Hello Guys, How are you all? Hope You all Are Fine. Today We Are Going To learn about **How can I use “e” (Euler’s number) and power operation in python 2.7** **in Python**. So Here I am Explain to you all the possible Methods here.

Without wasting your time, Let’s start This Article.

## How can I use “e” (Euler’s number) and power operation in python 2.7?

**How can I use “e” (Euler's number) and power operation in python 2.7?**I have modified the equation by replacing

`1/2`

as`0.5`

. Else for Python*<2.7*, we'll have to explicitly type cast the division value to`float`

because Python round of the result of division of two`int`

as integer.**use “e” (Euler's number) and power operation in python 2.7**I have modified the equation by replacing

## Method 1

You can use `exp(x)`

function of math library, which is same as `e^x`

. Hence you may write your code as:

import math x.append(1 - math.exp( -0.5 * (value1*value2)**2))

I have modified the equation by replacing `1/2`

as `0.5`

. Else for Python *<2.7*, we’ll have to explicitly type cast the division value to `float`

because Python round of the result of division of two `int`

as integer. For example: `1/2`

gives `0`

in python 2.7 and below.

## Method 2

Python’s power operator is `**`

and Euler’s number is `math.e`

, so:

from math import e x.append(1-e**(-value1**2/2*value2**2))
