what is the difference between [(a,b),(c,d)] and [[a,b],[c,d]] and how can I turn one into another in python?

Question

So my question is exactly defined in the title. That is, what is the difference between

 [(a,b),(c,d)]

and

 [[a,b],[c,d]]

and how I can turn one into another in Python.

This question is partly duplicate but the main part is how to turn one into another which in not duplicate.

Since, I cannot answer on a closed question, here is the answer to the second half of your question: A Simple list comprehension should suffice. `a = [(a,b),(c,d)]` `b = [list(x) for x in a]` `c = [[a,b],[c,d]]` `d = [tuple(x) for x in c]` — Tom Myddeltyn, Jul 01 '16 at 21:04

A list is that which encloses its contents in a bracket [].

A tuple is that which encloses its contents in a parentheses ().

Lists are mutable (changeable); tuples are not.

Turning a list into a tuple is possible:

Changing a tuple to list:

list(myTuple)

Changing list to tuple:

tuple(myList)

`list` function should do it – user25064 Jul 01 '16 at 21:00
Downvoted because this answer is much less comprehensive than those on the marked duplicate. – miradulo Jul 01 '16 at 21:00
@user25064 I've edited my answer. Did it help? – Jossie Calderon Jul 01 '16 at 21:01

You guys are very interesting. Look at the title of the question and it is obvious that I did not know even what to search for and this was my main problem. How should I even know that this question was duplicate without knowing the terms? – HimanAB Jul 01 '16 at 21:04
@HimanUCC A google search for "list to tuple and back" brings [this](http://stackoverflow.com/questions/16296643/convert-tuple-to-list-and-back). Did my answer resolve your question?

@jossie Calderon If I knew it was called "tuple", why should I even ask the question? – HimanAB Jul 01 '16 at 21:07
@HimanUCC By Google searching "the difference between brackets and parentheses in python". – Jossie Calderon Jul 01 '16 at 21:08
if the downvotes bother you @HimanUCC you can just remove your question. Hopefully the duplicate and the discussion helped you out. Also, try the python.org tutorial.. Lots of basic stuff there – joel goldstick Jul 01 '16 at 21:58
