🚀 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

🚀 Day 20/150 – Area of a Triangle in Python

Calculating the area of a triangle is a classic beginner-friendly problem that helps you understand formulas, user input, and different coding styles in Python.

The most common formula is:

$$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$$

Let’s explore multiple ways to implement this 👇

🔹 Method 1 – Basic Method (Direct Calculation)

base = 10 height = 5 area = 0.5 * base * height print("Area of triangle:", area)

🧠 Explanation:

• We directly assign values to base and height.
• 0.5 * base * height calculates the area.
• Simple and easy to understand.

👉 Best for: Quick calculations and beginners.

🔹 Method 2 – Taking User Input

base = float(input("Enter base: ")) height = float(input("Enter height: ")) area = 0.5 * base * height print("Area of triangle:", area)

🧠 Explanation:

• input() allows user interaction.
• float() converts input into numbers.
• Same formula is applied afterward.

👉 Best for: Dynamic, real-world scenarios.

🔹 Method 3 – Using a Function

def triangle_area(b, h): return 0.5 * b * h print(triangle_area(10, 5))

🧠 Explanation:

• Function triangle_area() takes b and h as parameters.
• return gives back the computed value.
• Makes code reusable and clean.

👉 Best for: Structured and reusable programs.

🔹 Method 4 – Using Lambda Function

area = lambda b, h: 0.5 * b * h print(area(10, 5))

🧠 Explanation:

• lambda is a short, one-line function.
• Useful for simple operations without defining a full function.

👉 Best for: Short and quick logic.

Day 10: Dictionaries in Python – Mastering Key-Value Data

Dictionaries are one of the most powerful and widely used data structures in Python. They allow you to store and manage data in a key-value format, which makes them extremely efficient for searching, mapping, and organizing structured information.

If lists are about ordered collections, dictionaries are about meaningful relationships between data.

---

 What is a Dictionary?

A dictionary is an unordered, mutable collection of key-value pairs.

student = {
    "name": "Piyush",
    "age": 20,
    "course": "Python"
}

Key Points:

• Keys must be unique and immutable (string, number, tuple)
• Values can be of any data type
• Dictionaries are defined using {}

 Why Dictionaries are Important?

• Fast lookup time: O(1) average complexity
• Used in JSON data (APIs)
• Core structure in backend and data science workflows
• Ideal for representing real-world entities

---

 Creating Dictionaries

# Empty dictionary
data = {}

# Using dict()
data = dict(name="Piyush", age=20)

# Nested dictionary
student = {
    "name": "Piyush",
    "marks": {
        "math": 90,
        "science": 85
    }
}

---

 Accessing Values

student = {"name": "Piyush", "age": 20}

print(student["name"])      # Direct access
print(student.get("age"))   # Safe access

Difference:

• [] → Raises error if key not found
• .get() → Returns None (or default value)

---

 Accessing Nested Dictionary

student = {
    "name": "Piyush",
    "marks": {
        "math": 90,
        "science": 85
    }
}

print(student["marks"]["math"])  # 90

Safe Way:

print(student.get("marks", {}).get("math"))

---

 Adding and Updating Values

student = {"name": "Piyush"}

# Add new key
student["age"] = 20

# Update existing key
student["name"] = "Rahul"

---

 Removing Elements

student = {"name": "Piyush", "age": 20}

student.pop("age")
del student["name"]
student.clear()

---

 Dictionary Methods

student = {"name": "Piyush", "age": 20}

student.keys()
student.values()
student.items()

---

 Looping Through Dictionary

student = {"name": "Piyush", "age": 20}

for key in student:
    print(key, student[key])

for key, value in student.items():
    print(key, value)

---

 Real-World Example: Frequency Counter

nums = [1, 2, 2, 3, 3, 3]

freq = {}
for num in nums:
    freq[num] = freq.get(num, 0) + 1

print(freq)

---

Practice Questions

Basic

1. Create a dictionary with 3 key-value pairs and print it
2. Access a value using a key
3. Add a new key-value pair
4. Update an existing value

---

Intermediate

5. Check if a key exists in a dictionary
6. Print all keys and values separately
7. Merge two dictionaries
8. Count frequency of elements in a list using dictionary

---

Advanced

9. Create a nested dictionary for 3 students with marks
10. Sort a dictionary by keys and values
11. Invert a dictionary (swap keys and values)
12. Group elements based on frequency
