while a<=n:
    print(a)
    a,b=b,a+b

23.1.2. Write a python program to print prime numbers in a range

#write your code here
x = int(input("x: "))
y = int(input("y: "))
p = ""
for i in range(x,y):
    if(i > 1):
        for j in range(2,i):
            if (i%j)==0:
                break
        else:
            print(i)

23.1.3. Write a python program to find if a number is armstrong or not

#write your code here
n = input("n: ")
r = len(n)
n = int(n)
s = 0
t = n
while t>0:
    d = t%10
    s += d**r

print("sum of powers:", s)
if s == n:
    print("armstrong number")
else:
    print("not armstrong number")

23.1.4. Program to find a character is a vowel or consonant

# Type your program here...

    d=n%10
    while (i<=d):
        f *= i
        i += 1
    s += f
    n //= 10
if (s == t):
    print("strong number")
else:
    print("not a strong number")

23.1.7. Write a Python program to find the Biggest of Three numbers using nested if-else-if

#write your logic here
a,b,c = [int(x) for x in input("a,b,c: ").split(",")]
g=0
for i in a,b,c:
    if g<i:
        g=i
print(g)

    for j in range(1, i+1):
        print(num, end=" ")
        num +=1
    print()

23.1.9. Program to determine if a number is perfect number and abundant number and deficient number

num = int(input("num: "))
list1=[]
s = 0
for i in range(1,num):
    if(num%i==0):
        list1.append(i)
print("factors:", list1)
for i in list1:
    s += i
print("sum:", s)
if(s==num):
    print("perfect")
elif(s>num):
    print("abundant")
else:
    print("deficient")

for i in range(1,rows+1):
    print(" "*(rows-i),end=" ")
    c=1
    for j in range(1,i+1):
        print(c, sep="", end=" ")
        c=c*(i-j)//j
    print()

23.1.11. Program to determine if a number is prime

num = int(input("num: "))
p=0
for i in range(2,num):
    if(num%i == 0):
        p = "not a prime number"
        break
    else:
        p = "prime number"
print(p)
