the input is [120, [10, 20, 30]]
i split the balance using this code

``````def checkio(data):
balance=[int(x) for x in data[0:1]]
withdrawal=data[1:2]
``````

but when i split it the withdrawal section looks like [[10,20,30]]
which hinders the loops im going to do.
I want it to have single brackets like so: [10,20,30]
how do i go about doing this

`data[1:2]` is a list splice. It returns the sublist of `data` that goes from index 1 (inclusive) to index 2 (exclusive). So basically it returns a list that contains the element at index 1 and nothing else. If all you want is the element at index 1 without a list wrapped around it, just use normal indexing:

``````withdrawal = data[1]
``````

It also seems strange to me that you use a list comprehension on a 1-element list to get the balance. I would just do `balance = int(data[0])` if I were you. If there's a good reason why balance should be a 1-element list, you could also do `balance = [ int(data[0]) ]`, but I don't see what that reason could be.

The list show only integer,so why convert at all.

``````>>> lst = [120, [10, 20, 30]]
>>> lst[0]
120
>>> lst[1]
[10, 20, 30]
>>> type(lst[0])
<type 'int'>

>>> balance, withdrawal = lst[0], lst[1]
>>> balance
120
>>> withdrawal
[10, 20, 30]
``````

`data[1:2][0]` first entry of your result

data[1:2][0]

Why would one possibly write that rather than `data[1]`?

Thanks everyone!
It was so simple i cant beleive i overlooked it!
