1. Write a Python program to check if the given number is a Disarium Number? sol: def task1(num):

   try: if type(num) != int: raise Exception("Not an integer")

    num = str(num)
    total = 0
    for i in range(0, len(num)):
        n = int(num[i])
        n = n**(i+1)
        total = total + n
   
    if total == int(num):
        return True
    else:
        return False
   

   except Exception as e: print(e)

task1(147) False task1(135) True

2. Write a Python program to print all disarium numbers between 1 to 100? sol: for i in range(1, 101): if task1(i) == True: print(i, end = ' ') 1 2 3 4 5 6 7 8 9 89

3. Write a Python program to check if the given number is Happy Number? sol: def task3(num):

   res = num; def isHappy(num):
   r = 0;
   s = 0 while(num > 0):
   r = num%10
   s += r**2
   num //= 10
   return s

   while(res != 1 and res != 4):
   res = isHappy(res)

   if(res == 1):
   return True elif(res == 4):
   return False task3(100) True task3(4) False

4. Write a Python program to print all happy numbers between 1 and 100? sol: for i in range(1, 101): if task3(i) == True: print(i, end = ' ') 1 7 10 13 19 23 28 31 32 44 49 68 70 79 82 86 91 94 97 100

5. Write a Python program to determine whether the given number is a Harshad Number? sol: def task5(num): temp = num total = 0 while (temp > 0): total = total + (temp%10) temp = temp//10

   if num%total==0: print("Harshad Number") else: print("Not Harshad Number") task5(156) Harshad Number task5(113) Not Harshad Number

6. Write a Python program to print all pronic numbers between 1 and 100? sol: i = 0 while True: pronicNum = i*(i+1) i = i + 1 if pronicNum > 100: break print(pronicNum, end = ' ')

0 2 6 12 20 30 42 56 72 90
