A package for analyzing permutation patterns.
Project description
permpy
A Python Permutations Class
Contains Various tools for working interactively with permutations. Easily extensible.
Examples:
>>> import permpy as pp
>>>
>>> p = pp.Perm.random(8)
>>> p
5 4 7 1 6 2 3 8
>>> p.cycles()
'( 6 2 4 1 5 ) ( 7 3 ) ( 8 )'
>>> p.order()
10
>>> p ** p.order()
1 2 3 4 5 6 7 8
>>>
>>> S = pp.PermSet.all(6)
>>> S
Set of 720 permutations
>>> S.total_statistic(pp.Perm.num_inversions)
5400
>>> S.total_statistic(pp.Perm.num_descents)
1800
>>>
>>> A = pp.AvClass([ 132 ])
>>> A
[Set of 0 permutations,
Set of 1 permutations,
Set of 2 permutations,
Set of 5 permutations,
Set of 14 permutations,
Set of 42 permutations,
Set of 132 permutations,
Set of 429 permutations,
Set of 1430 permutations]
