Description : The method log( ) returns natural logarithm of x, for x > 0.
Syntax : 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.
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 log() method.
# !/usr/bin/python
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)
This will produce the 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
