import re

chars = '123#@hello#a111'
new = []
while len(chars) > 0:
    if chars[0].isdigit():
        res = re.match(r'\d+', chars).group()
        n = len(res)
        new.append(res)
        chars = chars[n:]
    elif chars[0].isalpha():
        res = re.match(r'[a-zA-Z]+', chars).group()
        n = len(res)
        new.append(res)
        chars = chars[n:]
    else:
        res = re.match(r'[^a-zA-Z0-9]+', chars).group()
        n = len(res)
        new.append(res)
        chars = chars[n:]

print(new)
