Programa Python para convertir tupla en lista agregando la string dada después de cada elemento

Dada una Tupla. La tarea es convertirlo a Lista agregando la string dada después de cada elemento.

Ejemplos:

Input : test_tup = (5, 6, 7), K = "Gfg" 
Output : [5, 'Gfg', 6, 'Gfg', 7, 'Gfg'] 
Explanation : Added "Gfg" as succeeding element.

Input : test_tup = (5, 6), K = "Gfg" 
Output : [5, 'Gfg', 6, 'Gfg'] 
Explanation : Added "Gfg" as succeeding element.

Método #1: Usar la comprensión de listas

En esto, construimos una tupla de cada elemento de la tupla con un elemento siguiente y luego ejecutamos un ciclo anidado para aplanar cada tupla construida utilizando la comprensión de listas.

# Python3 code to demonstrate working of
# Convert tuple to List with succeeding element
# Using list comprehension
 
# initializing tuple
test_tup = (5, 6, 7, 4, 9)
 
# printing original tuple
print("The original tuple is : ", test_tup)
 
# initializing K
K = "Gfg"
 
# list comprehension for nested loop for flatten
res = [ele for sub in test_tup for ele in (sub, K)]
 
# printing result
print("Converted Tuple with K : ", res)

Producción:

La tupla original es: (5, 6, 7, 4, 9) 
Tupla convertida con K: [5, ‘Gfg’, 6, ‘Gfg’, 7, ‘Gfg’, 4, ‘Gfg’, 9, ‘Gfg ‘]

Método #2: Usar chain.from_iterable() + list() + generador de expresión

Esto es similar al método anterior, la diferencia es que el bucle anidado se evita aplanando usando chain.from_iterable().

# Python3 code to demonstrate working of
# Convert tuple to List with succeeding element
# Using chain.from_iterable() + list() + generator expression
from itertools import chain
 
# initializing tuple
test_tup = (5, 6, 7, 4, 9)
 
# printing original tuple
print("The original tuple is : ", test_tup)
 
# initializing K
K = "Gfg"
 
# list comprehension for nested loop for flatten
res = list(chain.from_iterable((ele, K) for ele in test_tup))
 
# printing result
print("Converted Tuple with K : ", res)

Producción:

La tupla original es: (5, 6, 7, 4, 9) 
Tupla convertida con K: [5, ‘Gfg’, 6, ‘Gfg’, 7, ‘Gfg’, 4, ‘Gfg’, 9, ‘Gfg ‘]

Método #3: Usando los métodos list(), map(), join(), split()

# Python3 code to demonstrate working of
# Convert tuple to List with succeeding element
 
# initializing tuple
test_tup = (5, 6, 7, 4, 9)
 
# printing original tuple
print("The original tuple is : ", test_tup)
 
# initializing K
K = "Gfg"
x = list(map(str, test_tup))
b = "*"+K+"*"
a = b.join(x)
c = a.split("*")
c.append(K)
res = []
for i in c:
    if(i != K):
        res.append(int(i))
    else:
        res.append(i)
# printing result
print("Converted Tuple with K : ", res)
