The integer sequence beginning with a single digit in which the next term is obtained by describing the previous term. In each step of the "count-and-say sequence" (which is more usually called the "look-and-say sequence") you have to find the groups of consecutive runs of identical digits.So if you have the value 111221, these groups are 111, 22, and 1.Python has a built-in function itertools.groupby for finding groups in an iterator, and using this function, the look-and-say step becomes: The look and say sequence is a basic form of run length encoding.
