Question

Hi I want to loop my program so that as soon as it hits Exceptions it restarts from the beginning !

>>> while True:
...     try:
...         x = int(raw_input("Please enter a number: "))
...         break
...     except ValueError:
...         print "Oops!  That was no valid number.  Try again..."

How can I do this

You want to remove the break in your try statement. It’s telling python to exit the while loop.

    try:
        x = int(raw_input("Please enter a number: "))
    except ValueError:
        print "Oops! That was no valid number. Try again..."
