If you enter 1.23 you've just tested the except branch:

>>> while True:
...     try:
...         x = int(raw_input("Please enter a number: "))
...         break
...     except ValueError:
...         print "Oops!  That was no valid number.  Try again..."
...
Please enter a number: 1.23
Oops!  That was no valid number.  Try again...
Please enter a number:


As far as I can see, the example works as expected, and there's
nothing wrong with it (not even the imprecise indication of what
number to enter).

Cheers,
