代码 #1：bitlist_from_subset() 示例

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

输出 ：

Subset a bitlist_from_subset : 0011
