python-numpyHow to check if arrays are equal

import numpy as np

a1 = np.array([[1, 2], [3, 4]])
a2 = np.array([[1, 2], [3, 4]])

is_equal = (a1==a2).all()ctrl + cyoutubegithub

`import numpy as np` load Numpy module for Python	`np.array` declare Numpy array
`a1` first sample array	`a2` second sample array
`is_equal` will contain `True` if `a1` and `a2` are equal	`(a1==a2).all()` will return `True` if all elements of given arrays are equal

Usage example

import numpy as np

a1 = np.array([[1, 2], [3, 4]])
a2 = np.array([[1, 2], [3, 4]])
a3 = np.array([[1, 2], [3, 5]])

print( (a1==a2).all() )
print( (a1==a3).all() )

output

True
False
