In this lecture we will learn:
- Variables in Python
- Memory area of variables in Python
- How to get the address of a variable?
- Garbage collection
- Data types in Python

#1
- Every variable has its address.
- In Python, the id() function is used to get the address of a variable.
- We can also assign the value of one variable to any other variable.
- In python, whenever you create multiple variables and if they have the same data then they will point towards the same box or same memory area.
- Everything is an object in Python.
- Variables are also known as tags as we tag the value with a variable.
- If the same variable store multiple values, then that variable will point towards the new memory area where the new value is get stored.

#2
- If there is any data present in the memory that is not referenced by any variable, then that will be removed from the memory by the Garbage collector.

#3
- The value of variables can be changed but the value of the constant remains the same.
- In python, we represent constants through capital letters.
- type() function is used to get the data type of value of a variable.
- Besides in-built data types, we can also create our own types.

Good Part is...He is intelligently explaining the series without confusing the people who already learnt other languages

[yatinkathuria]

Set is the collection of non repeated elements while list is the collection of any type of element and any number of times.
Set is define by { }
List is define by [ ]

[betecieai]

Set is collection of unique elements, like in list if you repeat something i.e some number like 12 then it is repeated again, but in sets if you write 12 number 2 times then it will display only once, so this is 1st one. 2nd one is set is working on concept of hash, where list not working on concept of hash! 3rd one is in sets index number is not working, because sets can't maintain sequence, but list maintain sequence, eo index number is working in list! So these are some of difference between set and list!
Thank you!

If b=a why does the value of b not update when you change a

Shot for the course, being managing Production, Test and Development teams for 15 years, decided this is the year I start learning how to code, so far so good! Last time I touched any form of code was Turbo Pascal in 1990 ! @ Lesson 7 and easy enough to understand!

i love the way he gets every little detail and explains it perfectly without any confussion i ussually dont like teachers but this one i love

[Ajaysaini]

1. Set is collection of objects which is shows in curly brackets{} wher list shows in square brackets[]
2. Set is collection of objects where repeation of objects is not allowed but in list repeation of objects is allowed.
3. In set indexing and slicing operation not applied bcz in set sequence is not defined but list performs indexing and slicing.
