Version History¶
3.2.0¶
- New itertools:
lstrip()
,rstrip()
, andstrip()
(thanks to MSeifert04 and pylang)islice_extended()
- Improvements to existing itertools:
- Some bugs with slicing
peekable()
-wrapped iterables were fixed
- Some bugs with slicing
3.1.0¶
- New itertools:
numeric_range()
(Thanks to BebeSparkelSparkel and MSeifert04)count_cycle()
(Thanks to BebeSparkelSparkel)locate()
(Thanks to pylang and MSeifert04)
- Improvements to existing itertools:
- A few itertools are now slightly faster due to some function optimizations. (Thanks to MSeifert04)
- The docs have been substantially revised with installation notes, categories for library functions, links, and more. (Thanks to pylang)
3.0.0¶
- Removed itertools:
context
has been removed due to a design flaw - see below for replacement options. (thanks to NeilGirdhar)
- Improvements to existing itertools:
side_effect
now supportsbefore
andafter
keyword arguments. (Thanks to yardsale8)
- PyPy and PyPy3 are now supported.
The major version change is due to the removal of the context
function.
Replace it with standard with
statement context management:
# Don't use context() anymore
file_obj = StringIO()
consume(print(x, file=f) for f in context(file_obj) for x in u'123')
# Use a with statement instead
file_obj = StringIO()
with file_obj as f:
consume(print(x, file=f) for x in u'123')
2.6.0¶
- New itertools:
adjacent
andgroupby_transform
(Thanks to diazona)always_iterable
(Thanks to jaraco)- (Removed in 3.0.0)
context
(Thanks to yardsale8) divide
(Thanks to mozbhearsum)
- Improvements to existing itertools:
ilen
is now slightly faster. (Thanks to wbolster)peekable
can now prepend items to an iterable. (Thanks to diazona)
2.5.0¶
- New itertools:
distribute
(Thanks to mozbhearsum and coady)sort_together
(Thanks to clintval)stagger
andzip_offset
(Thanks to joshbode)padded
- Improvements to existing itertools:
peekable
now handles negative indexes and slices with negative components properly.intersperse
is now slightly faster. (Thanks to pylang)windowed
now accepts astep
keyword argument. (Thanks to pylang)
- Python 3.6 is now supported.
2.4.1¶
- Move docs 100% to readthedocs.io.
2.4¶
- New itertools:
accumulate
,all_equal
,first_true
,partition
, andtail
from the itertools documentation.bucket
(Thanks to Rosuav and cvrebert)collapse
(Thanks to abarnet)interleave
andinterleave_longest
(Thanks to abarnet)side_effect
(Thanks to nvie)sliced
(Thanks to j4mie and coady)split_before
andsplit_after
(Thanks to astronouth7303)spy
(Thanks to themiurgo and mathieulongtin)
- Improvements to existing itertools:
chunked
is now simpler and more friendly to garbage collection. (Contributed by coady, with thanks to piskvorky)collate
now delegates toheapq.merge
when possible. (Thanks to kmike and julianpistorius)peekable
-wrapped iterables are now indexable and sliceable. Iterating throughpeekable
-wrapped iterables is also faster.one
andunique_to_each
have been simplified. (Thanks to coady)
2.3¶
- Added
one
fromjaraco.util.itertools
. (Thanks, jaraco!) - Added
distinct_permutations
andunique_to_each
. (Contributed by bbayles) - Added
windowed
. (Contributed by bbayles, with thanks to buchanae, jaraco, and abarnert) - Simplified the implementation of
chunked
. (Thanks, nvie!) - Python 3.5 is now supported. Python 2.6 is no longer supported.
- Python 3 is now supported directly; there is no 2to3 step.
2.2¶
- Added
iterate
andwith_iter
. (Thanks, abarnert!)
2.1¶
- Added (tested!) implementations of the recipes from the itertools documentation. (Thanks, Chris Lonnen!)
- Added
ilen
. (Thanks for the inspiration, Matt Basta!)
2.0¶
chunked
now returns lists rather than tuples. After all, they’re homogeneous. This slightly backward-incompatible change is the reason for the major version bump.- Added
@consumer
. - Improved test machinery.
1.1¶
- Added
first
function. - Added Python 3 support.
- Added a default arg to
peekable.peek()
. - Noted how to easily test whether a peekable iterator is exhausted.
- Rewrote documentation.
1.0¶
- Initial release, with
collate
,peekable
, andchunked
. Could really use better docs.
