Cordial greeting.
I have a list with str inside it in the following way:
l1=['hola estas','como Carol','esta tu ','aqui papa ']
and I want something like this to stay:
l2=['hola-como', 'estas-Carol','esta-aqui', 'tu-papa']
Each str of the list l1 has the same length and each word is separated for the same spaces.
Thank you for your attention.
I'm not sure how you expect to combine the words of each element str . Suppose you want to combine in pairs, two by two:
l1=['hola estas','como Carol','esta tu ','aqui papa ']
palabras = [s.split() for s in l1]
l2 = [ x+"-"+y for i in range(0,len(l1),2)
for (x,y) in zip(palabras[i],palabras[i+1]) ]
As I put you in a comment, the code does what you ask. It serves for any number of elements and any number of words per element. But you will say if it is what you were looking for.
This is a way to achieve what you want for any number of elements:
l1 = ['hola estas','como Carol','esta tu ','aqui papa ']
#Creamos un array donde almacenamos el resultado.
l2 = []
#Dos arrays para almacenar textos de la izquierda y derecha de cada elemento el arreglo original.
aLeft = []
aRight = []
#Agrega los textos a su correspondiente arreglo, aLeft para textos izquierda, aRight para textos derecha.
for i in l1:
aLeft.append(i.split()[0])
aRight.append(i.split()[1])
for i in range(0, len(aLeft), 2):
l2.append(aLeft[i] + "-" + aLeft[i+1])
l2.append(aRight[i] + "-" + aRight[i+1])
print l2
with a result:
['hola-como', 'estas-Carol', 'esta-aqui', 'tu-papa']
