Python EXPM1

The Python EXPM1 function is one of the Python Math function which is used to calculate the power of E (Where E is Euler’s number approximately equal to 2.71828) and subtracts One from it. In this article we will show you, How to use EXPM1() function in Python Programming language with example.

Syntax of a Python EXPM1 Function

The basic syntax of the EXPM1 Function in Python Programming Language is as shown below:

Or we can simply say math.exp(number) – 1. Please refer Python EXP function for further reference.

Number: It can be a number or a valid numerical expression.

• If the number argument is positive or negative number, EXPM1() function will return the output.
• If the number argument is not a number, EXPM1() function will return TypeError.

Python EXPM1 Function Example

The Python EXPM1 Function is used to calculate the power of Euler’s number E and subtracts One from it. In this example, We are going to check the same with different data types and display the output

PYTHON CODE

OUTPUT

ANALYSIS

1. At the beginning, We declared Python List and Tuple with some random values.
2. Within first two statements, We used the EXPM1() Function with both the Positive integer and negative integer values as arguments.
3. Next two statements, We used the EXPM1() Function on Python Tuple and List items. If you observe the above screenshot, EXPM1() function is working perfectly on them.
4. Next, We tried EXPM1() Function directly on multiple values.
5. In the Last statement, We used the EXPM1() Function on String value. As we said before, this will return TypeError as output.
