metric accuracy python code example

Example 1: accuracy score sklearn syntax

>>> from sklearn.metrics import accuracy_score
>>> y_pred = [0, 2, 1, 3]
>>> y_true = [0, 1, 2, 3]
>>> accuracy_score(y_true, y_pred)
0.5
>>> accuracy_score(y_true, y_pred, normalize=False)
2

Example 2: sklearn.metrics accuracy_score

// syntax:
// 	- sklearn.metrics.accuracy_score(y_true, y_pred, *, normalize=True, sample_weight=None)
