🚀 Day 40/150 – Find HCF of Two Numbers in Python

 

🚀 Day 40/150 – Find HCF of Two Numbers in Python

HCF (Highest Common Factor) is the greatest number that divides two numbers exactly.

Examples:
HCF of 12 and 18 = 6
HCF of 20 and 30 = 10

It is also called GCD (Greatest Common Divisor).

Let’s explore different ways to find HCF in Python 👇

🔹 Method 1 – Using for Loop

a = 12 b = 18 hcf = 1 for i in range(1, min(a, b) + 1): if a % i == 0 and b % i == 0: hcf = i print("HCF:", hcf)

✅ Simple beginner-friendly method.

🔹 Method 2 – Taking User Input

a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
hcf = 1

for i in range(1, min(a, b) + 1):
    if a % i == 0 and b % i == 0:
        hcf = i

print("HCF:", hcf)

✅ Useful for dynamic programs.

🔹 Method 3 – Using Euclidean Algorithm

a = 12 b = 18 while b != 0: a, b = b, a % b print("HCF:", a)

✅ Fastest and most efficient method.

🔹 Method 4 – Using Function

def hcf(a, b):
    while b != 0:
        a, b = b, a % b
    return a

print(hcf(12, 18))

✅ Clean and reusable.

🎯 Output

HCF: 6

🔑 Key Takeaways

• HCF = greatest common divisor of two numbers.
• Use % to check common factors.
• Euclidean algorithm is fastest.
• math.gcd() is built-in shortcut.

Python Coding Challenge - Question with Answer (ID -040526)

Explanation:

🧠 1. List Creation

x = [1,2,3]

Here, a list named x is created with elements:

Index 0 → 1

Index 1 → 2

Index 2 → 3

👉 So the list looks like:

x = [1, 2, 3]

🔍 2. Understanding x[0]

x[0] means accessing the element at index 0

Value at index 0 is 1

👉 So:

x[0] = 1

🔄 3. Evaluating x[x[0]]

Replace x[0] with its value:

x[x[0]] = x[1]

Now access index 1 of the list:

x[1] = 2

🖨️ 4. Final Output

print(x[x[0]]) becomes:

print(2)

✅ Final Result

Python Coding challenge - Day 1137| What is the output of the following Python Code?

 

Code Explanation:

🔹 1. Initializing the List

funcs = []

An empty list funcs is created

This list will store functions

🔹 2. Starting the Loop

for i in range(3):

Loop runs 3 times with values:

i = 0, 1, 2

🔹 3. Defining the Function Inside Loop

def f():

    return i

A function f is defined in each iteration

⚠️ Important: The function does not store the current value of i immediately

Instead, it refers to i (late binding)

👉 This means:

All functions will look up i when they are called, not when they are created

🔹 4. Appending Function to List

funcs.append(f)

The function f is added to the list

After loop ends, funcs contains 3 functions

🔹 5. After Loop Ends

Final value of i is:

i = 2

All functions refer to this same i

🔹 6. Calling the Functions

print([f() for f in funcs])

Each function is called one by one

Each function returns the current value of i, which is 2

🔹 ✅ Final Output

[2, 2, 2]

Python Coding challenge - Day 1136| What is the output of the following Python Code?

 

Code Explanation:

🔹 1. Metaclass Definition

class Meta(type):

    def __new__(cls, name, bases, dct):

        dct['x'] = 100

        return super().__new__(cls, name, bases, dct)

Meta is a metaclass (inherits from type)

__new__ runs when a class is being created, not an object

It receives the class attributes in dct

It modifies the class dictionary by setting:

x = 100

🔹 2. Class Creation (A)

class A(metaclass=Meta):

    x = 10

Python sends this class definition to the metaclass

Internally:

Meta.__new__(Meta, 'A', (), {'x': 10})

The metaclass changes:

{'x': 10} → {'x': 100}

🔹 3. Final Class Structure

After metaclass processing, class A becomes:

class A:

    x = 100

The original x = 10 is overwritten

🔹 4. Object Creation

obj = A()

Creates an instance of class A

obj itself has no x attribute

🔹 5. Attribute Lookup

print(obj.x)

Python checks:

obj → not found

class A → finds x = 100

🔹 ✅ Final Output

100

🚀 Day 38/150 – Prime Number Check in Python

A Prime Number is a number greater than 1 that has only two factors: 1 and itself.

Examples:
2, 3, 5, 7, 11 → Prime Numbers
4, 6, 8, 9 → Not Prime Numbers

Let’s explore different ways to check prime number in Python 👇

🔹 Method 1 – Using for Loop

n = 7 is_prime = True if n <= 1: is_prime = False else: for i in range(2, n): if n % i == 0: is_prime = False break print("Prime Number" if is_prime else "Not Prime Number")

Simple beginner-friendly method.

---

🔹 Method 2 – Taking User Input

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

if n <= 1:
    is_prime = False
else:
    for i in range(2, n):
        if n % i == 0:
            is_prime = False
            break

print("Prime Number" if is_prime else "Not Prime Number")

Useful when you want to test different numbers.

🔹 Method 3 – Optimized Using √n

n = 29
is_prime = True

if n <= 1:
    is_prime = False
else:
    for i in range(2, int(n ** 0.5) + 1):
        if n % i == 0:
            is_prime = False
            break

print("Prime Number" if is_prime else "Not Prime Number")

 More efficient because factors repeat after the square root.

🔹 Method 4 – Using while Loop

n = 13 i = 2 is_prime = True if n <= 1: is_prime = False else: while i < n: if n % i == 0: is_prime = False break i += 1 print("Prime Number" if is_prime else "Not Prime Number")

Same logic, just using a different loop.

---

💡 Key Takeaways

1)Prime numbers have exactly two factors
2)Numbers less than or equal to 1 are not prime
3)Checking up to √n is faster than checking all numbers
4)The optimized method is better for larger values
