converting numpy array to list code example

Example 1: ndarray to list

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

Example 2: np.array to list

>>> a = np.array([1, 2])
>>> list(a)
[1, 2]
>>> a.tolist()
[1, 2]

Example 3: python numpy array to list

# Basic syntax:
numpy_array.tolist()

# Example usage:
your_array = np.array([[1, 2, 3], [4, 5, 6]])
your_array
--> array([[1, 2, 3],
           [4, 5, 6]])

your_array.tolist()
--> [[1, 2, 3], [4, 5, 6]]

Example 4: list of list to numpy array

>>> lists = [[1, 2], [3, 4]]
>>> np.array(lists)
array([[1, 2],
       [3, 4]])
