Create Executable from Python Script using Pyinstaller

 PyInstaller works by reading your Python program, analysing all of the imports it makes, and bundling copies of those imports with your program.

PyInstaller reads in your program from its entry point. For instance, if your program’s entry point is myapp.py, you would run pyinstaller myapp.py to perform the analysis.

PyInstaller can detect and automatically package many common Python packages, like NumPy, but you might need to provide hints in some cases.

After analyzing your code and discovering all the libraries and modules it uses, PyInstaller then generates a 'spec file'.

 A Python script with the extension. spec, this file includes details about how your Python app needs to be packed up.

PyInstaller can be installed using following command.

pip install pyinstaller
