[NumPy] asarray()

asarray()

 

리스트 및 튜플을 Numpy 배열로 변환하는 방법

 

import numpy as np

# from list to numpy array
list_sample = [1, 2, 3, 4, 5]
print(list_sample) # [1, 2, 3, 4, 5]

numpy_sample = np.asarray(list_sample)
print(numpy_sample) # [1 2 3 4 5]

# from tuple to numpy array
list_sample = (1, 2, 3, 4, 5)
print(list_sample) # (1, 2, 3, 4, 5)

numpy_sample = np.asarray(list_sample)
print(numpy_sample) # [1 2 3 4 5]

import numpy as np

# from list to numpy array
list_sample = [(1, 2, 3), [4, 5], [(6, 7), (8, 9)]]
print(list_sample) # [(1, 2, 3), [4, 5], [(6, 7), (8, 9)]]

numpy_sample = np.asarray(list_sample)
print(numpy_sample) # [(1, 2, 3), list[4, 5], list[(6, 7), (8, 9)]]
