I keep receiving traceback calls and other errors (not syntax) when I try to come up with a function for this practice question. An answer that I can compare my attempts to would be very helpful.

Here is the question:

A run is a sequence of consecutive repeated values. Implement a Python function called two_length_run that takes a list of numbers as input and returns True if the given list has is at least one run (of length at least two), and False otherwise. Make sure the function is efficient (i.e. it stops as soon as the answer is known). Then, in the main, your program should ask the user to input the list, then it should call two_length_run function, and print the result. You may assume that the user will always enter at least two elements, but your function two_length_run should work for all lists of numbers including those of length 0 and 1
