break up a value in a list to a list of individual items

[r3bol]

Hi, sorry to post this, but I've had a really hard time finding how to
do it.
Q.
How can I break up a value in a list to a list of individual items
(preferably without importing any modules)?
Like...
['12345'] (string)
to
[1, 2, 3, 4, 5] [numbers]

Thanks.

[int(i) for i in ['12345'][0]]

nums = [int(char) for char in '12345']

Note also that:
list("1234") == ["1", "2", "3", "4"]

And do be sure to read one of the several fine Python tutorials.

Cheers,
Chris

Here's one way:

>>map(int, '12345')

[1, 2, 3, 4, 5]

You did not specify what you want to happen if the original list has
more than one item. If you want to keep the other items....

>>lst = [1, '234', 5]
>>lst[1:2] = [int(i) for i in lst[1]] # insert slice
>>lst

[1, 2, 3, 4, 5]

>>lst = [1, '234', 5]
>>lst[1] = [int(i) for i in lst[1]] # insert item
>>lst

[1, [2, 3, 4], 5]
