如何检查numpy数组是否在Python序列中?

any 通过适当的测试:

import numpy as np

xs = np.array([1, 2, 3])
ys = np.array([4, 5, 6])
zs = np.array([7, 8, 9])

myseq = (xs, 1, True, ys, 'hello')

def arr_in_seq(arr, seq):
    tp=type(arr)
    return any(isinstance(e, tp) and np.array_equiv(e, arr) for e in seq)

测试:

for x in (xs,ys,zs):
    print(arr_in_seq(x,myseq))
True
True
False

这可能不是最美好或最快速的解决方案,但我认为它是有效的:

import numpy as np


def array_in_tuple(array, tpl):
    i = 0
    while i < len(tpl):
        if isinstance(tpl[i], np.ndarray) and np.array_equal(array, tpl[i]):
            return True
        i += 1
    return False


xs = np.array([1, 2, 3])
ys = np.array([4, 5, 6])

myseq = (xs, 1, True, ys, 'hello')


print(array_in_tuple(xs, myseq), array_in_tuple(ys, myseq), array_in_tuple(np.array([7, 8, 9]), myseq))
