Python | Pandas series. Day of week

Series.dt can be used to access series values ​​as datetimelike and return multiple properties. Series.dt.weekday Pandas Series.dt.weekday returns the day of the week. The week is assumed to start on Monday, which is 0 and ends on Sunday, which is 6.

Syntax: Series.dt.weekday

Parameter: None

Returns: numpy array

Example # 1: Use the Series.dt.weekday attribute to return the day of the week for a given datetime in the underlying data of this Series object.

# pandas import 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.dt.weekday attribute to return the day of the week for a given date and time in the underlying data of this Series object .

# return day of the week

result = sr.dt.weekday

 
# print the result

print (result)

Output:

As we can see from the output, the Series.dt.weekday attribute successfully accessed and returned day of the week in the base data of this series object.

Example # 2: Use the Series.dt.weekday attribute to return the day of the week for a given datetime in baseline data of this Series object.

# import pandas as pd

import pandas as pd

  
# Create a series

sr = pd.Series (pd.date_range ( ’2012-12-12 12:12 ’ , periods = 5 , freq = ’ M’ ))

 
# Create index

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

< code class = "undefined spaces">  
# set index

sr.index = idx

 
# Print series

print (sr)

Output:

We will now use the Series.dt.weekday attribute to return the day of the week for given date and time in the underlying data of this Series object.

# return the day of the week

result = sr.dt.weekday

  
# print the result

print (result)

Exit:

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