Question

我对python和计算机科学一般都很陌生，所以也许我错过了一些明显的东西，但如果有人能说出来，我会非常感激！我无法弄清楚我的pyplot直方图功能发生了什么独立于列表，它被要求绘制它返回属性错误。有谁知道我怎么解决这个问题？

运行时：

import matplotlib.pyplot as plt
import numpy as np


test = [np.random.randn() for i in range(100)]

plt.hist(test)
plt.show()

它返回：

      5 test = [np.random.randn() for i in range(10**3)]
      6 
----> 7 plt.hist(test)
      8 plt.show()
