Is there a succinct way to split this negative integer into a list of digits? (Python)

Question

I can do this using an if statement but I feel like the code is too long for this simple operation.

num = -12345

-->inserts magical code<--

desired output

num_list = ['-1', '2', '3', '4', '5']

I have been coding for 20 years, I did need to convert a number into a string hundreds of time. I did need to convert a string into an array of characters hundreds of time. I never needed to convert into an array of characters where the fist character would also contain the sign. it is not a common operation at all. So I doubt you'll fine a library for this. You'll have to write your "if" !! What language is it? — Pascal Ganaye, Jul 26 '20 at 22:01

You can simply use .split("\\B")

So the magical code would be:

String[] num_list = Integer.toString(num).split("\\B");

NameError: name 'Integer' is not defined, is Integer an imported function? – Adam Zawitkowski Jul 26 '20 at 20:32
@AdamZawitkowski I've answered in Java... "\\B" is a regular expression, you can check how to do the same in Python... – Juliano Costa Jul 27 '20 at 06:10
