Learn Code Introspection Python Programming

Learn Code Introspection Python Programming: Code introspection is the ability to examine classes, functions and keywords to know what they are, what they do and what they know.

Python provides several functions and utilities for code introspection.

help()
dir() 
hasattr() 
id() 
type() 
repr() 
callable() 
issubclass() 
isinstance() 
__doc__ 
__name__

Often the most important one is the help function since you can use it to find what other functions do.

About the Author: Bernard Aybout

In the land of bytes and bits, a father of three sits, With a heart for tech and coding kits, in IT he never quits. At Magna's door, he took his stance, in Canada's wide expanse, At Karmax Heavy Stamping - Cosma's dance, he gave his career a chance. With a passion deep for teaching code, to the young minds he showed, The path where digital seeds are sowed, in critical thinking mode. But alas, not all was bright and fair, at Magna's lair, oh despair, Harassment, intimidation, a chilling air, made the workplace hard to bear. Management's maze and morale's dip, made our hero's spirit flip, In a demoralizing grip, his well-being began to slip. So he bid adieu to Magna's scene, from the division not so serene, Yet in tech, his interest keen, continues to inspire and convene.
