Answer:
// program in Python to check perfect number
#function to find number is perfect or not
def is_Perfect_Number(n):
#total variable
tot = 1
i = 2
#sum of all divisor of number
while i*i<=n:
if n%i==0:
tot = tot + i + n/i
if tot == n and n != 1:
return 1
i = i+1
return 0
#read until user enter a perfect number
while True:
#read integer
num = int(input("Input an integer: "))
#call the function
if(is_Perfect_Number(num)):
print(num,"is perfect number")
#if perfect number break
break
else:
print(num,"is not a perfect number")
#ask again
print("try again.")
Explanation:
Read number from user and then call the function is_Perfect_Number() with parameter "num".This will find the sum of all divisor of number.If sum is equal to number then it will return 1 else return 0.If the number is not perfect then it will again ask to enter a number until user enter a perfect number.
Output:
Input an integer: 24
24 is not a perfect number
try again.
Input an integer: 28
28 is perfect number

False.
The different between break and continue instruction is that with break you exit the loop, and with continue you skip to the next iteration.
So, for example, a loop like
for(i = 1; i <= 10; i++){
if(i <= 5){
print(i);
} else {
break;
}
}
will print 1,2,3,4,5, because when i=6 you will enter the else branch and you will exit the loop because of the break instruction.
On the other hand, a loop like
for(i = 1; i <= 10; i++){
if(i % 2 == 0){
print(i);
} else {
continue;
}
}
Will print 2,4,6,8,10, because if i is even you print it, and if i is odd you will simply skip to the next iteration.
