standard deviation in python code example

Example 1: standard deviation python

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

Example 2: standard deviation in python numpy

a = [1,2,3,4,5]
numpy.std(a) # will give the standard deviation of a

Example 3: standard deviation in python

import numpy as np
dataset=[13, 22, 26, 38, 36, 42,49, 50, 77, 81, 98, 110]
print('Standard Deviation:', np.std(dataset))

Standard Deviation: 29.694275542602483

Example 4: python running standard deviation

import panda as pd
df = pd.DataFrame(data)
window=5
running_vol=df['x'].rolling(window).std()
