Nested lists

Question

How can I print lists within a list? Using for loop, it only prints out the outer list arranged vertically while the inner list remain the way it is. How can I make everything come out vertically? This is for Python.

Answer 1

Recursive approach:

It will be slower for bigger lists tho

Answer 2

Mbrustler that's what recursive functions are for, you do something recursively rather than doing it by hand.
So here, you'd call the function again if the type of an element is a list. It works for lists of any dimension.

Answer 3

HonFu thanx! <3
Mbrustler yes true! It would help to understand what a recursive function is actually doing.

Answer 4

i still dont understand what you exactly mean do you want something like this ?

Answer 5

okay thanks a lot.

Answer 6

i know but writing it helps for under standing the basic structure
i would menton but dont know how to XD

Answer 7

Yash Kandalkar, you rocked this. :)

Answer 8

can you give an example?

do you mean like
a = [[1,2],[3,4]]
and you want
1234 as output or [1,2],[3,4]?

Answer 9

Let's say I have this:

Closefriends = ["andy", "valerie", "hector", "christina"["damien", "kimm"["lowry","donald"]]]

Now when I printed, andy, valerie, hector and Christina printed like this:
andy
valerie
hector
christina.

the rest stayed as nested list and still had the square brackets.

Answer 10

and you want to print without the lists?

Answer 11

I want to print the nested list the same way I printed the first four lists.

Answer 12

Yeah, something like this, but with kimm, lowry and donald arranged vertically just as valerie , hector, christina, and damien are arranged.

Answer 13

l = [1, 2, [3, 4], 5, 6]
for el in l:
if type(el) == list:
print(*el, end=' ')
else:
print(el, end=' ')

One way would be this.

If even the embedded lists contain lists, that won't work obviously.

Answer 14

well i will try some more but thats how much i can do for now code has been updated

Answer 15

#Let's say I have this:

Closefriends = ["andy", "valerie", "hector", "christina",["damien", "kimm",["lowry","donald"]]]

for x,y in enumerate(Closefriends):
if type(y) == list:
for k in y:
if type(k) == list:
for s in k:
print(s)
else:
print(k)
else:
print(y)

this is another way but it works just for nested lists of 3rd grade
