Answer:
The program written in Python is as follows:
<em>See Explanation section for line by line explanation</em>
for n in range(100,1000):
isum = 0
for d in range(1,n):
if n%d == 0:
isum += d
if isum == n * 2:
print(n)
Explanation:
The program only considers 3 digit numbers. hence the range of n is from 100 to 999
for n in range(100,1000):
This line initializes sum to 0
isum = 0
This line is an iteration that stands as the divisor
for d in range(1,n):
This line checks if a number, d can evenly divide n
if n%d == 0:
If yes, the sum is updated
isum += d
This line checks if the current number n is a double-perfect number
if isum == n * 2:
If yes, n is printed
print(n)
<em>When the program is run, the displayed output is 120 and 672</em>
Answer:
shortNames = ['Gus', 'Bob','Zoe']
Explanation:
In this assignment, your knowledge of list is been tested. A list is data structure type in python that can hold different elements (items) of different type. The general syntax of a list is
listName = [item1, "item2", item3]
listName refers to the name of the list variable, this is followed by a pair of square brackets, inside the square brackets we have items separated by commas. This is a declaration and initialization of a list with some elements.
The complete python code snippet for this assignment is given below:
<em>shortNames = ['Gus', 'Bob','Zoe']</em>
<em>print(shortNames[0])</em>
<em>print(shortNames[1])</em>
<em>print(shortNames[2])</em>
