Find the number of Python uppercase, lowercase, and special characters

>>> uppercase = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
>>> Lowercase = "abcdefghijklmnopqrstuvwxyz"
>>> Number = "0123456789"
>>> s = "p0Y123!@#THon"
>>> s_u, s_l, s_n, s_s = "", "", "", ""
>>> for c in s:
    If c in uppercase:
        s_u += c
    elifc in lower case:
        s_l += c
    elif c in number:
        s_n += c
    else:
        s_s += c


>>> s_u, s_l, s_n, s_s
('YTH', 'pon', '0123', '!@#')
>>> len(s_u), len(s_l), len(s_n), len(s_s)
(3, 3, 4, 3)

>>> s = 'p0Y123!@#THon'
>>> import string
>>> string.digits
'0123456789'
>>> string.ascii_lowercase
'abcdefghijklmnopqrstuvwxyz'
>>> string.ascii_uppercase
'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
>>> list(filter(lambda c:c in string.ascii_lowercase, s))
['p', 'o', 'n']
