SymPy | Subset.cardinality() in Python

Last Updated : 26 Aug, 2019

Subset.cardinality() : cardinality() is a sympy Python library function that returns the number of all possible subsets.

Syntax : sympy.combinatorics.subset.Subset.cardinality() Return : number of all possible subsets

Code #1 : cardinality() Example

Python3 1=1

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

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

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

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

# cardinality value
print ("Subset a cardinality : ", a.cardinality)

Output :

Subset a cardinality : 16

Code #2 : cardinality() Example

Python3 1=1

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

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

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

# Creating Subset
a = Subset(['c', 'd'], ['23', 'c', 'd'])


# cardinality value
print ("Subset a cardinality : ", a.cardinality)

Output :

Subset a cardinality : 8
