- Students can take advanced Python courses and build real projects with it
Students may build upon the Python and Blockchain knowledge gained in this course and start working on their own Blockchain
Students can dive into Web Development or Data Science with Python
Let me introduce you to this course and to what you'll learn inside of it.
Let's dive into the most important question first: What is Python? In this lecture, we'll take a closer look.
With the theory out of the way it's time to dive into Python. For that we first have to install it so let me guide you through the required steps!
We installed and Python and we are ready to go, so let's actually write our first Python code!
We already wrote our first Python code, but the course comes with a special project where we will be able to apply our new knowledge - The Blockchain. Let's have a closer look at that now!
You know what Python is and how the Blockchain theoretically works but what does the course actually offer you? This lecture will answer that question.
Python is of course not the only programming language you can dive into. Let's take a closer look at some alternatives you have.
Python comes with two different versions available on the market. Let me compare these two versions and show you why learning the latest one, as we will do it throughout the course, is definitely not a bad idea.
There's more than one way of taking a course. Let's find out how you can get the most out of this course in this lecture.
Functions are a very important core concept of any programming language as they allow us to define code which is executed whenever we want. Let me show you the syntax of functions in Python and let's also apply some functions to do the first steps in our Blockchain.
We saw that functions are really powerful, but there is one last important feature we should understand: Keyword arguments (kwargs). These arguments allow us to call a function in a different, more flexible way, so let's see why kwargs can be helpful in our Blockchain!
Before we dive deeper, let's have another look at the general logic of a Blockchain and how transactions should be handled in it. What information should be transferred, how should it be transferred and what about the miners of a new block?
The Blockchain takes shape, time for some theory now: Lists in Python are copied by reference and not by value - what does that mean and which implications does this have for your code? Let me explain the difference between copying "by reference and "by value" in this lecture!
What if we have two equal characters in our string with two different meanings, a single quotation mark (') for example? How can we tell Python when the single quotation mark is supposed to open/ close the string and when it should behave like a normal single quotation mark does, for example when writing 'I'm Max'?
Working with classes means we have different choices regarding types but also regarding the methods and attributes of these classes. Let's have a look at the difference between "Instance", "Class" and "Static Methods" & "Attributes" in this lecture!
Enough about our own modules, let's have a look at third party modules and what we could use these for. For example, we are currently not checking whether our added or mined transactions are valid. Maybe a private and a public key might fix this issue...
- NO prior programming language is required
- You can use whatever operating system you want - macOS, Linux or Windows: It's all covered
Want to learn Python "on the job" whilst building an exciting course project? This course is for you!
Python is probably THE most trending programming language you can learn these days!
It's very popular because it's easy to learn and use, runs on all operating systems and allows you to build a broad variety of programs: Be that web applications, desktop applications, utility scripts or using it for data science and machine learning.
In this course, you'll learn Python from scratch - and you'll do so whilst building your own Blockchain and Cryptocurrency. These are of course also highly trending topics and not a lot of people understand what a Blockchain really is. As a nice side-effect, you will know how a Blockchain works once you completed this course. It's an exciting course project that allows you to learn and apply Python to something you know and you can use.
As written above, Python is both easy-to-use and extremely versatile and powerful at the same time. Certainly not the worst combination. If you check it on Google trends (and compare it to other programming languages), you'll see that it's very popular these days.
It's being used by almost any important company - be that Google, Amazon or Facebook. It's used to run web applications, scripts, desktop programs and machine learning algorithms. This course sets the basics for all these use-cases!
I believe that you learn something best if you directly apply it to a real-world project. And the Blockchain technology is an exciting trend which is there to stay. In this course, you'll learn a lot about the core concepts of the Blockchain and you'll see how Python can be used for the many aspects that make up a Blockchain and Cryptocurrency.
In my opinion, a perfect course project is challenging, interesting, something you know from real-life but also not overly complex. And that's all the case for the Blockchain! It poses some nice challenges where a lot of different Python features can be used to overcome them. It also is something we hear about all the time and yet no one knows how it works. And we can dive into the core Blockchain concepts without spending 100+ hours working on it.
Who's teaching you?
My name is Maximilian Schwarzmüller and I'm a freelance developer. My focus is on web development but I've been working with Python for many years. It's actually one of the first languages I started with when I was 13. I'm the creator of many 5 star bestseller courses here on Udemy and I love diving into new technologies. That's why I had to dive into this whole Blockchain thing when it became more popular and why I chose it as a project for this course.
I can't wait to welcome you on board of this course and I hope you'll enjoy it just as much as I did creating it! :-)
What's in the course?
Great question! Here's a brief summary:
- A summary of Python and the Blockchain technology
- All the base Python syntax you need to know (variables, operators, functions, ...)
- Loops and conditional statements
- More complex data structures like tuples or dictionaries
- A closer look at built-in functions and the standard library Python ships with
- String manipulation
- How to work with files
- Error handling
- Object-oriented programming with classes and inheritance
- Internal & external modules (packages)
- How to spin up an Http server with the Flask package
- Handling Http requests (sending & receiving)
- And more!
What are the course prerequisites?
- NO prior programming knowledge is required
- Very basic knowledge about how a computer works will help you though (but can also be built up whilst you're going through the course)
Is this course for you?
It's for you if ...
- You want to get into programming => Python is a great "first language" since it's easy to learn and very versatile
- You want to broaden your horizon => Are you a web developer? Want to learn something new? Here you go!
- You're interested in Python for web development => This course will teach you Python in general but there are two modules where we'll also dive into web development a bit
- You're interested in the Blockchain technology => You'll learn the core concepts of it as a side-effect of this course!
- You know Python but want to practice it => The course project is challenging and taken from real-life - there probably is no better practice
Does that sound good to you? I'd be honoured to welcome you in this course! :-)
- Anyone interested in learning Python and building a real project with it
- Anyone who's interested in learning about the core internals of a blockchain
- Beginner developers who want to dive into one of the most trending and popular programming languages
