Pycharm – Quick Guide ”; Previous Next Pycharm – Introduction PyCharm is the most popular IDE used for Python scripting language. This chapter will give you an introduction to PyCharm and explains its features. PyCharm offers some of the best features to its users and developers in the following aspects − Code completion and inspection Advanced debugging Support for web programming and frameworks such as Django and Flask Features of PyCharm Besides, a developer will find PyCharm comfortable to work with because of the features mentioned below − Code Completion PyCharm enables smoother code completion whether it is for built in or for an external package. SQLAlchemy as Debugger You can set a breakpoint, pause in the debugger and can see the SQL representation of the user expression for SQL Language code. Git Visualization in Editor When coding in Python, queries are normal for a developer. You can check the last commit easily in PyCharm as it has the blue sections that can define the difference between the last commit and the current one. Code Coverage in Editor You can run .py files outside PyCharm Editor as well marking it as code coverage details elsewhere in the project tree, in the summary section etc. Package Management All the installed packages are displayed with proper visual representation. This includes list of installed packages and the ability to search and add new packages. Local History Local History is always keeping track of the changes in a way that complements like Git. Local history in PyCharm gives complete details of what is needed to rollback and what is to be added. Refactoring Refactoring is the process of renaming one or more files at a time and PyCharm includes various shortcuts for a smooth refactoring process. User Interface of PyCharm Editor The user interface of PyCharm editor is shown in the screenshot given below. Observe that the editor includes various features to create a new project or import from an existing project. From the screenshot shown above, you can see the newly created project Demo and the site-packages folder for package management along with various other folders. You can download the PyCharm Editor and read its official documentation at this link − https://www.jetbrains.com/pycharm/ Pycharm – Installation In this chapter, you will learn in detail about the installation process of PyCharm on your local computer. Steps Involved You will have to follow the steps given below to install PyCharm on your system. These steps show the installation procedure starting from downloading the PyCharm package from its official website to creating a new project. Step 1 Download the required package or executable from the official website of PyCharm https://www.jetbrains.com/pycharm/download/#section=windowsHere you will observe two versions of package for Windows as shown in the screenshot given below − Note that the professional package involves all the advanced features and comes with free trial for few days and the user has to buy a licensed key for activation beyond the trial period. Community package is for free and can be downloaded and installed as and when required. It includes all the basic features needed for installation. Note that we will continue with community package throughout this tutorial. Step 2 Download the community package (executable file) onto your system and mention a destination folder as shown below − Step 3 Now, begin the installation procedure similar to any other software package. Step 4 Once the installation is successful, PyCharm asks you to import settings of the existing package if any. This helps in creating a new project of Python where you can work from the scratch. Note that unlike other IDEs, PyCharm only focusses on working with projects of Python scripting language. Pycharm – Understanding Basics This chapter will discuss the basics of PyCharm and make you feel comfortable to begin working in PyCharm editor. When you launch PyCharm for the first time, you can see a welcome screen with entry points to IDE such as − Creating or opening the project Checking out the project from version control Viewing the documentation Configuring the IDE Recall that in the last chapter, we created a project named demo1 and we will be referring to the same project throughout this tutorial. Now we will start creating new files in the same project to understand the basics of PyCharm Editor. The above snapshot describes the project overview of demo1 and the options to create a new file. Let us create a new file called main.py. The code included in main.py is as follows − y = 3 def print_stuff(): print (“Calling print_stuff”) print (y) z = 4 print (z) print(“exiting print_stuff”) print_stuff() # we call print_stuff and the program execution goes to (***) print(y) # works fine print (z) # NameError!!! The code created in the file main.py using PyCharm Editor is displayed as shown below − This code can be run within IDE environment. The basic demonstration of running a program is discussed below − Note that we have included some errors within the specified code such that console can execute the code and display output as the way it is intended to. Pycharm – Keymaps PyCharm includes various Keymaps to show the most-used commands in the editor. This chapter discusses Keymaps in detail. You can find the list of Keymaps available in the file menu Help -> Keymap Reference as shown in the screenshot given below − You can find the list of Keymaps and the available shortcuts in PDF format as shown below − Note − The default Keymap for Windows and Linux operating systems is default, while in Mac OS the default Keymap is OSX 10.5. You can also view the list of Keymaps available using the Settings option in Windows and Linux Operating system (Preferences in Mac OS) as shown in the screenshot given below − The default Keymap includes various sections for Editor Actions, Main Menu, Tool Windows, External tools, Version Control System, Macros, Quick Lists, Plug-ins and Other options as well.

Pycharm – Interpreters ”; Previous Next PyCharm includes interpreters to create a new project with new features as the way it is needed. You can create a virtual environment in your system as the way you need it. You can also inherit global site packages in the dialog box. Interpreters are available on Python Package Index (PyPI) and can be easily installed and accessed using pip install. Creation of Interpreter For creating an interpreter, it is always recommended to create a new project where desired configurations are managed. Look at the following screenshot for a better understanding − These parameters include − Location − This describes the parameter where virtual environment is created focusing on the location on system. Basic interpreter − It defines the attributes of interpreter. The dialog box also refers to the parameter where an existing virtual interpreter will be taken as an attribute. Once the user adds a new local interpreter, PyCharm will ask the user for the binary of interpreter. In most cases, it is always considered to be a .exe file. In case of Jython, it will be always a .bat file. The details of Project Interpreter and the basic configuration of the existing project demo1 can be seen as shown below − Remember that the interpreter also includes the basic packages which are mandatory for smooth functioning of working of project.
