Python

General-purpose scripting and programming language that can be used to develop both automation scripts and software apps — (Text)

• A [____] project can be run via an interpreter or compiled as a binary executable

• Script files identified by .PY extension

• There are several interpreters

  • CPython — Simplest environment to set up for Windows (python.org)

  • PyPy — (pypy.org)

CPython

Reference implementation of the Python programming language. Written in C and Python — (Wiki)

• When using CPython in Windows, there is a

  • Console interpreter (python.exe)

  • Windowed interpreter (pythonw.exe)

• The extension .PYW is associated with pythonw.exe 

True

• It is possible for both to be installed at the same time

  • In Linux,

    • Using the keyword “python” executes a script as version 2

    • “python3” executes a script in the version 3 interpreter

• As of 2020, Python 2 is EOL

  • So scripts should be updated to v3 syntax

True or False: There are two major versions of Python: version 2 and version 3
