Remapping categories

To better understand survey respondents from airlines, you want to find out if there is a relationship between certain responses and the day of the week and wait time at the gate.

The airlines DataFrame contains the day and wait_min columns, which are categorical and numerical respectively. The day column contains the exact day a flight took place, and wait_min contains the amount of minutes it took travelers to wait at the gate. To make your analysis easier, you want to create two new categorical variables:

  • wait_type: 'short' for 0-60 min, 'medium' for 60-180 and long for 180+
  • day_week: 'weekday' if day is in the weekday, 'weekend' if day is in the weekend.

The pandas and numpy packages have been imported as pd and np. Let's create some new categorical data!

  • Create the ranges and labels for the wait_type column mentioned in the description.
  • Create the wait_type column by from wait_min by using pd.cut(), while inputting label_ranges and label_names in the correct arguments.
  • Create the mapping dictionary mapping weekdays to 'weekday' and weekend days to 'weekend'.
  • Create the day_week column by using .replace().
