最大值，最小值，平均值，标准差的计算

用numpy函数可实现快速计算

n [23]: import numpy as npIn [24]: data = [1, 2, 3]In [25]: np.mean(data)
Out[25]: 2.0In [26]: np.sum(data)
Out[26]: 6In [27]: np.max(data)
Out[27]: 3In [28]: np.min(data)
Out[28]: 1In [29]: np.std(data)
Out[29]: 0.81649658092772603

In [32]: data = np.array([1, 2, 3])In [33]: data.min()
Out[33]: 1In [34]: data.max()
Out[34]: 3In [35]: data.std()
Out[35]: 0.81649658092772603In [36]: data.mean()
Out[36]: 2.0
