Python Day- Looping-Exercises and tasks

Prime Numbers:
Numbers which are divisible by 1 and itself are called as prime numbers.(Eg-->3,5,7)

1) Find prime number or not:

no = int(input("Enter no. "))
div = 2
while div<no: if no print prime break div else:>



<p>Output:<br>
</p>

<pre class="brush:php;toolbar:false">1)Enter no. 5
  Prime
2)Enter no. 6
  Not Prime

2) Reversing the input number and find whether that reversed number is prime number or not:

def reverse_a_no(no):
    reverse = 0
    while no>0:
        rem = no%10
        reverse = (reverse*10) + rem
        no//=10 #no=no//10
    return reverse

no = int(input("Enter no. ")) 
reversed_no = reverse_a_no(no) #31 71
print(reversed_no)
def find_prime(no):
    div = 2
    while div<no: if no return false break div else: true result1="find_prime(no)" result2="find_prime(reversed_no)" result2: print number emirp>



<p>Output:<br>
</p>

<pre class="brush:php;toolbar:false">1)Enter no. 15
  51
  EMIRP number
2)Enter no. 14
  41
  not EMIRP number

Perfect Number
Perfect number means sum of its divisible numbers will be equal that number.(eg-->6 is divisible by 1,2,3 and 1 2 3=6)

def find_perfect(no):
    total = 0
    div = 1
    while div<no: if no total="total" div else: no: return true false no. result="find_perfect(no)" true: print number perfect>



<p>Output:<br>
</p>

<pre class="brush:php;toolbar:false">Enter no. 6
Perfect Number

Square root:

Find square of an input number and sum of digits of that square root number.

def square(no):
    return no**2

no=int(input("Enter the number:"))
result=square(no)

def sum_of_digits(num):
        sum=0
        while num>0:
            sum=sum+num%10
            num=num//10
        return sum

if result



<p>Output:<br>
</p>

<pre class="brush:php;toolbar:false">Enter the number:4
7

In above example given input number is 4,
-->square root of 4 is 4x4=16
-->sum of digits of that square number 1 6=7.

Task -1 **
**Automorphic Number

Check if a number’s square ends with the same number.
Example: 5 → Automorphic (5²=25), 6 → Automorphic (6²=36), 7 → Not Automorphic.

def square(no):
    return no**2

no=int(input("Enter the number:"))
result=square(no)
print(result)

while result>0:
    rem=result%10
    if rem==no:
        print("Automorphic number")
        break
    else:
        print("Not Automorphic number")
        break

Output:

1)Enter the number:5
  25
  Automorphic number
2)Enter the number:4
  16
  Not Automorphic number

Task:2
Fibonacci Sequence

Generate the Fibonacci sequence up to a given number.
Example: Input: 10 → Output: 0, 1, 1, 2, 3, 5, 8.

no = int(input("Enter the number of required sequence: "))

first_num,sec_num =0 ,1

while first_num 



<p>Output:<br>
</p>

<pre class="brush:php;toolbar:false">Enter the number of required sequence: 10
0 1 1 2 3 5 8
