Errors detected during execution of program are called exceptions. Exceptions can be handled using the try..except statement. We basically put our usual statements within the try-block and put all our error handlers in the except-block.

try…except demo code:

>>> while True:

try:

x = int(raw_input("Enter no. of your choice: "))

break

except ValueError:

print "Oops! Not a valid number. Attempt again"

Enter no. of your choice: 12ww

Oops! Not a valid number. Attempt again

Enter no. of your choice: hi there

Oops! Not a valid number. Attempt again

Enter no. of your choice: 22
