This tutorial goes over the basics of programming in Python. The tutorial will also cover some of Python’s built-in functions, and how to create your own functions.
Python is a very simple language to learn and use, while at the same time being very powerful: It is one of the most used languages by highly productive professional programmers. Python handles a lot of complexity for you, so it is very beginner-friendly in that it allows beginners to focus on learning programming concepts and not have to worry about too much details (at least when compared to languages like C++).
Python is an interpreted high-level programming language for general-purpose programming. Python is a popular choice for beginners, yet still powerful enough to back some of the world’s most popular products and applications from companies like NASA, Google, Mozilla, Cisco, Microsoft, and Instagram, among others.
As web developers, most of us use or have used Python in our workflows. Python is a general-purpose language, which means it can be used to build just about anything, which will be made easy with the right tools/libraries. Professionally, Python is great for backend web development, data analysis, artificial intelligence, and scientific computing.
Many programmers have also used Python to build productivity tools, games, and desktop apps, so there are plenty of resources to help you learn how to do those as well.
Here are a few reasons why Python makes a great first programming language.
It’s simple: Python has a very simple and elegant syntax. It’s much easier to read and write Python programs compared to other languages like C++, Java, C
Python, in my opinion, is the most beautiful programming language out there.
It literally reads like English, making it very easy to learn.
It’s also the fastest growing programming language today, so it’s a great idea to get into!
In this series, we’ll be learning Python from the ground up.
I’ll do my best to explain everything that we’re doing in a way that makes sense and doesn’t overwhelm you.
But if anything doesn’t make sense or you have any questions at all, please leave me a comment and I’ll get back to you as soon as possible (or feel free to email me at [paul@paulsprogrammingnotes.com](http://www.paulsprogrammingnotes.com/contact/)).
Python is a programming language that was created by Guido van Rossum, and released in 1991. Python is a general-purpose programming language, meaning that it can be used to build just about anything, which will be made easy with the right tools/libraries.
As Python has gained a lot of traction in the recent years in Data Science industry, I wanted to outline some of its most useful libraries for data scientists and engineers, based on recent experience. It is by no means an exhaustive list, but it should cover the majority use cases.
There are other libraries out there with similar functionality, but these are offered within the Python ecosystem so they are worth mentioning.
Welcome to the introduction to Python. In this blog post, I will be talking about variables, strings, and integers.
Variables: Variables are nothing but reserved memory locations to store values. This means that when you create a variable you reserve some space in memory. Based on the data type of a variable, the interpreter allocates memory and decides what can be stored in the reserved memory. Therefore, by assigning different data types to variables, you can store integers, decimals or characters in these variables.
Strings: String is sequence of Unicode characters. We can use single quotes or double quotes to represent strings. Multi-line strings can be denoted using triple quotes, ”’ or “””.
Integers: Integer is simply a number that does not have a fractional part and has an unlimited precision (it means we can represent very large integer numbers). We use int() function to convert float to integer. Integers that are too big for your operating system may cause issues if you try to save them as a file (as you should for any projects).
As a kid, I would always pestered my father about why computers did what they did. He would try to explain to me about the hardware and software of computers, but I just didn’t get it. As time went on, I lost interest in computers and became more interested in other things like music and video games.
One day, a few years later, I was at the computer store with my father and a salesman came over to us and asked if we needed help. Knowing that I was very interested in music at the time, he showed me a program called Fruity Loops (now known as FL Studio). This program allowed you to make music using your computer. It was so cool! You could make beats, mix songs together, and create whole songs with just your computer.
I wanted to learn how to use this software right away. But when I opened up the program for the first time it looked like Greek to me! There were so many buttons with strange symbols on them and menus with even more strange words! All I wanted to do was make cool songs like the ones that were included with the program on the demo computers at the store.
So I asked my dad if there was any way that we could learn how to use this software
