User interface
When you open a project in PyCharm, the default user interface looks as follows:
Window header contains a set of widgets which provide quick access to the most popular actions: project widget, VCS widget, and run widget. It also allows you to open Code With Me, Search Everywhere, and Settings.
Project tool window on the left side displays your project files.
Editor on the right side, where you actually write your code. It has tabs for easy navigation between open files.
Context menus open when you right-click an element of the interface or a code fragment and show the actions available.
Navigation bar allows you to quickly navigate the project folders and files.
Gutter, the vertical stripe next to the editor, shows the breakpoints you have, and provides a convenient way to navigate through the code hierarchy like going to definition/declaration. It also shows line numbers and per-line VCS history.
Scrollbar, on the right side of the editor. PyCharm constantly monitors the quality of your code by running code inspections. The indicator in the top right-hand corner shows the overall status of code inspections for the entire file.
Tool windows are specialized windows attached to the bottom and the sides of the workspace. They provide access to typical tasks such as project management, source code search and navigation, integration with version control systems, running, testing, debugging, and so on.
The status bar indicates the status of your project and the entire IDE, and shows various warnings and information messages like file encoding, line separator, inspection profile, and so on. It also provides quick access to the Python interpreter settings.

Tool windows
Show/hide:
Tool windows provide functionality that supplements editing code. For example, the Project tool window shows you the structure of your project, and the Run tool window displays the output of your application when you run it.
By default, tool windows are docked to the sides and bottom of the main window. You can arrange them as necessary, undock, resize, hide, and so on. Right-click the title of the tool window or click 
in the title for its arrangement options.
You can assign shortcuts to quickly access the tool windows that you frequently use. Some of them have shortcuts by default. For example, to open the Project tool window, press Alt+1, and to open the Terminal tool window, press Alt+F12. To jump from the editor to the last active tool window, press F12.
Context menus
You can right-click various elements of the interface to see the actions available in the current context. For example, right-click a file in the Project tool window for actions related to that file, or right-click in the editor to see actions that apply to the current code fragment.
Most of these actions can also be performed from the main menu at the top of the screen or the main window. Actions with shortcuts show the shortcut next to the action name.
Popup menus
Popup menus provide quick access for actions related to the current context. Here are some useful popup menus and their shortcuts:
Alt+Insert opens the Generate popup for generating boilerplate code based on the context.
Ctrl+Alt+Shift+T opens the Refactor This popup with a list of contextually available refactorings.
Alt+Insert in the Project tool window opens the New popup for adding new files and directories to your project.
Alt+` opens the VCS Operations popup with contextually available actions for your version control system.
You can create custom popup menus using quick lists of actions that you often use.
Main window
The main window lets you work with a single PyCharm project. You can open multiple projects in multiple windows . By default, the window header displays the name of the project and the name of the currently open file. If there are multiple modules, it will also show the name of the relevant module.
To show the full path to the project and to the current file, select Always show full paths in window header on the Appearance & Behavior | Appearance page of the IDE settings Ctrl+Alt+S.
