| | | | | | | | | | | | | |

Series.dt can be used to access series values ​​as datetimelike and return multiple properties. Series.dt.year Pandas Series.dt.year returns an empty array containing the year of the date and time in base data of this series object.

Syntax: Series.dt.year

Parameter: None

Returns: numpy array

Example # 1: Use the Series.dt.year attribute to return the year of the date and time in the underlying data of this Series object.

# import pandas as pd

import pandas as pd


# Create series

sr = pd.Series ([ ’2012-10-21 09:30’ , ’2019-7-18 12:30’ , ’2008-02-2 10:30’ ,

’2010-4-22 09: 25’ , ’ 2019 -11-8 02: 22’ ])


# Create index

idx = [ ’Day 1’ , ’ Day 2’ , ’Day 3’ , ’Day 4’ , ’ Day 5’ ]


# set index

sr.index = idx


# Convert base data to date and time

sr = pd.to_datetime (sr)


# Print series

print (sr)

Output:

We will now use the Series attribute. dt.year to return the year of the date and time in the underlying data of this Series object.

# return year

result = sr.dt.year


# print result

print (result)

Exit :

As we can see from the output, the Series.dt.year successfully accessed and returned the datetime year in the underlying data of this series object.

Example # 2: Use the Series.dt.year attribute to return the year of the date and time in the underlying data of this Series object.

# import pandas as pd

import pandas as pd


# Create series

sr = pd.Series (pd.date_range ( ’2012-12-12 12: 12’ ,

periods = 5 , freq = ’H’ ))


# Create index

idx = [ ’Day 1’ , ’ Day 2’ , ’Day 3’ , ’Day 4’ , ’Day 5’ ]


# set index

sr.index = idx


# Print series

print (sr)

Output:

We will now use the Series.dt.year attribute to return the year of the date and time in the underlying data of this Series object.

# return year

result = sr.dt.year


# print result

print (result)

Output:

Like us we can see from the output, the Series.dt.year attribute successfully accessed and returned the year of the datetime in the underlying data of the given series object.
