Dada una tupla, la tarea es dividirla en grupos más pequeños de n. Analicemos algunos métodos para realizar una tarea determinada.
Método n. ° 1: usar la función enumerar y rango
# Python code to demonstrate
# how to split tuple
# into the group of k-tuples
# initialising tuple
ini_tuple = (1, 2, 3, 4, 8, 12, 3, 34,
67, 45, 1, 1, 43, 65, 9, 10)
# printing initial tuple
print ("initial list", str(ini_tuple))
# code to group
# tuple into size 4 tuples
res = tuple(ini_tuple[x:x + 4]
for x in range(0, len(ini_tuple), 4))
# printing result
print ("resultant tuples", str(res))
Producción:
lista inicial (1, 2, 3, 4, 8, 12, 3, 34, 67, 45, 1, 1, 43, 65, 9, 10)
tuplas resultantes ((1, 2, 3, 4), (8 , 12, 3, 34), (67, 45, 1, 1), (43, 65, 9, 10))
Método n.° 2: Usar el operador enumerar y modificar
# Python code to demonstrate
# how to split tuple
# into the group of k-tuples
# initialising tuple
ini_tuple = (1, 2, 3, 4, 8, 12, 3, 34,
67, 45, 1, 1, 43, 65, 9, 10)
# printing initial tuple
print ("initial list", str(ini_tuple))
# code to group
# tuple into size 4 tuples
res = tuple(ini_tuple[n:n + 4] for n, i in enumerate(ini_tuple)
if n % 4 == 0)
# printing result
print ("resultant tuples", str(res))
Producción:
lista inicial (1, 2, 3, 4, 8, 12, 3, 34, 67, 45, 1, 1, 43, 65, 9, 10)
tuplas resultantes ((1, 2, 3, 4), (8 , 12, 3, 34), (67, 45, 1, 1), (43, 65, 9, 10))
Método #3: Usar recetas de itertools
# Python code to demonstrate
# how to split tuple
# into the group of k-tuples
# function to group tuple into groups of 4
def grouper(n, iterable):
args = [iter(iterable)] * n
return zip(*args)
# initialising tuple
ini_tuple = (1, 2, 3, 4, 8, 12, 3, 34,
67, 45, 1, 1, 43, 65, 9, 10)
# printing initial tuple
print ("initial list", str(ini_tuple))
# code to group
# tuple into size 4 tuples
res = tuple(grouper(4, ini_tuple))
# printing result
print ("resultant tuples", str(res))

lista inicial (1, 2, 3, 4, 8, 12, 3, 34, 67, 45, 1, 1, 43, 65, 9, 10)
tuplas resultantes ((1, 2, 3, 4), (8 , 12, 3, 34), (67, 45, 1, 1), (43, 65, 9, 10))
