Use the `str.count()` method to check if a character appears twice in a string, e.g. `if my_str.count(char) == 2:`.
def parse_input(): string = raw_input() return string def check_string(string): check_funs = [str.isalnum, str.isalpha, str.isdigit, str.islower, str.isupper, ] return [any(fun(char) for char in string) for fun in check_funs] def print_output(results): for el in results...
