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

You mean that you want something like:

''.join(n for n in phone_str if n.isdigit())

This uses the fact that strings are iterable. They yield 1 character at a time when you iterate over them.

Regarding your efforts,

This one actually removes all of the digits from the string leaving you with only non-digits.

x = row.translate(None, string.digits)

This one splits the string on runs of whitespace, not after each character:

list = x.split()
