🚀 Day 22/150 – Simple Interest in Python

Calculating Simple Interest (SI) is a fundamental concept in both mathematics and programming. It helps you understand how formulas translate into code and how Python can be used for real-world financial calculations.

The formula for Simple Interest is:

$$\text{SI} = \frac{P \times R \times T}{100}$$

Where:

• P = Principal amount
• R = Rate of interest
• T = Time (in years)

 

🔹 Method 1 – Direct Calculation

P = 1000
R = 5
T = 2

SI = (P * R * T) / 100

print("Simple Interest:", SI)

🧠 Explanation:

• Values are directly assigned.
• Formula is applied in one line.
• Easy to understand and quick to execute.

👉 Best for: Learning basics and testing formulas.

🔹 Method 2 – Taking User Input

P = float(input("Enter principal: "))
R = float(input("Enter rate: "))
T = float(input("Enter time (years): "))

SI = (P * R * T) / 100

print("Simple Interest:", SI)

🧠 Explanation:

• input() allows dynamic values.
• float() ensures decimal calculations.
• Makes the program interactive.

👉 Best for: Real-world scenarios.

🔹 Method 3 – Using a Function

def simple_interest(p, r, t):
    return (p * r * t) / 100

print(simple_interest(1000, 5, 2))

🧠 Explanation:

• Function improves code reusability.
• Parameters (p, r, t) make it flexible.
• return gives the calculated value.

👉 Best for: Clean and reusable code.

🔹 Method 4 – Using Lambda Function

si = lambda p, r, t: (p * r * t) / 100 print(si(1000, 5, 2))

🧠 Explanation:

• lambda creates a one-line function.
• Useful for short calculations.

👉 Best for: Quick operations.

🔹 Method 5 – Using Tuple Input (Extended)

P = 1000
R = 5
T = 2

SI = (P * R * T) / 100
Amount = P + SI

print("Simple Interest:", SI)
print("Total Amount:", Amount)

🧠 Explanation:

• Calculates both Simple Interest and Total Amount.
Amount = Principal + Interest
• Useful in financial applications.

👉 Best for: Practical use cases.

⚡ Key Takeaways

• Formula: (P × R × T) / 100
• Use:
  • Direct values → for simplicity
  • Input → for user interaction
  • Functions → for modular code
  • Lambda → for short expressions
  • Extended logic → for real applications

🚀 Day 21/150 – Perimeter of a Rectangle in Python

Understanding how to calculate the perimeter of a rectangle is one of the simplest yet important concepts in programming. It helps you build a strong foundation in working with formulas, user input, and functions in Python.

The formula for the perimeter of a rectangle is:

$$\text{Perimeter} = 2 \times (length + width)$$

Let’s explore different ways to implement this in Python 👇

---

🔹 Method 1 – Direct Calculation

This is the simplest way where we directly assign values to length and width.

length = 10
width = 5

perimeter = 2 * (length + width)

print("Perimeter of rectangle:", perimeter)

🧠 Explanation:

• We define length and width.
• Apply the formula: 2 * (length + width)
• Print the result.

👉 Best for: Beginners and quick calculations.

---

🔹 Method 2 – Taking User Input

This method makes your program interactive by allowing users to enter values.

length = float(input("Enter length: "))
width = float(input("Enter width: "))

perimeter = 2 * (length + width)

print("Perimeter of rectangle:", perimeter)

🧠 Explanation:

• input() takes user input.
• float() converts input into decimal numbers.
• Same formula is applied afterward.

👉 Best for: Real-world applications where input varies.

---

🔹 Method 3 – Using a Function

Functions make your code reusable and clean.

def find_perimeter(l, w):
    return 2 * (l + w)

print(find_perimeter(10, 5))

🧠 Explanation:

• def is used to define a function.
• l and w are parameters.
• return sends back the calculated value.

👉 Best for: Writing modular and reusable code.

---

⚡ Key Takeaways

• The formula is simple: 2 × (length + width)
• Use direct values for quick tasks.
• Use input() for interactive programs.
• Use functions for clean and reusable code.

Python Coding Challenge - Question with Answer (ID -160426)

 

Code Explanation:

🔹 Step 1: Create Tuple

a = (1, [2, 3])

A tuple is created → (1, [2, 3])

Tuple is immutable ❌

But it contains a list [2, 3], which is mutable ✅

🔹 Step 2: Perform += Operation

a[1] += [4]

This line is the main trick 😈

👉 Python internally does:

Modify the list

Then try to assign it back

🔹 Step 2.1: List Gets Modified ✅

[2, 3] → [2, 3, 4]

This works because list is mutable

🔹 Step 2.2: Tuple Assignment Fails ❌

a[1] = [2, 3, 4]

Python tries to reassign value inside tuple

❌ Not allowed → tuple is immutable

👉 So error occurs:

TypeError: 'tuple' object does not support item assignment

Final Output:

Error
