The exp () method used to calculate the index in Python

This article mainly introduces the exp () method used to calculate the index in Python, which is a basic method required for getting started with Python. For more information, see

Returns x: ex.

Syntax

The following is the syntax of the exp () method:

?

1 2 3

Import math   Math. exp (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

Returns x: ex.

Example

The following example shows the use of the exp () method.

#! /Usr/bin/python Import math # This will import math module   Print "math. exp (-45.17):", math. exp (-45.17) Print "math. exp (100.12):", math. exp (100.12) Print "math. exp (100.72):", math. exp (100.72) Print "math. exp (119L):", math. exp (119L) Print "math. exp (math. pi):", math. exp (math. pi)

When we run the above program, it will produce the following results:
