如何打印numpy.ndarray的内容？

import numpy as np

arr = np.array([[1, 2, 3], [4, 5, 6]])
print(arr)

[[1 2 3]
 [4 5 6]]

import numpy as np

arr = np.array([[1, 2, 3], [4, 5, 6]])
print("Array shape:", arr.shape)
print("Array data type:", arr.dtype)

Array shape: (2, 3)
Array data type: int64

import numpy as np

arr = np.array([[1, 2, 3], [4, 5, 6]])
for row in arr:
    for elem in row:
        print(elem, end=" ")
    print()

1 2 3 
4 5 6

import numpy as np

arr = np.array([[1, 2, 3], [4, 5, 6]])
print("Element at index (0, 1):", arr[0, 1])

Element at index (0, 1): 2
