i = 1

while i < 10001:

   total = 0

   x = 1

   while x < i:

       if i % x == 0:

           total += x

       x+=1

   if total == i:

       print(str(i)+" is a perfect number")

   i += 1

When you run this code, you'll see that 6, 28, 496, and 8128 are all perfect numbers.

Elden [556K]

Answer:

Parent

Explanation:

HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.

Generally, all HTML documents are divided into two (2) main parts; body and head. The head contains information such as version of HTML, title of a page, metadata, link to custom favicons and CSS etc. The body of a HTML document contains the contents or informations that a web page displays.

In this scenario, Roger wants to give semantic meaning (an element conveying informations about the type of content contained within an opening and closing tag) to a contact information placed at the bottom of a webpage. Thus, in order to do this, he should use a footer element as a parent of the contact information and as such all instance variables that have been used or declared in the footer class (superclass) would be present in its contact information (subclass object).
