I have a basic program that I am trying to make fool proof, and not come up with an error when the wrong type of data is entered.

Here is my code (Python 2)

   choice = raw_input("Enter a number")
   choice = int(choice)
   print choice + 1

However, when I enter a letter, it tries to convert it into a integer and fails. What would be the best way to overcome this?

What do you want it to do when you enter a letter? – Itay Sep 25 '16 at 08:52
You need to put that in `while` and `try|except`. `while` would run until user enter integer value, `try|except` would try to convert input to `int` – vishes_shell Sep 25 '16 at 08:53
Try the ```isdigit()``` function => https://docs.python.org/2/library/stdtypes.html#str.isdigit – kkaosninja Sep 25 '16 at 08:58
