How to add each number to list in python?

Question

I have following variable:

number = "456367"

I need to add it to list by one number, like this:

list = [['4', '5', '6', '3', '6', '7']]

How can I achieve this?

Do you really want a [['4', '5', '6', '3', '6', '7']] as your return value, as opposed to a ['4', '5', '6', '3', '6', '7']? — donkopotamus

Since a string is iterable, pass it to the list constructor:

>>> list("456367")
['4', '5', '6', '3', '6', '7']

Which is why you would not want to name the result list because you would stomp on the name of that convenient function ;-)

If you really want [['4', '5', '6', '3', '6', '7']] vs just a list of characters:

>>> s="456367"
>>> map(list, zip(*s))
[['4', '5', '6', '3', '6', '7']]

Or,

>>> [list(s)]
[['4', '5', '6', '3', '6', '7']]

But I am assuming with the first answer that the extra brackets were a typo.

>>> number = "456367"
>>> [char for char in number]
['4', '5', '6', '3', '6', '7']
