Sort#
Alphabetical#
Order a table by the last_name column:
new_table = table.order_by('last_name')
Numerical#
Order a table by the cost column:
new_table = table.order_by('cost')
By date#
Order a table by the birth_date column:
new_table = table.order_by('birth_date')
Reverse order#
The order of any sort can be reversed by using the reverse keyword:
new_table = table.order_by('birth_date', reverse=True)
Multiple columns#
Because Python’s internal sorting works natively with sequences, we can implement multi-column sort by returning a tuple from the key function.
new_table = table.order_by(lambda row: (row['last_name'], row['first_name']))
This table will now be ordered by last_name, then first_name.
Random order#
import random
new_table = table.order_by(lambda row: random.random())
