GIVEN NUMBER IS A FIBONACCI NUMBER¶

In [8]:
num=int(input("Enter the number"))
temp=1
k=0
a=0
sum=0
while sum<=num:
    sum=temp+k
    temp=sum
    k=temp
    if sum==num:
        a=a+1
        print("Yes. {} is a fibonnaci number".format(num))
        break
if a==0:
    print("No. {} is NOT a fibonacci number".format(num))

Enter the number2
Yes. 2 is a fibonnaci number

PROGRAM TO CHECK ARMSTRONG NUMBER¶

In [11]:
num = int(input("enter a number:"))
t = num
cube_sum = 0
while t!=0:
    k=t%10
    cube_sum+=k**3
    t=t//10
if cube_sum==num:
    print(num,"is an armstrong number")
else:
    print(num,"is not a armstrong number")

enter a number:153
153 is an armstrong number
