代码# 1:unlank _ binary()示例

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

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

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

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

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

输出:

子集 a unlank _ binary:[' for ']

代码# 2:unlank _ binary()示例

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

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

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

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

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

输出:

子集 a unlank _ binary:[2]
