Python 3 - Overview

Updated: 2020-12-31

Why Python

• Easy to learn
• Simple and compact syntax
• Available everywhere: Linux, macOS, Windows
• Gaining momentum in data science, competing with R

globals() vs locals() vs vars()

• globals() always returns the dictionary of the module namespace
• locals() always returns a dictionary of the current namespace
• vars() returns either a dictionary of the current namespace (if called with no argument) or the dictionary of the argument.
