Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier.

Pandas DatetimeIndex.week attribute outputs the ordinal value of the week for each entries of the DatetimeIndex object. It is similar to the DatetimeIndex.week attribute.

Syntax: DatetimeIndex.week

Return: Index object

Example #1: Use DatetimeIndex.week attribute to find the ordinal value of the week for each entries in the DatetimeIndex object.




# importing pandas as pd
import pandas as pd
  
# Create the DatetimeIndex
# Here 'W' represents Weekly frequency
didx = pd.DatetimeIndex(start ='2000-01-10 06:30', freq ='W',
                            periods = 3, tz ='Asia/Calcutta')
  
# Print the DatetimeIndex
print(didx)


Output :

Now we want to find ordinal value of the week for each entries in the DatetimeIndex object.




# find the ordinal value of the week
