The logarithm is the inverse of the exponentiation.

With Logarithms, you can easily represent large numbers.

As programmers, when dealing with large numbers, we often need to use logarithms to make things easier.

The python programming language has many built-in logarithmic functions that will allow you to calculate logs with a single line of code.

Let’s look at these logarithmic functions with examples.

Python math.log() function

Before we dive right into the different types of logarithmic methods, let’s first look at how a simple math.log() method works.

Syntax

math.log(x, base)

x: It is mandatory. This numeric expression gives Python the value for which the logarithm should be computed. If you give this value as 0 or a negative number, it will give you a ValueError. If you give a value that isn’t even a number, it will give a TypeError.

base: It is optional. You can give any base of the logarithm you want to give. If you do not specify this parameter, the default value will be equal to ‘e’, which represents the…
