python-scipyHow can I use Python and SciPy to calculate the Jaccard similarity index?

The Jaccard similarity index is a measure of similarity between two sets. It can be calculated using Python and SciPy with the following steps:

1. Import the jaccard_similarity_score function from SciPy's metrics module:

from sklearn.metrics import jaccard_similarity_score

2. Define two sets of data to compare:

set_1 = [1, 2, 3, 4, 5]
set_2 = [3, 4, 5, 6, 7]

3. Calculate the Jaccard similarity index:

jaccard_similarity_score(set_1, set_2)

4. Output:

0.6

The output is a float value between 0 and 1, where 0 indicates no similarity and 1 indicates identical sets.
