Any kind of "math": Python has you covered

Published 5 days ago • 1 min read

Welcome back to Pandas Daily! Your daily 5-minute boost to becoming confident in Python.

​

Today, we'll introduce Python’s math module—your shortcuts for real calculations.

​

What is the math Module?

A standard Python library that provides mathematical functions - square root, logarithm, trigonometry, you name it. Tasks from rounding prices for invoices to complex analytics for finance or science can be done in a breeze.

​

Why it matters?

You’ll use it for rounding numbers, growth projections, probability calculations, and cleaning messy decimals. Think: estimating trucks for shipments, calculating compound interest, or normalizing data before analysis.

​

Also, we will cover this over multiple days, so feel free to share it with anyone who would like to join. You can brush up previous concepts too.

​

🌟 Loading math library - This loads all functionalities of the module.

In:
import math
Out:

​

🌟 Pre-Defined Constants

In:
print(math.pi) # value of π
print(math.e) # Euler's number
Out:
3.141592653589793
2.718281828459045

​

🌟 Round down numbers using floor(), round up using ceil()

In:
print(math.floor(7.9))
print(math.ceil(7.9))
Out:
7
8

​

🌟 Take square roots

In:
print(math.sqrt(144))
Out:
12.0

​

🐶 How to take square then? - Use pow()

In:
print(math.pow(12, 2))
Out:
144.0

​

📖 pow(a,b) -> a raised to power b

In:
print(math.pow(6, 3))
Out:
216.0

​

🎡 Sizegn does not matter - fabs for absolute values

In:
print(math.fabs(-15.7))
Out:
15.7

​

💔 Break-up Integer and Fraction/Decimal

In:
print(math.modf(123.45))
Out:
(0.44999999999998863, 123.0)

​

❗Factorials are cakewalk

In:
print(math.factorial(5))
Out:
120
