Python 中的 SymPy | Partition.next_lex()
原文:https://www . geesforgeks . org/sympy-partition-next _ lex-in-python/
partition . next _ lex():next _ lex()是一个 sympy Python 库函数,返回下一个整数分区,n 按 lexographical 顺序。如果分区是[1,…,1],这种排序将环绕[n]。
语法:sympy . combinations . partitions . partition . next _ lex()
返回:下一个整数分区,n 按字母顺序排列
代码#1 : next_lex()示例
# Python code explaining
# SymPy.next_lex()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.partitions import IntegerPartition
# Using from sympy.combinatorics.partitions.Partition.next_lex() method
p = IntegerPartition([312, 121, 14, 5])
print('p : ', p)
print('\nNext Integrer : ', p.next_lex())
输出:
p : [312,121,14,5]
下一个积分 : [312, 121, 15, 1, 1, 1, 1]
代码#2 : next_lex()示例
# Python code explaining
# SymPy.next_lex()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.partitions import IntegerPartition
# Using from sympy.combinatorics.partitions.Partition.next_lex() method
p = IntegerPartition([1, 312, 121, 14,
34, 56, 32])
print('p : ', p)
print('\nNext Integrer : ', p.next_lex())
输出:
p : [312,121,56,34,32,14,1]
下一个积分 : [312, 121, 56, 34, 32, 15]
