How to split an element in a list? - Python 3

Question

If I had a list that looked like:
list1 = [‘A dog, a cat’, ‘a mouse, a rabbit’]

How would I iterate through the list so I could split it using .split(‘,’)
I would want the outcome to look like: list1 = [‘a dog’, ‘a cat’, ‘a mouse’, ‘a rabbit’]

So that they are seperate elements rather than a joint string if that makes sense?

Answer 1

list1 = ["A dog, a cat", "a mouse, a rabbit"]
b=[]
for i in list1:
b+=i.split(",")
print(b)

Answer 2

I would prefer the version from HonFu, but i was to late. So for the reason of showing different approaches, here is a version using a comprehension:

out1 = []
[out1.extend(i.split(', ')) for i in list1]
print(out1)

Answer 3

You could make a new list, iterate through the list and append all items to the new list with the help of the split method.

Answer 4

Following Seb TheS's algorithm,

list1 = ['A dog, a cat', 'a mouse, a rabbit', 'a horse']
separator, list2 = ', ', []
for e in list1:
if separator in e:
list2.extend(e.split(separator))
else:
list2.append(e)
print(list2)

Answer 5

list2 = ', '.join(list1).split(', ')

list1 = ['A dog, a cat', 'a mouse, a rabbit']
list1 = ', '.join(list1).split(', ')
print(list1)

It's exactly what Luna wanted to get as a result.

Answer 7

Personally: join it into a single string, and then split it into a list.

list1 = ['A dog, a cat', 'a mouse, a rabbit']
list1 = ', '.join(list1).split(', ')
print(list1) # ['A dog', 'a cat', 'a mouse', 'a rabbit']

Edit: I realised that didn't quite answer your question in the way you asked it, but I'll leave it up to demonstrate another possible way of doing it.

Answer 8

HonFu I think your answer was not relevant to the question.

Answer 9

By simply using split function or you can google it
