Convert string (without any separator) to list

Question

I have a phone number(string), e.g. \"+123-456-7890\", that I want to turn into a list that looks like: [+, 1, 2, 3, -, ...., 0].

Why? So I can go iterate through t

Answer 1

Instead of converting to a list, you could just iterate over the first string and create a second string by adding each of the digit characters you find to that new string.

Answer 2

Make a list(your_string).

>>> s = "mep"
>>> list(s)
['m', 'e', 'p']

Answer 3

A python string is a list of characters. You can iterate over it right now!

justdigits = ""
for char in string:
    if char.isdigit():
        justdigits += str(char)
