Hi, I am new in Python. I have already red about "_" and about groupby() from itertools but don't understand how it works, can you give description about your solution please? As I understand, you create list g and use groupby() function with key = "last value" (_) and each element from list g in list els ? It looks like you compare each element in g and els, but how do you compare the previous value? and what is list g?

Nice solution! Good use of groupby Class from module itertools into a list comprehension!
