How to I compute standard deviation of specific years using dataframe

I have the following dataframe:

Date        Price
2017-01-30  121
2017-03-31  559
2017-06-04  400
2017-09-05  327.26
2017-11-06  32.47
...
2021-03-24  7.62
2021-03-25  107.49
2021-04-26  319.42
2021-05-27  380.77
2021-07-30  32.11

I can’t seem to calculate standard deviation for specific years (e.g. sd for year 2017 only). I have tried to use iloc to specific years while using the .std function but I received type error.

Answer

Or do you mean by?

df['Date'] = pd.to_datetime(df['Date'])
print(df.loc[df['Date'].dt.year.eq(2017), 'Price'].std())
