All,
My dataset looks like following, and I Would like to add one column which can convert my last column i.e Day_of_The_week to Mon, Tue, Wed.
Note: Day_of_the_week include 5 days : Mon,Tue,Wed,Thurs,Fri. I checked link but couldn't figure out how to implement in my dataframe
I would like to convert my pandas dataframe as below:
Being a newbie to python,if you could provide explanation, that will be great!

calendar.day_name + pd.Series.map
You can construct a dictionary and then map your integer series to a list of day strings:
import pandas as pd
from calendar import day_name
from collections import deque
df = pd.DataFrame({'Day_of_the_week': [2, 3, 4, 4, 5, 6, 6]})
days = deque(day_name)
days.rotate(df['Day_of_the_week'].iat[0]) # rotate days
days_map = dict(enumerate(days)) # construct dictionary
df['Day_Factor'] = df['Day_of_the_week'].map(days_map)
print(df)
Day_of_the_week Day_Factor
0 2 Monday
1 3 Tuesday
2 4 Wednesday
3 4 Wednesday
4 5 Thursday
5 6 Friday
6 6 Friday

Thanks! The dictionary key's assigned 0 to Friday. I would like to assign key 6 to Friday. Is there a way to do that ? I would like my dictionary to start with 2 as Monday and ends at Key 6- Friday.

@biggboss2019, Yes, as you can see that's what my logic does, you are rotating days by 2 days. Since theday_namehas Monday at index 0, but you want it at index 2. To hardcode this, use2instead ofdf['Day_of_the_week'].iat[0].
