# Python exp

The Python exp math function is used to calculate the power of E, Where E is Euler’s number approximately equal to 2.71828. In this section, we discuss how to use exp function in Python Programming language with example.

The syntax of the exp Function in Python is

`math.exp(number);`

It can be a number or a valid numerical expression that represents the Python exponent value. If the number argument is a positive or negative number, exp function returns the output. And If it is not a number, exp function returns TypeError.

## Python exp Function Example

The exp Function calculates the power of Euler’s number E. In this exp example, We are going to find the exponential check values of different data types and display the output.

```# Python EXP Function

import math

Tup = (1.98, 20.26, 13.05, -40.95 , 0.45) # Tuple Declaration
Lis = [-10.98, 3.65, -9.59, -4.15 , 5.97] # List Declaration

print('EXP() Function on Positive Number = %.2f' %math.exp(1))
print('EXP() Function on Negative Number = %.2f' %math.exp(-1))

print('EXP() Function on Tuple Item = %.2f' %math.exp(Tup))
print('EXP() Function on List Item = %.4f' %math.exp(Lis))

print('EXP() Function on Multiple Number = %.4f' %math.exp(10 + 20 - 15.65))

print('EXP() Function on String Number = ', math.exp('Python'))```
1. Within the first two statements, we used the Python exp Function with both the Positive integer and negative integer values as arguments.
2. Next two statements, We used the exp Function on Tuple and List items. If you observe the above Python screenshot, this Math function is working perfectly on them.
3. We tried Python exponential Function directly on multiple values.
4. In the last statement, we used the Python exponential Function on the String value, and it returns TypeError.
