Python Programming Tutorial

In this Python tutorial, you'll learn everything you need to start programming in Python. This tutorial is perfect for data science, machine learning, and web development. No prior knowledge in Python or programming is required as everything will be taught from scratch. I'm Mosh Hamadani, and I've taught millions of people how to code through this channel. If you're new here, make sure to subscribe as I upload new videos every week. Let's jump in and get started.

 

What is Python?

Python is a multipurpose programming language that can be used for a variety of different tasks, such as automation, web development, and data science.

 

You can use Python in automation to automate repetitive tasks and save time and increase productivity.

You need to install a code editor to write your own Python code.

You can build amazing websites powered by Python.

We'll be using PyCharm as our code editor in this tutorial. When you open PyCharm for the first time, you have to configure a few settings, but we can skip that for now and set defaults. Let's create a new project and collapse the project window to give more space. We can then print a message on our application window.

 

Running Python Code

To run Python code in PyCharm, we go to the run menu and select run, or use the shortcut (ctrl+shift+r on a Mac). Then select the app to run, and the output will appear in the terminal window. Python is case sensitive so make sure to use the correct case when coding. We can declare variables, such as age and price, and assign them values. Python also has boolean values that can be true or false.

 

Now let's start coding!

 

    age = 30

    print(age)

    price = 19.95

    print(price)  

python is nowadays the most popular programming language but you can say it is the fastest growing programming language nowadays. The concept of python came into picture in 1989 and even java was you know the concept of java or python i 'll pronounce it as python right okay now see python is being used right now the main areas are machine learning data science artificial intelligence. White has become so popular because first thing is it is easy to learn easy to understand and it has wide range of applications i have told you in how many areas almost in every area it 's been used in almost every area. The big giants companies are using this language maybe the main language or supportive type of language as a support language. python is multi-paradigm language it is general purpose language almost in every field for making everything you can use this language. python is interpreted language without compiled language and is open source so that is why it is having a huge community and rich library many ill you know inbuilt packages modules functions.

The main areas where Python is being used are in software development, web development, data science,, artificial intelligence,, game development, and mobile apps..NK] Big giants companies are using Python as a support language in their research and development fields.. [UNK] is an easy to-understand, relatively low-level language that is suited for data analysis, software, development,, and game programming..NK] also has a wide range of applications in fields like artificial intelligence and machine learning.. 1.. Python is a general purpose, interpreted language. 2.. Python has a rich library with many preexisting functions and modules that can be used in programs without having to write them from scratch. 3.. Python is a popular language for data science and machine learning due to its built-in libraries and modules.. 4. Python has a large community of developers who can answer questions and help you out if you are struggling with using. It.

There are lots of career opportunities for this in this field for this language. There are many career opportunities and average salary is also high like it 's from 8 to 12 per nm so that is why it is so popular and i'm sure you are aware about now this language some features who are using it the application areas of python and all. In the next video we will see history of this language first.

Computer

Python is the world 's fastest growing and most popular programming language. People from different disciplines use Python for a variety of different tasks. With Python you can solve complex problems in less time with fewer lines of code. You can also use Python to build web, mobile and desktop applications as well as software testing or hacking. Python is a multi-purpose language with a simple, clean, and beginner-friendly syntax. It has a large ecosystem of libraries, frameworks and tools which means whatever you do it is likely that someone else has done it before. The average Python developer earns a whopping 116,000 dollars a year.

Mosh is a software engineer with two decades of experience and I 've taught over 3 million people how to code. He has designed this Python course for anyone who wants to learn Python. In this tutorial I 'm going to show you how to download and install Python on your computer. You will learn how to use Python in machine learning or artificial intelligence. All the materials you 're going to learn in this course will apply to the latest version of Python as well. At the time of recording this video the latest. version is python 3. 7. 2. Chances are in the future , when you are watching this tutorial there is a newer version of. Python available. The first time we run pycharm we 're going to get this warning because this is an application that we download from the internet. So let 's go ahead and open it every time you open it, click on create new project. Make sure that base interpreter is set to Python 3. Mac computers come with an older installation of Python, that 's Python 2. It 's considered legacy which means it 's no longer maintained or supported. So by convention, all Python files should have this py extension.

In this Python tutorial , we 're gong to take this program to the next level and make it more interesting. So I 'm going to show you how to draw a dog hair. As part of this tutorial you will learn how Python code gets executed and you will also learn about a few programming terms. In the future as you learn more Python you 'll be able to build applications that have a graphical user interface. With this piece of code we can draw 10 asterisks on the terminal. Python interpreter tries to execute line 4 when it executes line 4. It will evaluate the code that we put in between parenthesis. and before the parenthesis , add a space , once again , add an asterisk , space , 10. So let 's run this program one more time , there you go. Are you excited to learn Python and get started on this career path ? If you are, I would encourage you to make a commitment and spend 2 hours every day practicing python. Use the comment box below and let me know why you are learning Python , what do you want to do with it ? What 's your dream job ? I would love to hear your story.

Python interpreter executes our code line by line from the top. On the second line we can update the value of this price variable , so we can reset it to a new value like 20. On line 2, we can define another variable called rating and set it to number 4. 9. Now note that Python is a case sensitive language. Python is sensitive to lower case and upper case letters. In this tutorial, I 'm going to show you how to receive input from the user. So we 're going to write a small program that asks the user 's name and then we 'll print a greeting message customized for that user. In Python we also have functions for common tasks such as printing messages, receiving input , and so on. Mosh has created a cheat sheet with summary notes to review the materials in this course. The link is below this video. So I have done my best to create the best possible Python course on Youtube. And I really appreciate it if you support my hard work by liking this video and sharing it with others.
