try block inside while statement

Question

I\'m just starting out with Python 2.7 and I don\'t understand why something is happening:

In the following code, an embellished version of an example from the pytho

Answer 1

The break statement is pulling out of the loop, so the else statement will never be reached.

Put the break in the else clause instead, like so:

while True:
    try:
        x = int(raw_input("Please enter a number: "))
    except ValueError:
        print "Oops!  That was not a valid number.  Try again..."
    else:
        print 'Thanks,',x,'is indeed an integer'
        break

print 'all done, bye'

Answer 2

i recently faced a question in which no input, for how many test cases .while loop and try-except are very helpful.

while(True):
    try:
        x=(input())
        x1,x2=x.split()
        print(int(x1)+int(x2))
    except:
        break

Answer 3

It is probably because of the break statement, which leaves the loop. The break statement is only reached when there is no exception in the line before.

Answer 4

Not a python guy, but how about this

while True:
    try:
        x = int(raw_input("Please enter a number: "))
        print 'Thanks,', x, 'is indeed an integer'
    except ValueError:
        print "Oops!  That was not a valid number. Try again..."
    finally:
        print 'all done, bye'
