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


Following is the syntax for log() method ?

import math

math.log( x )

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


  • x ? This is a numeric expression.

Return Value

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


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

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(119L) : ", math.log(119L)
print "math.log(math.pi) : ", math.log(math.pi)

When we run above program, it produces following result ?

math.log(100.12) :  4.60636946656
math.log(100.72) :  4.61234438974
math.log(119L) :  4.77912349311
math.log(math.pi) :  1.14472988585
