The log () method used to calculate the logarithm in Python
This article mainly introduces the log () method used to calculate the logarithm in Python. It is a required method for getting started with Python. For more information, see
The log () method returns the natural logarithm of x, for x> 0.
Syntax
The syntax of the log () method is as follows:

Import math Math. log (x) |
Note: This function cannot be directly accessed. Therefore, we need to import the math module and then use the static object of math to call this function.
Parameters
- X -- this is a numeric expression.
Return Value
This method returns the natural logarithm of x, for x> 0.
Example
The following example shows how to use the 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) |
When we run the above program, it will produce the following results:
