Python新手错误：TypeError: ‘numpy.ndarray‘ object is not callable

TypeError Traceback (most recent call last) ~\AppData\Local\Temp\ipykernel_7172\1677421385.py in <module> ----> 1 nd(c)

TypeError: 'numpy.ndarray' object is not callable

import numpy as np

nd = np.random.randint(0,100,size=50)

nd

c = nd > 60

c

nd(c) #问题出在这里，应该就中括号

更正为：

nd[c]
