Good question! You can try the following code for this. =)

This code uses ast.literal_eval() to find the data type of the input (age). Then it follows the following algorithm:

1. Ask user to input her/his age.

1.1. If age is float or int data type:

 - Check if `age>18`. If `age>18`, print appropriate output and exit. 

 - Check if `0<age<=18`. If `0<age<=18`, print appropriate output and exit. 

 - If `age<=0`, ask the user to input a valid number for age again, (*i.e.* go back to step 1.) 

1.2. If age is not float or int data type, then ask user to input her/his age again (i.e. go back to step 1.)

Here is the code.

from ast import literal_eval ''' This function is used to identify the data type of input data.''' def input_type(input_data): try: return type(literal_eval(input_data)) except (ValueError, SyntaxError): return str flag = True while(flag): age = raw_input("Please enter your age: ") if input_type(age)==float or input_type(age)==int: if eval(age)>18: print("You are able to vote in the United States!") flag = False elif eval(age)>0 and eval(age)<=18: print("You are not able to vote in the United States.") flag = False else: print("Please enter a valid number as your age.") else: print("Sorry, I didn't understand that.")

• If age is float or int data type:

  - Check if `age>18`. If `age>18`, print appropriate output and exit. - Check if `0<age<=18`. If `0<age<=18`, print appropriate output and exit. - If `age<=0`, ask the user to input a valid number for age again. 

• If age is not float or int data type, then ask user to input her/his age again.
