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
