Challenge #206: Hotel Reservations

Alternative solution!

Continuing on my #SnakingMyWayThruChallenges journey, solved this one in Python (following the same general path that I took with my original Alteryx-only solution... found some cool new tricks with df.query this time, and starting to feel a bit more comfortable with with aggregation functions and manipulating the format of dataframes!). 



PYTHON SCRIPT:

#################################
from ayx import Package

from ayx import Alteryx
import pandas as pd

# Input Alteryx hotel bookings data
df = Alteryx.read("#1")

#################################
# Filter for only those records with reservation status = "Check-Out"
df = df.query('reservation_status == "Check-Out"')

# Format date fields for arrival date and checkout date, and calculate # of days between them
df['arrival_date'] = pd.to_datetime(df['arrival_date_year']+"-"+df['arrival_date_month']+"-"+df['arrival_date_day_of_month'], infer_datetime_format='True')
df['checkout_date'] = pd.to_datetime(df['reservation_status_date'])
df['DaysStayed'] = (df['checkout_date'] - df['arrival_date']).dt.days
df['Number of Reservations'] = 1

# Filter for only those reservations with a duration > 0 days, and format columns
df = df[['arrival_date_month','DaysStayed','Number of Reservations']] \
.query("DaysStayed != '0'") \
.rename(columns = {'arrival_date_month':'Month', 'DaysStayed':'Avg Length of Stay'})

#################################
# Create aggregations of booking data for Avg Length of Stay and Number of Reservations
hotel_bookings = df.groupby('Month', as_index = False).agg({'Avg Length of Stay': "mean", 'Number of Reservations':"sum"})

#################################
Alteryx.write(hotel_bookings,1)

I feel like my solution was mildly convoluted but was able to get the right solution!

Here's my solution

Nice quick one, could shorten it by removing the first filter and the 2nd will take care of the canceled anyway...
