# Python exp() function

In Python, the `exp()` function is a mathematical function that calculates the exponential value of a number. It is part of the math module in Python, so you need to import the math module to use it.

Here’s the correct syntax for using the `math.exp()` function:

``````import math

result = math.exp(x)
``````

In this syntax, `x` represents the number for which you want to calculate the exponential value. After importing the math module, you can use the `math.exp()` function to calculate the exponential value of `x`, and the result will be stored in the variable `result`.

## Python exp() function example

Here’s an example that demonstrates the usage of `math.exp()`:

``````import math

x = 2.5
result = math.exp(x)

print(result)
``````

Output:

In this example, we import the `math` module. Then, we assign the value 2.5 to the variable `x`. The `math.exp()` function is used to calculate the exponential value of `x`, and the result is stored in the variable `result`. Finally, we print the value of `result`.

When you run this code, the output will be approximately 12.182493960703473. This means that `math.exp(2.5)` returns the exponential value of 2.5, which is approximately 12.182493960703473.

Remember to import the math module before using the `math.exp()` function.
