Alright, Guys welcome to this Python series , today we talk about Choosing an IDE.So lets know how to be an efficient at programming with Python?The question can be posed for any programming language really, and so the answer is usually going to be same.
I mean feel free if you want to, to open up notepad on Windows or you know some basic text editor and write a script and go over to the terminal and command prompt and run it, however that's not efficient for a variety of reasons. So, what we're going to be using is an IDE, which stands for integrated development environment, and we're going to be using Jetbrains, PyCharm. Now, PyCharm is free for, I spelled that wrong just go to Google, search PyCharm, and click on the link there which is from jet brains.com, and you can download it.
Now when you get to the download screen you're going to get a professional or community version, choose the community version that is free, it's completely fully featured as far as i can tell, and that's the one that we're going to be using in this Post. Now alternatively I mean you can go have a look at other IDEs for Python, but I find that this one it just works really well,it's simple, and it does everything that we need it to do, and it also has some advanced features which we may look at some point in the future.
Download;
So, go ahead download the installer for your platform, it does require Java as well, so you can just open up Google and type download Java, and it's going to take a java.com/download if you click that link, just click download the appropriate version for your system, and once you have that installed then you can install PyCharm. So, this is going to be the first screen that you see every time you start up PyCharm. We're going to create a new project, it's going to be pure Python, now there's also other options here if you want to start a Django project, etc., but we're just going to start a Python project here and we're going to choose version 3.5.1 which is also going to tell the IDE here where to find the binary files to run Python.
Project Making;
Now, we're also going to name the project here, so first program, and this is going to be the name of our project. It's going to create a folder called first program and this is how we're going to identify it within here.So, along the left-hand side here this is the project view so let's go ahead and right click and create a new file.We're just going to choose a Python file and i'm going to name it main, which is going to name it main.py, and here we can start typing our script. So, again i'm just going to use the hello world example, and that's all it's going to be. I'm going to save it, keyboard shortcuts are going to take you a long way if you're going to become a programmer, so I expect you know some already, if you don't on Windows Linux control + S saves the file and on OS 10 its command + S so you don't have to always go through the menus and stuff, but let's have a look through the menus. If you want to create a new project, a new file, or directory you can open one etcetera.
you can actually access the settings by going to default settings for this project, and a bunch of different options down here that we don't really need. If you go to edit you're going to see you can undo and it's also going to show you the corresponding keyboard shortcuts for each one of these options, so this is command + Z and that's going to undo whatever action I previously did, this is also going to be useful if you're going to become a professional programmer. Same is true for copy, paste, find. We're going to be discussing find at some point, I mean it's a pretty powerful command you can find not only in the current file but your entire project if you want to look for instances of variable or string or something you can actually search through the entire root directory of this project if you want. If you go to view and go tool windows here is what we're looking at here project if we select that it's going to, it should hide that, yeah, so it hid the project sidebar, so we're going to leave that open.If you have version control setup this will not be disabled and you can use that to perform first control actions.Now open Python Console and here we run the actual Python Code.
If we wanted to say 5+5 you know and it's going to return that so this is the interpreter itself, however if we want to actually open terminal we can open a terminal here and here we can just type python3, main.py and it's going to run what we have up in this file right here. Now additionally we have a run right here. We can set up run, a run configuration here, to actually every time we hit the run it's going to automatically run our project so let's go ahead and hit the plus sign, choose python, and it's gonna be called a Python run,script is going to be python3 or the script is going to be the the actual python script that we want run so it's going to be main.py, script parameters this is if we're passing in any arguments or anything we're not going to it's already found the Python interpreter.
This is going to be interpreter options we're not going to be using any, and that's all that we need to do. So, let's go ahead and click apply and then run, and it's going to run the script, output that, and then it says it finished with exit code zero which is completely normal. So, every time you want to run if you have this little section opened here just hit that play button, the Run button there, it's going to run the code in real time. So, make changes, hit ctrl + S,and then run the code right there, this is the most efficient way to run a program in an IDE, you know, you don't have to switch back and forth between windows and stuff. So, this is the primary reason that we're going to be using this IDE for the sake of this course.
Again, feel free to have a look at some others but I recommend if you're a complete novice to any of this just follow along exactly with what I'm doing and you shouldn't have a problem. However, if you do there's a discussion section to the right of this Post, use it, let me know if you have any trouble,and I'll try to clear it up. So, with all that said we are finally ready to actually get in to the language itself.
