如果数组为空,我们可以直接判断数组的元素值为空。 # 检查数组是否为空defis_empty_array(arr):iflen(arr)==0:returnTrueelse:returnFalse 1. 2. 3. 4. 5. 6. 上述代码中,我们定义了一个is_empty_array函数,它接收一个数组作为参数arr。我们使用len函数来获取数组的长度,如果长度为0,则表示数组为空,返...
To check if NumPy array is empty in Python, we can use some functions like the size() function will provide the number of elements in the array, any() provides boolean values if any True value is present inside the array, shape() provides the dimension of the array, and tolist() will...
