Give me a Python program to angle between two vectors.

Here is a Python program to angle between two vectors

import numpy as np

def angle_between(v1, v2):
    """Returns the angle between two vectors.

    Parameters:
    ----------
    v1: np.ndarray
    v2: np.ndarray

    """
    return np.arccos(np.clip(np.dot(v1, v2) / (np.linalg.norm(v1) * np.linalg.norm(v2)), -1, 1))

# Enter the vectors
v1 = np.array([1, 0, 0])
v2 = np.array([0, 1, 0])

# Calling the function
print((angle_between(v1, v2)))

#Example Output
# 1.5707963267948966

#Remember to inspect code for bugs.
