x.push('www.sololearn.com/courses/JUMP_LINK__&&__python__&&__JUMP_LINK/')

while not x.is_empty():
print(x.pop())

Answer 1

An instance of the Browser is created (x), links are added. In the while loop, links are removed until it is empty.

Answer 2

Lisa I thought that if there was an empty link, the loop would delete it and not that it was all deleted until it was empty

Answer 3

What is an empty link?

Try to run this code and see what is being removed.
