Add examples for List, Tuple, Dictionaries and Set

In this repo, There is no examples and any documentation for the basic data structures like list, tuples, dictionaries and set. We should need to add this.

Web Sraping directory renamed/changed to Web Scraping. Pull request #166

It would be better if we add some points which are important to understand the Object Oriented Programming.
I would like to add Functions by Passing the Parameter
and Abstract Class, Inheritance, Constructor(init) function, polymorphism.

###Please consider the following changes for the Lesson 4 README. Please let me know if I should submit a pull request.

OOP Implementation Using Python

TASK 1:

Refer to the web site for information about the Python turtle module. Study about Class implementation from given repository resources and write a python script for making an animation of multiple squares deviating at an angle to form a circle.

Assistance:

• The Python Standard Library has a module called turtle.
• The turtle module has a class called Turtle.
• Calling turtle.Turtle() instantiates the class.
• Refer to the web site for turtle documentation.
• Check on Resources to get the solution.

TASK 2:

Using the Twilio python module (which is not a part of the Standard Python Library), write a python script that can send a message to a phone number. Study about Twilio and python usage from the Internet.

(Messages from a small piece of code?? Interesting!)

Assistance:

• Study the 'twilio' module.
• A Twilio account is needed to use the API.
• Be careful about Auth Tokens.
• Refer to the web site for complete documentation of the twilio module.
• Check on Resources to get the solution.

About Used Modules:

• https://www.twilio.com/docs/libraries/python
• https://docs.python.org/2/library/turtle.html

Describe the solution you'd like

Describe alternatives you've considered

Additional context
Added some points which I felt were necessary in the Lesson 1 of your course.

A small example of running codes in python relating to Object-Oriented concepts in python can be added in a new folder called "Examples"

https://github.com/Arg85/Learning-Object-Oriented-Python

After going through the resources, the practice questions will help people gain a better understanding of the concepts.

this is a wonderful repo. the English only needs a little bit of help in some of the markdown files.

Describe the solution you'd like
I would like for people who are fluent or native English speakers to comb through the markdown files and improve the wording, context, and sentence structure.

The README.md is a bit low on what the course is all about. I guess telling a bit about object-oriented programming in the start itself will give newbies a heads up on what they are diving into.

I think it'd be good to add information about scoping rules in regards to functions. Global versus local and how that relates to passing values into functions, whether or not values need to be returned from a functions, etc.

Describe the solution you'd like
It'd be examples broken down into parts. One part using locals, another with globals, then maybe another with both locals & globals.

In lesson 2, perhaps it would be useful to explain why functions are useful in python, to new users.

So, what the above mentioned file does not include, is an explanation of how .capitalize() works. It does two things: first, it will capitalize the first character, as long as it is a letter. If you try to call the method on something that has a blank space or a number or any non-letter character as the first character, it will not work. Second, it will convert all other letters to lowercase.

I am adding inheritance in detail to the oop concepts

Describe the solution you'd like
code showing single, multiple inheritances and multi-level inheritance

Your Web Scrapping Folder Lesson is not written in a much efficient way. I can write from the start in a better way. I want to add some advanced topics like crawling the Goodreads website and making a data frame for the author, quotes, and tags, etc.

if that's not possible, could I just add some advanced topic to it?

Creating a function to display images

When you navigate the lessons, the user clicks on the directory (i.e., Course Introduction), and is shown the contents of the directory. The user then must know to click on the markdown file to see the information.

Describe the solution you'd like
A simple change that would make the repo easier to use is to rename the markdown files in each lesson subdirectory to README.md. If you do that, when you click on the directory, the markdown will auomatically show, without having to select it.

Describe alternatives you've considered
It is fine as it is - most users will know what to do, but this change is simple and may make the repo easier to use.

Additional context
Just comment if you would like for me to make this change and I'll raise a PR.

Describe the solution you'd like
Want to add a markdown file for string manipulation and update the Introduction.md file

What i am adding ?
As introduction for OOPS there are 4 pillars of OOPS but in the section only 1 of them is mentioned so I want to add the rest 3 with short introduction of them.

So I was going through this repository and I found (to what I went through, and I didn't go thoroughly) that there isn't anything regarding Abstract Base Classes, even though they are quite an important aspect of Object-Oriented Programming.
In lieu of this, I suggest that both the code and an explanation should be added in here.
I myself have come up with the solution and I'll be making a pull request soon. However, others are encouraged to add something of the sort, and it might turn out better than what I come up with. Peace ✌🏻

I thought Lesson 1 could contain a Python file that introduces the user to

• how variable types work
• some basic string operations
• how to use loops and data structures

(read the contribution.md so i hope i'm doing this right, sorry newbie to contributing)

Hi, I would like to suggest some additional content teaching polymorphism in Lesson 3 of the project!

Just an FYI that there is a missing letter inside the prank folder

** just like this**

response = requests.get(url)

Issue
In the Function.py and functions.md file, there's alreasy a primer on creating and calling a function. But besides this, maybe a short refresher on recursion might help too

Proposed Pull Request
Added a short primer on recursion using the classic example of calculating factorials. Deliberately didn't include hadnling edge cases like floating point numbers and mentioned it as a sort of 'challenge' in the functions.md file
