Creating an Array based on Definition/Points

Question

I'm currently new to python and working on a Class Project trying to create multiple polylines based on the tracking of Rhinos. I have the approach right, but I somehow have the variables switched around. The Rhino would be the key value, and the points would have to be added into it. The example would be "Rhino : {(Point 1),(Point 2)}". Somehow I can't get it. I can get the polyline to form, but I only get one giant line and not a multiple set of polylines based on the Rhino. Here is the script I have written down.(re-edited to just the definition of the function) def rhinoTracker(Rhino, X, Y, dictionary): XYCoord = (X, Y) if Rhino not in dictionary: dictionary[Rhino]= [] dictionary[Rhino].append((XYCoord))‍‍‍‍‍‍‍‍

On top of the other issues people have pointed out, what exactly do you want the output to look like?  Do you want a single, multi-part line, multiple single-part lines, or multiple multi-part lines?  And, what criteria is used to break up the features and lines into different parts.

You should be aiming for something like this: { 'Rhino1': [(X1, Y1), (X2, Y2), ...], 'Rhino2': [(X1, Y1), (X2, Y2), ...], ... }‍‍‍‍‍‍‍‍‍

With the definition at least, would there need to be a variable that needs to changed around so I could have the results change to "Rhino : {(Point 1),(Point 2)}" instead of {Rhino : [(Point 1),(Point 2)]}? That been my biggest problem so far.
