What are comparison operators in NumPy?

What are comparison operators in NumPy?

Comparison operators in NumPy are used to compare arrays element-wise. They include operators like <, >, <=, >=, ==, and !=.

Can you give me an example of how to use them?

Sure! If you have two NumPy arrays, a = np.array([1, 2, 3]) and b = np.array([2, 2, 1]), you can use a < b to get an array of boolean values: array([ True, False, False]).

What happens if the arrays have different shapes?

If the arrays have different shapes, NumPy will attempt to broadcast them to a common shape. If they can't be broadcasted, it will raise a ValueError.

Are there any other useful functions related to comparison?

Yes! Functions like np.all() and np.any() can be used to evaluate conditions across the entire array.
