Python program to reverse a number

n = int(input("please give a number : "))

print("before reverse your numeber is : ",n)

reverse = 0

while n!=0:

    reverse = reverse*10 + n%10       

    n = (n//10)

print("After reverse : %d" %reverse) 

Python program for palindrome using an iterative method

n=int(input("Enter a number: "))

reverse,temp=0,n

while temp!=0:

    reverse=reverse*10+temp%10

    temp=temp//10

if reverse==n:

    print("number is palindrom")

else:

    print("number is not palindrom")

Program to check a number is Armstrong or not in

num = int(input("please give a number : "))

if num!=0:

    input_number=[]

    res = [int(x) for x in str(num)]

    print(res)

    for i in res:

        input_number.append(i**3)

        result = 0

        for ele in range(0, len(input_number)):

            result = result + input_number[ele]

    if num==result:

        print("number is armstrong")

    else:

        print("number is not armstrong") 

            

    

else:

    print("Please enter a Number > 1")

check given number is prime or not

num = int(input("please give a number : "))

# define a flag variable

flag = False

# prime numbers are greater than 1

if num > 1:

    # check for factors

    for i in range(2, num):

        if (num % i) == 0:

            # if factor is found, set flag to True

            flag = True

            # break out of loop

            break

# check if flag is True

if flag:

    print(num, "is not a prime number")

else:

    print(num, "is a prime number")

Fibonacci series program in python using iterative method

first,second=0,1

n = int(input("please give a number for fibonacci series : "))

print("fibonacci series are : ")

for i in range(0,n):

    if i<=1:

        result=i

    else:

      result = first + second;

      first = second;

      second = result;

    print(result)
