Answer / chaitanya
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
