Python:判断数组中元素是否都满足某条件（比如是否都大于0）_DeniuHe的博客_numpy判断数组内每个数都大于0

import numpy as np
a = np.array([1,2,3,4,5,6])

###The first form
if a.all() > 0:
    print("数组中所有元素都大于0")
else:
    print("数据中有小于等于0的元素")

###The second form
if all(i > 0 for i in a) > 0:
    print("数组中所有元素都大于0")
else:
    print("数据中有小于等于0的元素")import numpy as np
a = np.array([1,2,3,4,5,6])
