SymPy | Python中的 Subset.iterate_graycode()

Subset.iterate_graycode() : iterate_graycode()是一个 sympy Python库函数，它迭代 k 步以获取相应的格雷码。

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

Return :
iterates over the k steps to get the respective Gray codes

代码 #1：iterate_graycode() 示例

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

输出 ：

Subset a iterate_graycode : [‘c’]

代码 #2 : iterate_graycode() 示例

# Python code explaining
# SymPy.Subset.iterate_graycode()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
  
# Using from 
# sympy.combinatorics.subset.Subsets.iterate_graycode()
  
# Creating Subset
a = Subset(['c', 'd'], ['23', 'c', 'd'])
  
# iterate_graycode value
print ("Subset a iterate_graycode : ", a.iterate_graycode(3).subset)

输出 ：

Subset a iterate_graycode : [’23’, ‘c’, ‘d’]
