NumPyは数値計算ライブラリーです。プログラミング言語Pythonにおいて数値計算を効率的に行うための拡張モジュールです。
import numpy as np
data = [50,50,47,97,49,3,53,42,26,74,82,62,37,15,70,27,36,35,48,52,63,64]
grades = np.array(data)
print(data)
print(grades)
print(type(data), 'x 2:', data * 2)
print('---')
print(type(data), 'x 2:', grades * 2)
Output
