The idea is to build a function that assigns a schedule $($A$,$ B$,$ or C$)$ to the dates on a cycle of every $2$ days$(24$hrs$)$ switching to the next category in the list. It should repeat until the end date is reached. The starting date is $1/1/2022$ to $12/31/2050.$

The output must be:

$1/1/2022=$ Schedule A

$1/2/2022=$ Schedule A

$1/3/2022=$ Schedule B

$1/4/2022=$ Schedule B

$1/5/2022=$ Schedule C

$1/6/2022=$ Schedule C

And repeat again to Schedule A for $1/7$

You can use this code to make work:

import pandas as pd

from datetime import datetime, timedelta

def generate$\_$schedule$($start$\_$date, end$\_$date$)$:

# List of shifts

shifts $=[\text{'}$A$\text{'},\text{'}$B$\text{'},\text{'}$C$\text{'}]$

# Initialize variables

current$\_$shift$\_$index $=0$

current$\_$date $=$ start$\_$date

date$\_$list $=[]$

shift$\_$list $=[]$

# Loop through the date range

while current$\_$date $<=$ end$\_$date:

# Assign the current shift to the current date

date$\_$list.append$($current$\_$date$)$

shift$\_$list.append$($shifts$[$current$\_$shift$\_$index$])$

# Move to the next shift and date

current$\_$shift$\_$index $=($current$\_$shift$\_$index $+1)\%$ len$($shifts$)$

current$\_$date $+=$ timedelta$($days$=2)$

# Create a DataFrame from the lists

schedule$\_$df $=$ pd$.$DataFrame$(\{\text{'}$Date$\text{'}$: date$\_$list, 'Shift': shift$\_$list$\})$

return schedule$\_$df

# Set the start and end date

start$\_$date $=$ datetime$(2022,1,1)$

end$\_$date $=$ datetime$(2050,12,31)$

generate$\_$schedule$($start$\_$date, end$\_$date$)$
