代码 #1：subset_from_bitlist() 示例

# Python code explaining
# SymPy.Subset.subset_from_bitlist()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
  
# Using from 
# sympy.combinatorics.subset.Subsets.subset_from_bitlist()
  
# Creating Subset
a = Subset.subset_from_bitlist( (['geek', 'for', 'c', 'd']), '0101')
  
# subset_from_bitlist value
print ("Subset a subset_from_bitlist : ", a.subset)

输出 ：

Subset a subset_from_bitlist : [‘for’, ‘d’]
