Comment(by SimonKing):
Note that, with the patch, `functools.partial` objects can be reasonably
edited as well:
{{{
edit(sage.combinat.partition_algebra.SetPartitionsAk,'vim')
}}}
opens vim at line 31 of sage/combinat/partition_algebra.py:
{{{
def create_set_partition_function(letter, k):
"""
EXAMPLES::
sage: from sage.combinat.partition_algebra import
create_set_partition_function
sage: create_set_partition_function('A', 3)
Set partitions of {1, ..., 3, -1, ..., -3}
"""
from sage.functions.all import floor
if isinstance(k, (int, Integer)):
if k > 0:
return globals()['SetPartitions' + letter + 'k_k'](k)
elif is_RealNumber(k):
if k - math.floor(k) == 0.5:
return globals()['SetPartitions' + letter +
'khalf_k'](floor(k))
raise ValueError, "k must be an integer or an integer + 1/2"
}}}
and indeed that is the underlying definition of `SetPartitionsAk`; see
line 53, which is
{{{
SetPartitionsAk = functools.partial(create_set_partition_function,"A")
}}}
