In this tutorial, we will learn how to use the mathematical constant **e** in Python. As many of you may have experienced, calculating the exponential function can often be an important step in various calculations and data analysis tasks. Hence, knowing the method to call this value directly from Python’s **math** module will save you time.

### Step 1: Import the Math module

The first step in Python is to import the **math** module. This module contains a number of mathematical operations, which includes **e**, the base of natural logarithms.

1 |
import math |

### Step 2: Using e in Python

In Python, the value of **e** can be accessed in two major ways.

**Method One:** Directly as a constant

1 |
print(math.e) |

**Method Two:** As an exponent function

1 |
print(math.exp(1)) |

### Step 3: Using the exp function

The **exp(x)** function calculates **e^x**. Here is how you can use it for non-unit values.

1 |
print(math.exp(5)) |

This will give you the value of **e^5**.

## Full Code

1 2 3 4 5 |
import math print(math.e) print(math.exp(1)) print(math.exp(5)) |

## Output

2.718281828459045 2.718281828459045 148.4131591025766

## Conclusion

Being proficient in using **e** and other mathematical constants can aid significantly in your scientific computing tasks. Python, with its concise syntax and extensive libraries, provides an excellent platform for such computations.
