Tree Traversal

🎯 Output all nodes in a tree.

Collect all living beings from the following tree structure in a single list.

tree3 = [
          ['Rose', 'banana tree'],
          [
            [
              ['hammerhead shark', 'stingray'],
              [
                ['chimp', 'human'],
                 'rat'
              ]
            ],
            ['bee', 'ant']
          ]
        ]

Hint

Hints:

• Draw the tree. In which order would you go through the beings?

• How can you check whether you are dealing with a string or a list?

• Is it basically possible to walk trees of any depth with the same program?

• Research “Tree Traversal”
