python - 如何使用带有附加条件的 numpy 数组打印偶数字母表

Question

import numpy as np

    a=[1,2,3,4,5,6,7,8,9,10,11,12]
    a=np.array(a)
    b=['a','b','c','d','e','f','g','h','i','j','k','l']
    b=np.array(b)
    # conversion of both list to array
    # want to print even alphabets except 'b'
    print(b[a%2==0 and a!=2])

和条件有什么问题并告诉我如何纠正它？另外我想知道只打印替代字母 - ('d','h','l')

Answer 1

将 numpy 导入为 np

a=[1,2,3,4,5,6,7,8,9,10,11,12]

a=np.array(a)

b=['a','b','c','d','e','f','g','h','i','j','k', 'l']

b=np.array(b)

print(list(b[i-1] for i in a if i%4==0 and i!=1))
