statistics.stdev and numpy.std code example

Example 1: numpy standard deviation

import numpy as np
data = [68,86,36,57,24,46,32,53] #define some data
data_std = np.std(data) #outputs 19.00493356999703

Example 2: std python

import numpy as np
values=[1,10,100]
print(np.std(values))
values=[1,10,100,np.nan]
print(np.nanstd(values))
