Answer:

#Declare variable to get the input

#list from the user

input_list = input()

#split the list into words by space

list = input_list.split()

#Begin for-loop to iterate each word

#to get the word frequency

for word in list:

#get the frequency for each word

frequency=list.count(word)

#print word and frequency

print(word,frequency)

Explanation:

This program that we are told to write will be done by using python programming language/ High-level programming language.

The question wants us to write a program in which the output will be as below;

hey 1

hi 2

Write an application that displays every perfect number from 1 through 1,000. A perfect number is one that equals the sum of all

matrenka [14]

Answer:

Written in Python

for num in range(1,1001):

sum=0

for j in range(1,num+1):

if num%j==0:

sum = sum + j

if num == sum:

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

Explanation:

This line gets the range from 1 to 1000

for num in range(1,1001):

This line initializes sum to 0 for each number 1 to 1000

sum=0

This line gets the divisor for each number 1 to 1000

for j in range(1,num+1):

This following if condition line checks for divisor of each number

The following if condition checks for perfect number

if num == sum:

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