Pandas datetime index slicing: sort_index to avoid a KeyError

Pandas datetime index slicing: sort_index to avoid a KeyError

If your Python Pandas dataframe has a datetime index, use a slice to retrieve rows in a certain time period:

taxi_df.loc['2025-11-01':'2025-11-03']

But if the rows are unsorted? You get a KeyError.

Solution:

taxi_df.sort_index().loc['2025-11-01':'2025-11-03']
