Study Notes
Python Maths Basics
- Python is picky about the type of numbers it likes to work with, specifically integers (whole numbers) and floating-point numbers (decimal point numbers).
- Python has a built-in math module that provides various functions for mathematical operations.
Min and Max Functions
- The
min
andmax
functions can be used to find the lowest or highest value in a list. - Example:
x = min(10, 100, 1000)
andy = max(5, 10, 25)
returns the minimum and maximum values in the lists.
Pow Function
- The
pow
function returns the value of x to the power of y. - Example:
pow(5, 4)
returns the value of 5 to the power of 4, which is equivalent to 5 * 5 * 5 * 5.
Sum Function
- The
sum
function returns the sum of all the elements in a list. - Example:
my_list = [1, 2, 3, 4, 5]
andprint(sum(my_list))
returns the sum of the elements in the list.
Round Function
- The
round
function rounds a number to the nearest integer or a specified number of decimal places. - Example:
print(round(3.14159, 2))
returns the value of Pi rounded to 2 decimal places.
Importing Math Library
- To use advanced math functions, you need to import the
math
library. - Example:
import math
allows you to use functions likemath.pi
,math.sin
,math.cos
, and more.
Basic Arithmetic Using Math Library

math
library provides basic arithmetic functions likemath.sqrt
for square roots andmath.pow
for exponentiation.
Trigonometric Functions
- The
math
library provides trigonometric functions likemath.sin
,math.cos
, andmath.tan
for dealing with angles.
Exponential and Logarithmic Functions
- The
math
library provides exponential and logarithmic functions likemath.exp
andmath.log
for calculating exponential and logarithmic values.
Constants
- The
math
library provides constants likemath.pi
andmath.e
for mathematical calculations.
Rounding Functions
- The
math
library provides rounding functions likemath.floor
for rounding down,math.ceil
for rounding up, andmath.round
for rounding to the nearest integer.
Power and Square Root
- The
math
library provides functions for power and square root calculations likemath.pow
andmath.sqrt
.
Absolute Value
- The
math
library provides a function for calculating the absolute value of a number likemath.abs
.
Factorial
- The
math
library provides a function for calculating the factorial of a number likemath.factorial
.
Degrees and Radians
- The
math
library provides functions for converting between degrees and radians likemath.radians
andmath.degrees
.
Hyperbolic Functions
- The
math
library provides functions for hyperbolic calculations likemath.sinh
,math.cosh
, andmath.tanh
.
Challenges
- There are three challenges: decimal doubling, big square root, and shape selector, which require using the math library and basic arithmetic operations.
- The challenges are designed to practice and reinforce the concepts learned in the video.
Python Maths Basics
- Python supports two types of numbers: integers (whole numbers) and floating-point numbers (decimal point numbers).
Min and Max Functions
- The
min
function returns the lowest value in a list. - The
max
function returns the highest value in a list. - Both functions can take multiple arguments.
Pow Function
- The
pow
function raises x to the power of y. - Example:
pow(5, 4)
is equivalent to 5 * 5 * 5 * 5.
Sum Function
- The
sum
function returns the total of all elements in a list.
Round Function
- The
round
function rounds a number to the nearest integer or a specified number of decimal places. - Example:
round(3.14159, 2)
returns Pi rounded to 2 decimal places.
