Lesson 2 of 414 steps

Numeric and Boolean Types is a free Python Academy lesson on CoddyKit. This is lesson 2 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Python Academy learning path, and your progress syncs across the web and the CoddyKit app. The Python Academy course includes 4 lessons in total.

Introduction

Python has several numeric types. int holds whole numbers, float holds decimals, and complex holds complex numbers like 3+2j.

Integer Type

int stores whole numbers of arbitrary size: x = 42. No overflow — Python integers grow as needed.
x = 42
print(type(x))

Float Type

float stores 64-bit decimal values: pi = 3.14159. Beware floating-point precision: 0.1 + 0.2 != 0.3 exactly.

Boolean Type

bool is a subclass of int. True equals 1 and False equals 0. You can do: True + True == 2.
print(True + True)
print(type(False))

Arithmetic Operators

+ - * / // % ** are your numeric operators. // is floor division, ** is exponentiation.
print(7 // 2)  # 3
print(2 ** 10) # 1024

Comparison Operators

== != > < >= <= produce booleans. Use is for identity comparison, not == for booleans.
print(10 > 3)
print(10 == 10)

Logical Operators

and, or, not combine boolean expressions. Python short-circuits: False and anything skips the right side.
print(True and False)
print(not True)

Integer Division vs True Division

5 / 2 gives 2.5 (float). 5 // 2 gives 2 (int). Always be explicit about which you need.
print(5 / 2)
print(5 // 2)

abs(), round(), pow()

abs(-7) gives 7. round(3.567, 2) gives 3.57. pow(2, 8) is equivalent to 2**8.
print(abs(-7))
print(round(3.567, 2))

The math Module

import math gives you math.sqrt(), math.pi, math.ceil(), math.floor() for advanced numeric operations.

Boolean Truthiness

Non-zero numbers, non-empty strings and collections are truthy. 0, 0.0, '', [], {}, None are all falsy.

Recap

Python numbers: int (arbitrary precision), float (64-bit), bool (True/False). Key operators: // for floor division, ** for power, and logical and/or/not.
