import tree, sys
print("tree.branch: 'root' in dir(tree) ->", 'root' in dir(tree))
print("tree.branch: 'tree.root' in sys.modules ->", 'tree.root' in
sys.modules)

Ignore this part - my fault. It should have been:

import sys
print("tree.branch: 'root' in dir(main) ->", 'root' in
dir(sys.modules['__main__']))
print("tree.branch: 'tree.root' in sys.modules ->", 'tree.root' in
sys.modules)

This shows that `root` attribute does not exist yet in main, though
'tree.root' exists in `sys.modules`.
