python-scipyHow can I calculate entropy using Python and SciPy?

Entropy is a measure of disorder in a system. It can be calculated using Python and SciPy with the following steps:

1. Import the entropy module from SciPy:

from scipy.stats import entropy

2. Define a probability distribution. For example, the following code defines a uniform distribution over three values:

p = [1/3, 1/3, 1/3]

3. Calculate the entropy of the distribution:

entropy_val = entropy(p)
print(entropy_val)

Output example

1.584962500721156

4. The result is the entropy of the distribution.
