Just try converting them: float_list = [] for s in string_list: try: float_list.append(float(s)) except ValueError: # ignore bad strings pass do_something_with_floats(float_list) > s1.isdigit returns False. "2" is a digit. "23" is two digits. You want something like s1.isfloat(), but why bother checking first?
