3. PyCharm Interface Overview
Project Tool Window:
The Project tool window is located on the left side of the PyCharm window. It shows the directory structure of your project, allowing you to navigate and manage your files and folders.
Editor:
The editor is where you write and edit your code. It supports features like syntax highlighting, code completion, and error checking.
Toolbar:
The toolbar contains various buttons for common actions, such as running your code, debugging, and accessing version control.
Status Bar:
The status bar, located at the bottom of the PyCharm window, displays information about your project, such as the current Python interpreter, Git branch, and any warnings or errors.
Tool Windows:
PyCharm has several tool windows that provide additional functionality, such as the Terminal, Python Console, Version Control, and Debugger. You can access these windows from the View menu or using keyboard shortcuts.
4. Writing and Running Python Code
Creating a New Python File:
- Right-click on the project or folder where you want to create the new file.
- Select “New” and then “Python File.”
- Enter a name for the new file and click “OK.”
Writing Code:
Start writing your Python code in the newly created file. PyCharm will provide features like code completion, real-time error checking, and suggestions to improve your code.
Running Code:

Starting the Debugger:
- To start debugging, click the bug icon in the toolbar or use the shortcut Shift + F9.
- PyCharm will run your code and pause execution at the breakpoints, allowing you to inspect variables and step through your code.
Using the Debugger:
- Step Over: Move to the next line of code.
- Step Into: Enter the function call.
- Step Out: Exit the current function.
- Resume Program: Continue running the code until the next breakpoint or the end of the program.
6. Using Version Control
