Write a method doubleUp that doubles the size of a list of integers by doubling-up each element in the list. Assume there's enough space in the array to double the size. Suppose a list stores the values [1, 3, 2, 7]. After calling list. doubleUp(), the list should store the values [1, 1, 3, 3, 2, 2, 7, 7].

def double_up(self, mylist):

   doubled = list()

   for item in mylist:

       for i in range(2):

           doubled.append(item)

   return doubled

Explanation:

The program method double_up gets the list argument, iterates over the list and double of each item is appended to a new list called doubled.

Methods are functions defined in classes. A class is a blueprint of a data structure. Each instance of the same class holds the same attributes and features.

answer; i believe that the correct answer is (department   of highway safety and motor vehicles);

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
