|

Partition.prev_lex (): prev_lex () — bella funzione di libreria Python che restituisce il precedente intero diviso n in ordine lessografico. Questo ordinamento avvolge [n] se la sezione è [1,…, 1].

Sintassi: sympy.combinatorics.partitions.Partition.prev_lex ()

Restituisce: partizione intera precedente, n in ordine lessografico

Codice n. 1: prev_lex () esempio

]


# Codice Python che spiega
# SymPy.prev_lex ()


# import librerie SymPy

da sympy.combinatorics.partitions import Partizione

< p> da sympy.combinatorics.partitions import Inte gerPartition


# Utilizzo del metodo sympy.combinatorics .partitions.Partition.prev_lex ()

p = Partizione intera ([ 312 , 121 , 14 , 5 ])

print ( ’p:’ , p)

print ( ’Previous Integrer:’ , p.prev_lex ())

Logout:

p: [312, 121, 14, 5]

< p> Numero intero precedente: [312, 121, 14, 4, 1]

Codice n. 2: esempio prev_lex ()

< /p>

# Spiegazione del codice Python
# SymPy.prev_lex ()


# import librerie SymPy

from sympy .combinatorics.partitions import Partizione

da sympy. combinatorics.partitions import IntegerPartition


# Utilizzo di sympy.combina metodo torics.partitions.Partiti on.prev_lex ()

p = IntegerPartition ([ 1 , 312 , 121 , 14 ,

34 , 56 , 32 ])

print ( ’p:’ , p)

print ( ’Previous Integrer:’ , p.prev_lex ())

Output:

p: [312, 121, 56, 34, 32, 14, 1]

Intero precedente: [312, 121, 56, 34, 32, 13, 2]
