For educational purposes (i.e. hooking easily into graphics packages for visualization) you can make a linked list in Python, using elements like: class Node: def __init__(self, dataval=None): self.dataval = dataval self.nodepointer = None The only reason to do this is for education/visualization of data structures, although I'm wondering if this can be engineered to cause a Python memory leak, via circularization of the linked list, or if Python's GC would catch it. Also educational perhaps. Where linked lists really seem to come into play is with custom manual memory allocators in embedded programming, something of a niche subject.
