🚀 Day 29/150 – Sum of First N Natural Numbers in Python

Finding the sum of first N natural numbers is a classic beginner problem that helps you understand loops, formulas, and basic arithmetic in Python.

👉 Natural numbers start from 1
Examples: 1, 2, 3, 4, 5...

If N = 5

Sum = 1 + 2 + 3 + 4 + 5 = 15

Let’s explore different methods 👇

🔹 Method 1 – Using for Loop

The most common approach.

n = 5
total = 0

for i in range(1, n + 1):
    total += i

print("Sum:", total)

✅ Explanation:

• Start total = 0
• Add each number from 1 to N
• Print final sum

🔹 Method 2 – Using Formula

Fastest mathematical solution.

n = 5

total = n * (n + 1) // 2

print("Sum:", total)

✅ Explanation:

Formula:

$$\text{Sum} = \frac{n(n+1)}{2}$$

• Very efficient
• No loop required

🔹 Method 3 – Taking User Input

Interactive version.

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

total = n * (n + 1) // 2

print("Sum:", total)


🔹 Method 4 – Using while Loop
Condition-based approach.
n = 5
i = 1
total = 0

while i <= n:
    total += i
    i += 1

print("Sum:", total)


































🎯 Final Thoughts

Use formula for best performance ⚡

Use loop methods for learning logic 🧠

What is Exception Handling?

Exception handling is the process of responding to runtime errors so that the normal flow of the program is not interrupted.

Example without Exception Handling

num = int(input("Enter a num: "))
print(10 / num)
print("Hello World")

If the user enters 0 or invalid input, the program crashes and "Hello World" will not execute.

---

try - except Block

To prevent crashes, Python provides the try-except mechanism.

• try → Code that may cause an error
• except → Code that handles the error

Basic Example

try:
    num = int(input("Enter a num: "))
    print(10 / num)
except:
    print("Something went wrong!")

print("Hello World")

Now, even if an error occurs, the program continues execution.

---

Handling Specific Exceptions

Handling specific exceptions is always better than using a general except.

Example

try:
    num = int(input("Enter a num: "))
    print(10 / num)
except ZeroDivisionError:
    print("Cannot divide by zero")
except ValueError:
    print("Invalid input! Please enter a number")
except:
    print("Unaware of the error")

print("Hello World")

This improves debugging and makes your code more precise.

---

else and finally

Python provides two additional blocks:

• else → Runs when no exception occurs
• finally → Always runs

Example

try:
    file = open("data.txt", "r")
    print(file.read())
except FileNotFoundError as e:
    print("File Not Found", e)
else:
    print("Found the file")
finally:
    print("Execution completed")

---

Multiple Exceptions in One Block

You can handle multiple exceptions together:

try:
    num = int(input("Enter a num: "))
    print(10 / num)
except (ValueError, ZeroDivisionError):
    print("Something went wrong!")

---

Using Exception Objects

You can capture the exception details using as.

try:
    x = int("abc")
except ValueError as e:
    print("Error:", e)

---

Raising Exceptions Manually

You can trigger exceptions using the raise keyword.

age = int(input("Enter age: "))

if age < 18:
    raise ValueError("You must be 18 or older")

print("Access Granted")

---

Custom Exceptions

You can define your own exception classes by inheriting from Exception.

Example

class MyError(Exception):
    pass

raise MyError("This is a custom error")

---

Real-World Example: Bank Withdrawal System

class InsufficientBalanceError(Exception):
    pass

balance = 5000
withdraw = int(input("Enter amount to withdraw"))

try:
    if withdraw > balance:
        raise InsufficientBalanceError("Not enough balance")
    else:
        print("Withdrawal successful")
except InsufficientBalanceError as e:
    print(e)

This demonstrates how custom exceptions can model real-world scenarios.

---

Best Practices

• Always handle specific exceptions instead of generic ones
• Use finally for cleanup tasks (closing files, releasing resources)
• Avoid silent failures (empty except)
• Use custom exceptions for domain-specific logic

---

Python Coding Challenge - Question with Answer (ID -240426)

 

Explanation:

🧩 Function Definition

def f(x, y=5): 

    return x + y

def is used to define a function named f.

The function takes two parameters:

x → required argument

y → optional argument with a default value of 5

return x + y means the function will output the sum of x and y.

▶️ First Function Call

print(f(3))

Only one argument (3) is passed.

So:

x = 3

y = 5 (default value is used)

Calculation:

3 + 5 = 8

Output:

8

▶️ Second Function Call

print(f(3, None))

Two arguments are passed:

x = 3

y = None (explicitly provided, so default is NOT used)

Now the function tries:

3 + None

⚠️ This causes an error because Python cannot add an integer and NoneType.

❌ Error Produced

TypeError: unsupported operand type(s) for +: 'int' and 'NoneType'

Final Output:

Error

🚀 Day 28/150 – Print Odd Numbers up to N in Python

 

🚀 Day 28/150 – Print Odd Numbers up to N in Python

Printing odd numbers up to N is a simple and useful exercise to practice loops, conditions, and number logic in Python.

👉 An odd number is any number that is not divisible by 2.

Examples: 1, 3, 5, 7, 9...

Let’s explore different methods 👇

🔹 Method 1 – Using for Loop

The easiest and most efficient way.

n = 10

for i in range(1, n + 1, 2):
    print(i)

✅ Explanation:

• Starts from 1
• Increments by 2
• Prints only odd numbers

🔹 Method 2 – Using Condition inside Loop

Check each number manually.

n = 10

for i in range(1, n + 1):
    if i % 2 != 0:
        print(i)

✅ Explanation:

• % 2 != 0 checks if the number is odd
• Prints only numbers that satisfy the condition

🔹 Method 3 – Taking User Input

Make the program dynamic.

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

for i in range(1, n + 1, 2):
    print(i)

🔹 Method 4 – Using while Loop

Condition-based approach.

n = 10
i = 1

while i <= n:
    print(i)
    i += 2

✅ Explanation:

• Starts from 1
• Runs until i <= n
• Increases by 2

 Final Thoughts

• Best method: range(1, n+1, 2) 
• Condition method improves logic building 
• while loop gives more control
