output of following code??explain briefly please

Question

d = {'foo': 1, 'bar': 2, 'baz': 3}
while d:
print(d.popitem())
print('Done.')

Answer 1

While d:
it denotes the values in the d.
Which means until d becomes false perform following..

d.popitem()
It is a function that performs pop operation.
Pop operation is removing the last item.(for more info learn abt stack). as it is in while loop it removes the items in the d continuously until it becomes null.

Aftering removing all items in d , it exits from while loop and then follows the print statement (done..)

Hope u understood..
