<human>:  value on gaussian function.
<bot>: Here is a Python function to value on gaussian

import numpy as np

def gaussian(x, mu, sigma):
 """
 Returns the value of the gaussian function at x.

 :param x:
 :param mu:
 :param sigma:
 """
 return 1 / (sigma * np.sqrt(2 * np.pi)) * np.exp(-(x - mu) ** 2 / (2 * sigma ** 2))

# Enter the values
x = 1
mu = 2
sigma = 3

# Calling the function
print((gaussian(x, mu, sigma)))

#Example Output
# 0.12579440923099774
