【NumPy】値が同じか（equal, not_equal, array_equal）、大きいか（greater, greater_equal）、小さいか（less, less_equal）を判定する方法[Python]

import numpy as np

a = 1
b = 2

print(np.equal(a, b))
print(np.not_equal(a, b))

実行結果
False
True

import numpy as np

a = np.array([1, 2, 3])
b = np.array([3, 2, 1])

print(np.equal(a, b))
print(np.not_equal(a, b))

実行結果
[False  True False]
[ True False  True]

import numpy as np

a = np.array([1, 2, 3])
b = np.array([1, 2, 3])
c = np.array([3, 2, 1])

print(np.array_equal(a, b))
print(np.array_equal(a, c))

実行結果
True
False

import numpy as np

a = 1

c = np.array([1, 2, 3])
d = np.array([3, 2, 1])

print(np.greater(a, b))
print(np.greater_equal(a, b))

print(np.greater(c, d))
print(np.greater_equal(c, d))

実行結果
False
False
[False False  True]
[False  True  True]
