• Last Updated : 28 Aug, 2019

Subset.rank_binary() : rank_binary() is a sympy Python library function that returns the binary ordered rank.

Syntax :
sympy.combinatorics.subset.Subset.rank_binary()

Return :
the binary ordered rank.

Code #1 : rank_binary() Example

 `# Python code explaining``# SymPy.Subset.rank_binary()`` ` `# importing SymPy libraries``from` `sympy.combinatorics ``import` `Permutation, Cycle``from` `sympy.combinatorics.subsets ``import` `Subset`` ` `# Using from ``# sympy.combinatorics.subset.Subsets.rank_binary()`` ` `# Creating Subset``a ``=` `Subset([``'c'``, ``'d'``], [``'geek'``, ``'for'``, ``'c'``, ``'d'``])`` ` `# rank_binary value``print` `(``"Subset a rank_binary : "``, a.rank_binary)`

Output :

Subset a rank_binary : 3

Code #2 : rank_binary() Example

 `# Python code explaining``# SymPy.Subset.rank_binary()`` ` `# importing SymPy libraries``from` `sympy.combinatorics ``import` `Permutation, Cycle``from` `sympy.combinatorics.subsets ``import` `Subset`` ` `# Using from ``# sympy.combinatorics.subset.Subsets.rank_binary()`` ` `# Creating Subset``a ``=` `Subset([``2``, ``3``, ``4``], [``1``, ``2``, ``3``, ``4``, ``5``])`` ` `# rank_binary value``print` `(``"Subset a rank_binary : "``, a.rank_binary)`

Output :

Subset a rank_binary : 14
