Given a list of elements, create and return a list whose elements are lists that contain the consecutive runs of equal elements of the original list. This particular problem is also common when we need to accumulate the minimum and store consecutive group minimum. But a useful variation of this can also be a case in which we need to consider a tolerance level, i.e allowing a skip value between number and not being exactly consecutive but a “gap” is allowed between numbers. Each element in the resulting iterator is a tuple, where the first element ([code ]group[/code] in my example) is the "key", which is a label for that group. Consecutive runs of equal elements. You can also use the built-in numpy.grad. 1-3,6-7,10 This seemed like a nice example of how the dictionary data type can be used in Python. Speed comparison.
