Writing Python code in a basic text editor gets old fast. No autocomplete. No error detection. No debugging tools.
Learning how to use PyCharm fixes all of that.
This JetBrains IDE handles everything from syntax highlighting to package management in one window. It catches bugs before they become problems and cuts your development time significantly.
This guide covers the complete setup: installation, project creation, running scripts, debugging, and version control with Git.
Each section includes exact menu paths and keyboard shortcuts.
Takes about 15 minutes to read. You’ll have a working Python development environment by the end.
Introduction
PyCharm is an integrated development environment built by JetBrains specifically for Python programming.
It handles everything from writing scripts to debugging complex applications.
Developers reach for this IDE when they need code completion, syntax highlighting, and built-in terminal access without switching between tools.
This guide walks through installation, project creation, and running your first Python script. Takes about 15 minutes. Basic familiarity with Python helps but isn’t required.

How Do You Create a New Python Project in PyCharm?
Launch PyCharm, click File > New Project, choose a location for your project folder, select or configure a Python interpreter, then click Create to generate the basic project structure with a virtual environment ready for package installation.
Where Do You Set the Python Interpreter?
During project creation, expand the Python Interpreter dropdown.
Select an existing interpreter or create a new virtual environment. The path looks like C:Python312python.exe on Windows or /usr/bin/python3 on Linux.
Need to change it later? Learn how to add a Python interpreter in PyCharm through Settings.
What Project Structure Does PyCharm Generate?
PyCharm creates these items automatically:
- .idea folder: Stores project configuration and workspace settings
- venv folder: Contains the isolated virtual environment
- External Libraries: References to Python packages and interpreter
The project window on the left shows this file structure. Right-click anywhere to add new Python files.
How Do You Write and Run Python Code in PyCharm?
Create a new .py file in your project directory, write Python code using the editor with autocomplete and error detection, then execute using the Run menu, green play button, or Shift+F10 keyboard shortcut to see output in the built-in console.
Where Do You Create a New Python File?
Right-click your project folder in the Project panel.
Select New > Python File and enter a name without the .py extension (PyCharm adds it).
The file opens immediately in the code editor with syntax highlighting active.
How Do You Execute Your Python Script?
Three ways to run code in PyCharm:
- Right-click method: Right-click inside the editor > Run ‘filename’
- Menu method: Run > Run ‘filename’ from the top menu
- Keyboard shortcut: Press Shift+F10 (Windows/Linux) or Control+R (macOS)
Output appears in the Run panel at the bottom. Errors display with clickable line numbers for quick navigation.
How Do You Use the PyCharm Code Editor?
The editor provides syntax highlighting, real-time error detection, and intelligent code completion that suggests methods, variables, and imports as you type, reducing mistakes and speeding up your software development workflow significantly.
What Keyboard Shortcuts Speed Up Coding?
Essential shortcuts for daily use:
- Ctrl+Space: Trigger code completion manually
- Ctrl+D: Duplicate current line
- Ctrl+/: Toggle line comment in PyCharm
- Ctrl+Shift+F: Search across entire project
- Ctrl+Z: Undo in PyCharm
- Ctrl+B: Go to declaration
How Does Code Completion Work in PyCharm?
Start typing any variable, function, or class name. PyCharm displays suggestions automatically after 1-2 characters.
Press Tab or Enter to accept. Works with installed packages like NumPy, pandas, and Django.
How Do You Debug Python Code in PyCharm?
Set breakpoints by clicking the gutter next to line numbers, run your script in debug mode using Shift+F9, then step through code line by line while inspecting variable values and call stacks in the Debug panel.
Where Do You Set Breakpoints?
Click the empty space (gutter) left of any line number. A red dot appears.
Your script pauses at this line during debug sessions in PyCharm. Click again to remove.
What Information Does the Debug Panel Show?
Three tabs matter most:
- Variables: Current values of all variables in scope
- Watches: Custom expressions you want to monitor
- Call Stack: Function call hierarchy leading to current breakpoint
Use Step Over (F8) to execute line by line; Step Into (F7) to enter function calls.
How Do You Install Python Packages in PyCharm?
Access the package manager through project settings, search for any package from PyPI, click Install to add it to your virtual environment, and import immediately in your code without restarting the IDE.
Where Do You Find the Package Manager?
Navigate to File > Settings > Project > Python Interpreter.
Click the + button above the package list to install packages in PyCharm.
How Do You Install a Package from Requirements.txt?
Open your requirements.txt file in the editor.
PyCharm shows a yellow banner: “Package requirements not satisfied.” Click Install requirements to batch install everything.
Common packages include NumPy, pandas, and pygame.
How Do You Use Version Control in PyCharm?
PyCharm integrates with Git, GitHub, GitLab, and Bitbucket directly, allowing you to commit changes, push to remote repositories, create branches, and resolve merge conflicts without leaving the IDE or using command line tools.
Where Do You Initialize a Git Repository?
Go to VCS > Enable Version Control Integration and select Git.
PyCharm creates a .git folder in your project root. File colors change to indicate source control status.
How Do You Commit and Push Changes?
Two keyboard shortcuts handle most workflows:
- Ctrl+K: Open commit dialog, select files, write message
- Ctrl+Shift+K: Push commits to remote repository
Want to sync with GitHub? Learn how to connect PyCharm to GitHub through Settings > Version Control.
How Do You Configure PyCharm Settings?
Access all IDE preferences through File > Settings on Windows/Linux or PyCharm > Preferences on macOS, where you can customize editor behavior, themes, keymaps, plugins, and project-specific interpreter configurations.
Where Do You Change the Editor Theme?
Path: File > Settings > Appearance & Behavior > Appearance > Theme.
Options include Darcula (dark), IntelliJ Light, and High Contrast. Changes apply immediately.
How Do You Adjust Font Size and Style?
Path: File > Settings > Editor > Font.
Set font family (JetBrains Mono recommended), size (default 13), and line spacing. Enable ligatures for cleaner code symbols.
Quick method: zoom in PyCharm with Ctrl+Mouse Wheel after enabling in Settings > Editor > General.
Verification
Confirm PyCharm works correctly with this test:
- Create a new Python file named
test.py - Type
print("Hello, PyCharm") - Press Shift+F10 to run
- Check Run panel shows:
Hello, PyCharm
If output appears without errors, your installation and interpreter configuration are correct.
Troubleshooting
Python Interpreter Not Detected
Issue: PyCharm shows “No Python interpreter configured” error.
Solution: Go to File > Settings > Project > Python Interpreter > Add Interpreter > System Interpreter, then browse to your Python installation path manually.
Package Installation Fails
Issue: Packages won’t install; pip errors appear.
Solution: Open terminal (Alt+F12), run python -m pip install --upgrade pip, then retry through the package manager. Check pip installation in PyCharm if pip is missing.
Code Completion Not Working
Issue: No autocomplete suggestions appear while typing.
Solution: File > Invalidate Caches > Invalidate and Restart. Also verify interpreter is set correctly for the project.
Project Won’t Run
Issue: Run button grayed out or script doesn’t execute.
Solution: Right-click your .py file > Run. If still failing, check Run > Edit Configurations for correct script path and interpreter.
