Overview
Unique Iteration Utilities.
Functions:
| Name | Description |
|---|---|
uniquelist |
Return unique list. |
uniquetuple |
Return unique tuple. |
unique |
Iterate over |
Return unique list.
uniquelist([1, 5, 2, 3, 3, 6, 7, 2, 3]) [1, 5, 2, 3, 6, 7]
The key callback allows to refine the duplicate detection:
uniquelist([(5, 'a'), (2, 'b'), (3, 'a'), (4, 'b'), (3, 'a')]) [(5, 'a'), (2, 'b'), (3, 'a'), (4, 'b')] uniquelist([(5, 'a'), (2, 'b'), (3, 'a'), (4, 'b'), (3, 'a')], key=lambda item: item[1]) [(5, 'a'), (2, 'b')]
Return unique tuple.
uniquetuple([1, 5, 2, 3, 3, 6, 7, 2, 3]) (1, 5, 2, 3, 6, 7)
The key callback allows to refine the duplicate detection:
uniquetuple([(5, 'a'), (2, 'b'), (3, 'a'), (4, 'b'), (3, 'a')]) ((5, 'a'), (2, 'b'), (3, 'a'), (4, 'b')) uniquetuple([(5, 'a'), (2, 'b'), (3, 'a'), (4, 'b'), (3, 'a')], key=lambda item: item[1]) ((5, 'a'), (2, 'b'))
Iterate over iterable and ensure that every item is just returned once.
