SymPy | Subset.ksubsets() in Python

Last Updated : 28 Aug, 2019

Subset.ksubsets() : ksubsets() is a sympy Python library function that returns the subsets of size k in lexicographic order.

Syntax : sympy.combinatorics.subset.Subset.ksubsets() Return : the subsets of size k in lexicographic order.

Code #1 : ksubsets() Example

Python3 1=1

# Python code explaining
# SymPy.Subset.ksubsets()

# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset

# Using from 
# sympy.combinatorics.subset.Subsets.ksubsets()

# Creating Subset
a = Subset.ksubsets(4, (['geek', 'for', 'c', 'd']))

# ksubsets value
print ("Subset a ksubsets : ", a.subset)

Output :

Subset a ksubsets : ['for', 'c']

Code #2 : ksubsets() Example

Python3 1=1

# Python code explaining
# SymPy.Subset.ksubsets()

# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset

# Using from 
# sympy.combinatorics.subset.Subsets.ksubsets()

# Creating Subset
a = Subset.ksubsets(4, ([2, 3, 4]))

# ksubsets value
print ("Subset a ksubsets : ", a.subset)

Output :

Subset a ksubsets : [2, 3]
