In the previous topic, I described how to create a simple script in Python. A text editor was used to create the script. In my case, it was Notepad ++. But there is another way to create programs, which is using various integrated development environments or IDEs.

Like mentioned in https://python.engineering/python-workout-50-ten-minute-exercises/, IDEs provide us with a text editor for typing code, but unlike standard text editors, IDEs also provide full syntax highlighting, auto-completion or smart code hints, the ability to immediately execute the generated script, and much more.

There are a variety of development environments you can use for Python, but one of the most popular is PyCharm by JetBrains. This environment is dynamically developing, constantly updated and available for the most common operating systems - Windows, MacOS, Linux.

Downloading the library

However, it has one important limitation. Namely, it is available in two main options: the paid Professional edition and the free Community. Many basic features are also available in the free Community edition. At the same time, a number of features, such as web development, are only available in the paid Professional.

In our case, we will use the free Community edition. To do this, go to the download page and download the PyCharm Community installation file. After downloading, we will install it.

After the installation is complete, launch the program. When you start it for the first time, the initial window opens.

Let's create a project and for this we select the Create New Project item.

Next, a window will open for us to configure the project. In the Location field, you must specify the path to the project. In my case, the project will be placed in the HelloApp folder. The name of the folder itself will be the name of the project.

It should be noted that PyCharm allows you to delimit project settings. So, by default, the New Environment Using field is selected, which allows you to set the version of the interpreter for a specific project. Then, all additional packages that are installed will only apply to the current project. This is convenient if we create several projects, but each of them works with a specific version of the interpreter. But alternatively, we can also select the Existing Interpreter field and set the path to the interpreter file globally for all projects.

Installation options

In reality, for the first simplest PyCharm application, it doesn't matter how the interpreter is installed. However, in this case, we will leave the New Environment Using checkbox selected by default and under it, in the Base Interpreter field, indicate the path to the interpreter file, the installation of which was considered in Python.

And after setting all the paths, click on the Create button to create the project. Read more in fuzzywuzzy article.
