Python 3 - Number log() Method

---

Description

The log() method returns the natural logarithm of x, for x > 0.

Syntax

Following is the syntax for the log() method −

import math

math.log( x )

Note − This function is not accessible directly, so we need to import the math module and then we need to call this function using the math static object.

Parameters

x − This is a numeric expression.

Return Value

This method returns natural logarithm of x, for x > 0.

Example

The following example shows the usage of the log() method.

#!/usr/bin/python3
import math   # This will import math module

print ("math.log(100.12) : ", math.log(100.12))
print ("math.log(100.72) : ", math.log(100.72))
print ("math.log(math.pi) : ", math.log(math.pi))

Output

When we run the above program, it produces the following result −

math.log(100.12) :  4.6063694665635735
math.log(100.72) :  4.612344389736092
math.log(math.pi) :  1.1447298858494002
