Python While Loop Tutorial #Day3

Tasks on While Loop:

1. Armstrong Number 351 3*3*3 5*5*5 1*1*1 27 125 1 153 -> not a Armstrong number
2. Neon Number A neon number is a number where the sum of digits of square of the number is equal to the number. 9 --> 81 --> 8 1 = 9 is a Neon Number
3. Factorial of a Number 4 = 4! = 4*3*2*1 = 24
4. Perfect Number Sum of Divisors of a Number(except the num itself) returns the same number -> Perfect number 6 - 1, 2, 3 -> 1 2 3 = 6
5. Prime Number
6. List of Prime Number
7. Emirp Number

#Armstrong

def Armstrong(count, Num):
    sum = 0
    i=0
    Out = Num
    while i<count: sum="sum" num="Num//10" i if out print else: a armstrong the num: count="0" while>=1:
    Num = Num//10
    count+=1
print('count :',count,' ')
Armstrong(count, out)


#Neon Number

Num = int(input("Enter the num:"))
Square = Num*Num
Neon = Num
Sum = 0
print(Square)
while Square >=1:
        Sum = Sum + (Square%10)
        Square = Square//10
if(Sum == Num):    
    print(Num,'Neon Number')
else:
    print(Num,'Not a Neon Number')



# Factorial of a Number

Num = int(input('Enter the Num:'))
Fact = 1
while Num>=1:
    Fact = Fact * Num
    Num = Num-1
print('Factorial:', Fact)

#Perfect Number

Num = int(input('Enter the number:'))
i = 1
sum = 0
while i<num: if sum="sum" i num print a perfect number else: not the num: prime="1">1:
    while i<num: if prime="0" i print a number else: not valid num of numbers the num: j="2">1:
    while j 1:
        while i<num: if prime="0" i return num="int(input('Enter" the num: isprime="isPrimeNumber(Num)" rev_num="0" rev="Num" while>=1:

            Num = Num//10
    print(rev_Num)

    if(isPrime ==1):
        print(rev,'is a Emirp Number')
    else:
        print(rev,'is not a Emirp Number')
else:
    print(Num,'is not a Emirp Number')
