Answer:

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.

ddd [48]

<u>Answer:</u>

<em>FUNCTION:</em>

  • A function does not require the number of times that the <em>code script needs to be executed </em>
  • When we go for large programming, ie. while creating projects, we can invoke function from one file to another based on the access <em>specifier mentioned for the function. </em>
  • There is a stack call created in the memory whenever a <em>function is called. </em>

<em>LOOP :</em>

  • Whereas the number of times that the loop has to be <em>executed must be defined </em>
  • A loop cannot be called, it can be used only the code block in <em>which it is present. </em>
  • There is not overhead of creating a stack since it is not invoked and there is no <em>transfer of control from one module to another </em>
