Things to know

What is this course about?

Python is a high-level, interpreted, general-purpose programming language that powers both web and desktop platforms. It supports multiple paradigms of coding including object-oriented, procedular, functional and imperative.

It's an extremely popular programming language on the charts, capable of being used in very sophisticated fields such as data science, machine learning, AI, and web development.

It's extremely easy to use and has a very gentle learning curve. If you start today, you'll be able to develop some rigorous programs in lesser than a week!

Python favours code readability via the offside rule — where a block of code is represented by an increased level of indentation as opposed to delimiters such as {} (curly braces) used in languages such as JavaScript, PHP, C++ etc — which newbie developers find really convenient.

Moreover, the language offers a huge standard library to accomplish nearly any task one can think of. This is the reason why Python is referred to as a 'batteries-included' language. There are numerous extensions and packages also available that can really power up this already-powerful beast. We can develop GUIs; perform complex mathematical analysis; visualise data using graphs; process files; query databases; manipulate images; you name it!.

Python has a large developer community which actively works on the language making it even more amazing with every new update. If you would like to learn a programming language, make sure that Python is in your arsenal of skills!

What will you learn in this course?

This course aims at making you fluent with Python and able to code like a real Pythonista. It introduces to many aspects of Python, answers many common questions and puts you at the forefront in developing real-world Python programs.

Being specific, at the end of this course you will know:

  1. How to set up Python on a computer from scratch.
  2. How to write you first program in Python, printing the string 'Hello World'.
  3. What are IDEs, and which Python IDE works best for a given application.
  4. THe basics of the language, including things such as printing stuff, receiving user input, doing math with numbers, working with variables and so on.
  5. The most common data types of Python — integers, floats, Booleans, strings, lists, tuples, sets and dictionaries — and how to use all of them in a program.
  6. What is code commenting and how to effectively comment out pieces of code.
  7. How to use control-flow statements; such as if, elif, else to make selection-based execution; and while and for to make iteration-based execution.
  8. The concept of functions and how to use them to group a block of code under a given name.
  9. How to work with Python numbers — in particular, the basics of numbers, the int and float classes, how to round numbers, generate pseudo-random numbers, and operate on different number systems including binary, hexadecimal and octal.
  10. The str data class in detail, in particular you'll have knowledge on how to create strings; process strings using str methods; what are raw strings; and so on.
  11. The if, elif and else statements, and how they enable selection-based execution of code, by means of checking a condition and proceeding likewise.
  12. How to work with Python lists; specifically, how to create lists; use the concept of mutability; add/remove elements from a list; sort lists perform a bunch of operations on list using list methods.
  13. How to work with Python sets, in particular the set class. You'll be able to create a set; add/remove elements from a set; and most importantly, perform common operations on sets such as union, intersection, difference, superset and subset checks, and much more.
  14. The dict class in Python to create dictionaries — a collection of key-value pairs. You'll know what are dictionary views and how to process items using numerous dictionary methods.

Although we have given roughly a lot of information on our course, you can check out more below in the course overview and explore the details of each unit separately.

Why should you take this course?

There are tons, or maybe even more, JavaScript courses out there on search engines and in that ton we are also a listing, but how are we different from others?

  1. We'll take you through the course in a carefully planned hierarchical manner going from extreme basics to basics, to intermediate and so on. We won't introduce concepts to you before explaining them, or if we do so (very rarely) we will surely explain in them in a more relevant section of the later segment of the course.
  2. We will introduce a couple of coding principles to you along the path of this course, that'll not just make a you a good Python developer, but a better programmer of any language you know or would learn in the future.
  3. We'll answer many common questions arising in the minds of new learners of the Python language, such as why are there two ways to exponentiate an integer a with another integer b: the ** exponentiation operator and the pow() function
  4. We will take small basic quizes from you, between or at the end of every unit, to test your understanding of a given concept, give comments to your scores, give answers to wrong answered questions and thus make you improve as a whole in your skills!


There aren't really any prerequisites for this course.

In this unit, you'll get an introduction to the Python programming language, how to set it up on your computer, and how to get going with it. We'll cover most of the basics of the language including input/output, variables, control-flow statements, functions, and much more.


Here we learn how to work with numbers, in general, in Python. Specifically, we explore the two main numeric classes in Python — int and float; scientific notations; arithmetic operations; rounding numbers and much more. We also explore randomness via the random module and how to work with binary, octal and hexadecimal numbers.


Strings are crucial to programming, and so are they to Python. In this unit, we get ourselves firm-footed on the concept of strings. We see how to create strings; solve character conflict problems; perform replication; and carry out a whole lot of processes on strings using string methods.

Control Flow

Programs can't be cool if the user can't control their flow. In this unit, we explore how to control execution in our Python programs using selection statements — if, elif and else; and using loop statements — for and while.


Here, we see how to work with the most commonly used immutable sequence type in Python — the list class. We start by getting a hands-on experience of lists, before moving on to explore list comprehensions — a superbly quick way to define lists — and list methods. Finally, we end the unit with a detailed chapter on list sorting.


In this unit, we get familiar to one of the most interesting data types in Python — sets. We see how to create sets; perform operations on them such as intersection, union; how to check for subsets, supersets and much more. Lastly, we explore methods of the set class that enable many functionalities on Python sets.


In this unit, we get introduced to dictionaries in Python that can store data with given names. We see how to create dictionaries; when to create them; how to use dictionary views to retrieve given information from a dictionary; a bunch of methods of the dict class and so on and so forth.


In this unit, we introduce ourselves to functions in Python. Out of the box, Python comes with numerous built-in functions to aid in common tasks such as sorting, arithmetic, string manipulation and much more. Here, we explore how functions work and how can we create our own functions. We also learn concepts such as code objects and closures. Lastly we explore lambda functions.

Let's begin learning.
