 A: You can find various real-life examples in the [CrewAI-examples repository](https://github.com/crewAIInc/crewAI-examples), including trip planners, stock analysis tools, and more.

+# Install PyInstaller
+pip install pyinstaller
+
+# Create the executable
+pyinstaller --onefile your_script.py
+```
+The generated executable will be in the `dist` directory.
