Python
def is_int_or_float(s):
    try:
        float(s)
    except (TypeError, ValueError):
        return False
    else:
        return True

Test return value of is_int_or_float, isdigit, and isdecimal.

Python
char_list = (
    [None, '', '0', '0.0', '0.1', '0.123456789', '1.0'] +
    [
      chr(number) for number in itertools.chain(
        range(1000),
        range(4969, 4978),
        range(8304, 11000),
      )
    ])
 
line = '-' * 55
checkmark = '\u2713'
print(line)
print('| char        | is_int_or_float | isdigit | isdecimal |')
print(line)
for char in char_list:
    char_is_int_or_float = is_int_or_float(char)
    try:
        char_isdigit = char.isdigit()
    except AttributeError:
        char_isdigit = False
    try:
        char_isdecimal = char.isdecimal()
    except AttributeError:
        char_isdecimal = False
    if char_is_int_or_float or char_isdigit or char_isdecimal:
        print('| {0:>11} | {1:^15} | {2:^7} | {3:^9} |'.format(
            char,
            checkmark if char_is_int_or_float else '',
            checkmark if char_isdigit else '',
            checkmark if char_isdecimal else '',
