49 Useful Built-In Functions in Python

In today’s video we’re going to be learning 49 of Python’s most basic (and important) built-in functions. There are 72 in total, but I will only be covering the ones I found myself using the most frequently here.

▶ Follow me on Instagram:

Here are all the timestamps (there were originally supposed to be 50 functions, but apparently I skipped one when recording).

By built in function/constructor u mean the actual built in class. Like when we do int() we are actually calling the int class or in other words creating a instance of the int class and discarding it if not assigns a instance name

√(a² + b²)
Ex :
abs(3 + 4j) = √(3² + 4²) = √(9 + 16) = √25 = 5.0

i must have skipped it but this is for python 3.5+
