Utils for handling list.

pydu.list.
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]

pydu.list.
tolist
(obj)¶ Convert given
obj
to list.If
obj
is not a list, return[obj]
, else returnobj
itself.>>> from pydu.list import tolist >>> tolist('foo') ['foo']
-
pydu.list.
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]
