6. Installing and Configuring PyCharm

1. Introduction​

PyCharm is a popular Integrated Development Environment (IDE) created by JetBrains.
It comes in two editions:

  • Community Edition (free, open-source) → ideal for beginners.
  • Professional Edition (paid) → adds advanced features such as web development and database tools.

For most learners, the Community Edition is sufficient.

2. Downloading PyCharm​

  1. Open your web browser.
  2. Go to the official PyCharm download page:
    https://www.jetbrains.com/pycharm/download/
  3. Choose your operating system (Windows, macOS, Linux).
  4. Download the Community Edition installer.

3. Installing on Windows​

  1. Run the .exe installer.
  2. Follow the setup wizard:
    • Choose installation location.
    • (Optional) Create a desktop shortcut.
    • ✅ Check Add "Open Folder as Project" option.
    • ✅ Add to PATH (recommended).
  3. Click Install and wait for the installation to finish.
  4. Launch PyCharm from the Start Menu.

4. Installing on macOS​

  1. Open the .dmg file you downloaded.
  2. Drag PyCharm CE.app into the Applications folder.
  3. Open it via Spotlight or Launchpad.
  4. (Optional) Add charm command to PATH for opening projects from Terminal:
    • Open PyCharm.
    • Go to Tools → Create Command-line Launcher.
    • Accept default settings.

5. Installing on Linux​

For Ubuntu/Debian:

sudo snap install pycharm-community --classic

For Fedora/RHEL (if Snap not available, use tarball):

sudo tar -xzf pycharm-community-*.tar.gz -C /opt/
cd /opt/pycharm-community-*/
bin/pycharm.sh

For Arch:

yay -S pycharm-community-edition

6. Initial Setup​

  1. Start PyCharm for the first time.
  2. Choose a theme (Light or Dark).
  3. (Optional) Import settings if you used PyCharm before.
  4. Configure font size and keymap if desired.

7. Configuring Python Interpreter​

  1. Create a new project or open an existing folder.
  2. PyCharm will prompt you to set a Python interpreter.
  3. Choose one of the following:
    • Existing interpreter → Use the system Python you installed earlier.
    • Virtual environment → PyCharm can create one for your project.
  4. Confirm the interpreter path (e.g., python3.12).

8. Creating Your First Project​

  1. From the welcome screen, click New Project.
  2. Enter a project name (e.g., HelloPython).
  3. Choose the interpreter.
  4. Click Create.
  5. Inside the project, create a new Python file:
    • Right-click project folder → New → Python File.
    • Name it hello.py.
  6. Type:
print("Hello from PyCharm!")
  1. Right-click the file and choose Run 'hello'.
  2. The output will appear in the Run window:
Hello from PyCharm!

9. Customizing PyCharm​

  • Themes and Fonts: Settings → Appearance & Behavior → Appearance.
  • Keymaps: Choose from IntelliJ, VS Code, or custom keybindings.
  • Plugins: Explore useful plugins (e.g., Markdown support, Git tools, database tools).

10. Troubleshooting​

  • Interpreter not found: Double-check Python is installed and added to PATH.
  • PyCharm feels slow: Increase memory in Help → Change Memory Settings.
  • Projects not opening: Try deleting .idea folder in project directory and reopen.

11. Next Steps​

✅ You now have PyCharm installed and configured.
In the next chapter, we will set up Jupyter Notebook, an interactive environment widely used in data science.
