# How to calculate the natural logarithm of the Euler Mascheroni constant in Python?

By IncludeHelp Last updated : November 25, 2023

## Euler-Mascheroni Constant

The Euler-Mascheroni constant (also known as the Euler's constant or Mascheroni's constant) is a mathematical constant that is represented by the Greek letter γ (gamma). It is named after the mathematicians Leonhard Euler and Lorenzo Mascheroni, who independently discovered its properties.

## Natural logarithm of the Euler Mascheroni constant

To calculate the natural logarithm of the Euler's constant, get the value of Euler's constant by using the np.euler_gamma() method and then use the np.log() method to get its natural logarithm value.

## Example

Below is a Python program to find the natural logarithm of the Euler Mascheroni constant.

```# Importing numpy library
import numpy as np

# Defining a variable and storing Euler's constant
eu = np.euler_gamma

# Printing the value
print("Euler's constant is :", eu)

# Finding log of Euler's constant
result = np.log(eu)

# Printing the result
print("Log of Euler's constant is :", result)
```

### Output

The output of the above example is:

```Euler's constant is : 0.5772156649015329
Log of Euler's constant is : -0.5495393129816448```
