SymPy | Subset.subset_indices() in Python

Last Updated : 28 Aug, 2019

Subset.subset_indices() : subset_indices() is a sympy Python library function that returns the indices of subset in superset in a list

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

Return :
the indices of subset in superset in a list
if all elements of subset are not in superset. – list is empty

Code #1 : subset_indices() Example

# Python code explaining 
# SymPy.Subset.subset_indices() 
  
# importing SymPy libraries 
from sympy.combinatorics import Permutation, Cycle 
from sympy.combinatorics.subsets import Subset 
  
# Using from  
# sympy.combinatorics.subset.Subsets.subset_indices() 
  
# superset 
super_set = [4, 3, 2, 7] 
  
# Creating Subset 
a = Subset.subset_indices((['geek', 'for', 'c', 'd']), super_set) 
  
# subset_indices value 
print ("Subset a subset_indices : ", a) 

Output :

Subset a subset_indices : []

Code #2 : subset_indices() Example

# Python code explaining 
# SymPy.Subset.subset_indices() 
  
# importing SymPy libraries 
from sympy.combinatorics import Permutation, Cycle 
from sympy.combinatorics.subsets import Subset 
  
# Using from  
# sympy.combinatorics.subset.Subsets.subset_indices() 
  
# superset 
super_set = [4, 3, 2, 7] 
  
# Creating Subset 
a = Subset.subset_indices(([2, 3, 4]), super_set) 
  
# subset_indices value 
print ("Subset a subset_indices : ", a) 

Output :

Subset a subset_indices : [2, 1, 0]
