Partition.next_lex():next_lex()是一個sympy Python庫函數,可按字母順序返回下一個整數分區n。如果分區為[1,…,1],則此順序環繞[n]。
用法: sympy.combinatorics.partitions.Partition.next_lex()
返回:下一個整數分區,按字母順序排列n
代碼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())
輸出:
p : [312, 121, 14, 5]
Next Integrer : [312, 121, 15, 1, 1, 1, 1]
代碼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())
輸出:
p : [312, 121, 56, 34, 32, 14, 1]
Next Integrer : [312, 121, 56, 34, 32, 15]
