running code if try statements were successful in python

You are looking for the else keyword:

try:
    #code that might fail
except SomeException:
    #error handling if code failed
else:
    # do this if no exception occured

You want else:

for i in [0, 1]:
    try:
        print '10 / %i: ' % i, 10 / i
    except:
        print 'Uh-Oh'
    else:
        print 'Yay!'
