PyCharm is a good Python IDE (Integrated Development Environment) program to open, edit, and run Python scripts. It comes with a navigation pane to open a PY file.

The new PyScript project lets you embed Python programs directly in HTML pages and execute them within the browser without any server-based requirements.

Use the Python Interpreter to Run the Program Once the Python file is saved in Notepad, the programmer can run the Python program using the command line and interpreter.
