<human>:  gaussian distribution formula.
<bot>: Here is a Python function to gaussian distribution formula

import numpy as np

def gaussian(x, mu, sigma):
  """Returns the value of the Gaussian distribution at x.
  mu is the mean, sigma is the standard deviation.
  """
  return 1 / (sigma * np.sqrt(2 * np.pi)) * np.exp(-(x - mu) ** 2 / (2 * sigma ** 2))

# Enter the values
x = 1
mu = 0
sigma = 1

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

#Example Output
# 0.24197072451914337
