SymPy | Python中的 Subset.iterate_binary()

Subset.iterate_binary() : iterate_binary()是一个 sympy Python库函数，它以 k 步迭代二进制子集。 “k”的值可以是正数或负数。

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

Return :
iterates over the binary subsets by k steps

代码 #1：iterate_binary() 示例

# Python code explaining
# SymPy.Subset.iterate_binary()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
  
# Using from 
# sympy.combinatorics.subset.Subsets.iterate_binary()
  
# Creating Subset
a = Subset(['c', 'd'], ['geek', 'for', 'c', 'd'])
  
# iterate_binary value
print ("Subset a iterate_binary : ", a.iterate_binary(1).subset)

输出 ：

Subset a iterate_binary : [‘for’]

代码 #2：iterate_binary() 示例

# Python code explaining
# SymPy.Subset.iterate_binary()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
  
# Using from 
# sympy.combinatorics.subset.Subsets.iterate_binary()
  
# Creating Subset
a = Subset(['c', 'd'], ['23', 'c', 'd'])
  
# iterate_binary value
print ("Subset a iterate_binary : ", a.iterate_binary(2).subset)

输出 ：

Subset a iterate_binary : [’23’, ‘d’]
