methods, so we use classes to organize our code. By the same token, we have a concept called package, and we use a package to group related classes.

As our applications grow, we're going to end up with hundreds or even thousands of classes, so we should properly organize these classes into packages. The base package for a Java project is the domain name of your company in reverse.

The code editor might look a little bit intimidating at first, but trust me it's really easy and you're going to learn about it throughout this course. For now, just type a base package for your project; it can be your name or whatever, it doesn't really matter.

Marsh has put together a comprehensive cheat sheet with summary notes that you can download below this video.

IntelliJ is building our application and we can see the result in this little terminal window. So, here's our "Hello World" message. That was our first Java program.

Next, I'm going to explain how Java code gets executed under the hood.

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 It 's considered legacy which means it 's no longer maintained or supported.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.

Contents of mypubspec.yaml - I was told by someone from OneClass that this mypubspec.yaml was invalid. Which didn't make any sense to me.
