list

Utils for handling list.

list.uniq

uniq(seq, key=None)

Removes duplicate elements from a list while preserving the order of the rest.

The value of the optional key parameter should be a function that takes a single argument and returns a key to test the uniqueness.

>>> from pydu.list import uniq
>>> uniq([1, 4, 0, 2, 0, 3])
[1, 4, 0, 2, 3]

list.tolist

tolist(obj)

Convert given obj to list.

If obj is not a list, return [obj], else return obj itself.

>>> from pydu.list import tolist
>>> tolist('foo')
['foo']

list.flatten

flatten(seq)

Generate each element of the given seq. If the element is iterable and is not string, it yields each sub-element of the element recursively.

>>> from pydu.list import flatten
>>> flatten([1, [2, [3, 4]]])
[1, 2, 3, 4]
