I don't know what is wrong with this.HELP (PYTHON---TRY AND EXCEPT)

I was just testing my new skills of try and except,but then i came face to face with a TypeError it sayed "TypeError: Can't multiply sequence by non-int by type 'str' " I should get the message "that's not a number" but insted i get a TypeError this means that except block of code is not working the code that I enter is

try:

      a = input('give me a number:  ')

except TypeError:

       print('that's not a number')

else:

       print("hi"*a)

input converts every input to a string. It does not matter if you enter a number or a word it gets converted to an string. You can not multiply a string with a string.

I dont see the use of TypeError here it does not prefent the input of words.

Here is what you need:

userInput = input('give me a number:  ')
try:
// try to convert a varaible to an int
   val = int(userInput)
// if it fails throw a exception
except ValueError:
   print("That's not an int!")
