 +====== Accessing Events in a Tree ======
 +To access the events in a tree no variables need to be assigned to the different branches. ​
 +Instead the leaves are available as properties of the tree, returning the values of the present event.
 +<code python>
 +print tree.Z0_MM ​ # 18558.9
 +print tree.Z0_MM ​ # 2896.5
 +To iterate over all events, a ''​for''​ loop can be used directly on the tree object
 +<code python>
 +for event in tree:
 +    print event.Z0_MM
