inner uses:

y → its own parameter

x → from outer function

👉 This is called a closure:

Inner function remembers the value of x even after outer finishes

🔹 4. Returning Inner Function

return inner

✅ Explanation:

outer does NOT return a value directly

It returns the function inner itself

🔹 5. Calling Outer Function

f = outer(5)

🔍 What happens:

outer(5) is executed

x = 5

Returns inner function

👉 Now:

f → inner (with x = 5 stored)

🔹 6. Calling Returned Function

Python Coding Challenge - Question with Answer (ID -060526)

 

Explanation:

🔹 Step 1: Create Generator

x = (i for i in range(4))

This creates a generator object

Values generated:

0, 1, 2, 3

⚠️ Important:

Generator values are used only once

After consuming values → generator becomes empty 😈

🔹 Step 2: Execute sum(x)

sum(x)

Python starts consuming generator values:

0 + 1 + 2 + 3 = 6

👉 Result:

6

⚠️ Now generator x is exhausted:

x → empty

🔹 Step 3: Execute max(x, default=0)

max(x, default=0)

But generator already consumed all values ❗

So internally:

max([], default=0)

👉 Since generator is empty:

default=0 is returned

👉 Result:

0

🔹 Step 4: Print Final Output

print(6, 0)

👉 Output:

6 0

The LCM (Least Common Multiple) of two numbers is the smallest number that is divisible by both numbers.

Example:
LCM of 4 and 6 = 12

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

🔹 Method 1 – Using Loop

a = 4 b = 6 greater = max(a, b) while True: if greater % a == 0 and greater % b == 0: print("LCM:", greater) break greater += 1

✅ Starts from the greater number and checks multiples.

🔹 Method 2 – Taking User Input
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))

greater = max(a, b)

while True:
    if greater % a == 0 and greater % b == 0:
        print("LCM:", greater)
        break
    greater += 1





✅ Dynamic version using user input.
🔹 Method 3 – Using GCD Formula
Formula:
LCM = (a × b) // GCD(a, b)
import math

a = 4
b = 6

lcm = (a * b) // math.gcd(a, b)

print("LCM:", lcm)




✅ Fastest and most efficient method.
🔹 Method 4 – Using Function
import math

def find_lcm(a, b):
    return (a * b) // math.gcd(a, b)

print(find_lcm(4, 6))




✅ Reusable and clean code.
🔹 Output
LCM: 12


🔥 Key Takeaways

Python Coding challenge - Day 1143| What is the output of the following Python Code?

 

Code Explanation:

🔹 1. Class Definition

class Test:

✅ Explanation:

A class Test is created.

It will store a list in each object.

🔹 2. Constructor (__init__)

def __init__(self, x=[]):

    self.x = x

✅ Explanation:

Constructor runs when object is created.

Parameter x=[] is a default argument.

⚠️ Important:

This list is created only once

It is shared across all objects

🔹 3. Assigning to Instance

self.x = x

✅ Explanation:

Assigns the same list (x) to the object

Since x is shared → all objects refer to same list

🔹 4. Creating First Object

a = Test()

✅ What happens:

No argument passed → uses default list []

So:

a.x → []

🔹 5. Creating Second Object

b = Test()

✅ What happens:

Again uses SAME default list

So:

b.x → []

⚠️ Key Insight:

a.x is b.x → True

👉 Both refer to same list

🔹 6. Modifying List via a

a.x.append(1)

✅ Explanation:

Adds 1 to the shared list

So now:

a.x → [1]

b.x → [1]

🔹 7. Printing b.x

print(b.x)

✅ Output:

[1]

Final Output:

[1]

def func(x, lst=[]):

✅ Explanation:

A function func is defined with:

x → number of iterations

lst=[] → default list

⚠️ Important:

This list is created only once (when function is defined, not called)

It is shared across all function calls

🔹 2. Loop Execution

for i in range(x):

✅ Explanation:

Loop runs from 0 to x-1

Adds numbers step by step

🔹 3. Appending Values

lst.append(i)

✅ Explanation:

Adds i into the same list lst

Since lst is shared → values accumulate over calls

🔹 4. Returning List

return lst

✅ Explanation:

Returns the updated list

🔹 5. First Function Call

print(func(3))

🔍 Execution:

x = 3

Loop runs: 0,1,2

List becomes:

[0, 1, 2]

✔️ Output:

[0, 1, 2]

🔹 6. Second Function Call

print(func(2))

🚨 Important:

Python does NOT create a new list

It uses the SAME previous list → [0,1,2]

🔍 Execution:

x = 2

Loop runs: 0,1

These values are appended to existing list:

[0,1,2] + [0,1] → [0,1,2,0,1]

✔️ Output:

[0, 1, 2, 0, 1]

🎯 Final Output

[0, 1, 2]

[0, 1, 2, 0, 1]
