Sort¶
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())
