Python Sympy Subset.prev_binary()用法及代码示例


Subset.prev_binary():prev_binary()是一个sympy Python库函数,它返回先前的二进制有序子集。

用法:
sympy.combinatorics.subset.Subset.prev_binary()

返回:
先前的二进制有序子集。


代码1:prev_binary()示例

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

输出:

Subset a prev_binary : [‘c’]

代码2:prev_binary()示例

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

输出:

Subset a prev_binary : [‘k’]
