on the Enviromental Variable box
3) Environmental and System variable box comes up, we want the System box.
4) Go to Path in the System box, press Edit. This is where you need to paste your Python path and script path.

Hi Navin, Thank you for your incomparable knowledge being shared. I am working on Spark using Scala. I am curious to know if i will be able to code in python for Spark by the end of your sessions. Thanks again
