robust_input

Language/Type: Python input

The following code is not robust against invalid user input. Change the code so that it will not proceed until the user has entered a valid age (any integer) and grade point average (GPA, any real number). You may assume that the user enters a single token of input each time when prompted. Here is a sample dialogue of how the code should behave: 

Type your age: hello
Type your age: ?
Type your age: 3.14
Type your age: 25
Type your GPA: a
Type your GPA: bcd
Type your GPA: 2.5
age = 25  GPA = 2.5
Bare code: Write a fragment of Python code as described, without any class or function/method heading around your code.
