<h2 class="wp-block-heading" id="ii-write-pythonic-code">II. Write Pythonic Code</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>In this section, we'll explore Pythonic coding techniques with hands-on code examples. </p>
<!-- /wp:paragraph -->

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="a-comprehension">A. Comprehension</h3>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Comprehensions help you create new data structures concisely. We'll cover three types of comprehensions with code examples:</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>1. List Comprehensions: Use a single line of code to create a new list.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example: Create a list of squares for numbers from 1 to 10.</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">squares = [x ** 2 for x in range(1, 11)]
print(squares)
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>2. Set Comprehensions: Create sets using a single line of code.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example: Create a set of even numbers from 1 to 20.</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">even_numbers = {x for x in range(1, 21) if x % 2 == 0}
print(even_numbers)
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>3. Dictionary Comprehensions: Build dictionaries with key-value pairs using a single line of code.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example: Create a dictionary with numbers as keys and their squares as values.</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">number_squares = {x: x ** 2 for x in range(1, 6)}
print(number_squares)
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="b-python-lambda">B. Python Lambda</h3>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Lambda functions are small, anonymous functions. We'll cover their syntax, use cases, and limitations with code examples:</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>1. Lambda Functions: Create simple, one-time-use functions.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example: Sort a list of tuples by the second element.</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">pairs = [(1, 'one'), (2, 'two'), (3, 'three')]
sorted_pairs = sorted(pairs, key=lambda x: x[1])
print(sorted_pairs)
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>2. Use Cases and Limitations: Lambda functions are best suited for simple operations.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example: Filter even numbers from a list using lambda.</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">numbers = [1, 2, 3, 4, 5, 6]
even_numbers = list(filter(lambda x: x % 2 == 0, numbers))
print(even_numbers)
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="c-function-arguments">C. Function Arguments</h3>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>We'll explore different types of function arguments with code examples:</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>1. Default Arguments: Set default values for function parameters.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example: Greet a user with a default name.</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">def greet(name="Guest"):
    print(f"Hello, {name}!")

greet()
greet("Alice")
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>2. Keyword Arguments: Make function calls more readable by specifying parameter names.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example: Print user details with keyword arguments.</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">def print_user_details(age, name):
    print(f"Name: {name}, Age: {age}")

print_user_details(age=25, name="Bob")
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>3. Positional Arguments: Pass a specific number of arguments in a particular order.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example: Calculate the product of two numbers.</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">def product(x, y):
    return x * y

result = product(5, 3)
print(result)
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="d-variable-arguments">D. Variable Arguments</h3>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Learn how to use *args and **kwargs to accept a varying number of arguments:</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>1. *args: Pass a variable number of positional arguments.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example: Calculate the sum of an unknown number of arguments.</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">def sum_numbers(*args):
    return sum(args)

result = sum_numbers(1, 2, 3, 4, 5)
print(result)
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>2. **kwargs: Pass a variable number of keyword arguments. </p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example: Print user details with an unknown number of attributes.</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">def print_user_details(**kwargs):
    for key, value in kwargs.items():
        print(f"{key}: {value}")

print_user_details(name="Alice", age=30, city="New York")</code></pre>

<h2 class="wp-block-heading" id="iii-python-oop">III. Python OOP</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>In this section, we'll explore Python's object-oriented programming (OOP) concepts, which will help you write more structured, maintainable code.</p>
<!-- /wp:paragraph -->

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="a-understanding-oop">A. Understanding OOP</h3>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>We'll introduce you to the fundamental concepts and benefits of OOP:</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>1. Object-Oriented <a href="https://nerdleveltech.com/javascript-functions-why-theyre-essential-to-understand-easy-guide-part2/" target="_blank" rel="noreferrer noopener">Programming Concepts</a>: All about classes, objects, inheritance, encapsulation, and polymorphism.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>2. Benefits of OOP: OOP can make your code more modular, reusable, and maintainable, ultimately improving the quality of your projects.</p>
<!-- /wp:paragraph -->

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="b-classes-and-objects">B. Classes and Objects</h3>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>We'll explore how to define and work with classes and objects in Python:</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>1. Defining Classes: Create a class in Python and define its attributes and methods using simple examples.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example:</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">class Dog:
    def __init__(self, name, breed):
        self.name = name
        self.breed = breed

    def bark(self):
        print(f"{self.name} says woof!")
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>2. Instantiating Objects: Create instances of a class, which are individual objects that you can interact with.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example:</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">my_dog = Dog("Buddy", "Golden Retriever")
my_dog.bark()
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>3. Class and Instance Variables: See the difference between class variables, which are shared among all instances, and instance variables, which are unique to each instance.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example:</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">class Dog:
    species = "Canis lupus familiaris"  # Class variable

    def __init__(self, name, breed):
        self.name = name  # Instance variable
        self.breed = breed  # Instance variable
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="c-everything-is-an-object">C. Everything is an Object</h3>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Learn about Python's object model and built-in functions for working with objects:</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>1. Python's Object Model: Everything in Python is an object, including functions, modules, and even simple data types like integers and strings.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>2. The 'type' and 'id' Functions: Use the 'type' function to determine an object's class and the 'id' function to get its unique identifier.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example:</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">print(type(42))  # Output: &lt;class 'int'>
print(id(42))  # Output: Unique identifier (e.g., 10915808)
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="d-python-inheritance">D. Python Inheritance</h3>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Dive into inheritance in Python, including single and multiple inheritance, and method resolution order:</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>1. Single Inheritance: Create subclasses that inherit attributes and methods from a parent class.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example:</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">class Animal:
    def speak(self):
        pass

class Dog(Animal):
    def speak(self):
        print("Woof!")
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>2. Multiple Inheritance: Create classes that inherit from multiple parent classes.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example:</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">class A:
    def method(self):
        print("A")

class B:
    def method(self):
        print("B")

class C(A, B):
    pass

c = C()
c.method()  # Output: A
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>3. Method Resolution Order: Determines the order in which to search for methods in a class hierarchy.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example:</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">print(C.mro())  # Output: [&lt;class '__main__.C'>, &lt;class '__main__.A'>, &lt;class '__main__.B'>, &lt;class 'object'>]
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="e-oop-examples">E. OOP Examples</h3>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>We'll walk you through some practical examples to demonstrate OOP concepts in action:</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>1. Creating a Simple Class Hierarchy: Build a class hierarchy that showcases inheritance and method overriding.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example:</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">class Animal:
    def speak(self):
        print("The animal makes a sound.")

class Dog(Animal):
    def speak(self):
        print("The dog barks.")

class Cat(Animal):
    def speak(self):
        print("The cat meows.")

dog = Dog()
cat = Cat()

dog.speak()
cat.speak()
</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>2. Polymorphism and Method Overriding: Polymorphism allows you to use different implementations of the same method in different subclasses.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example:</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">def make_sound(animal):
    animal.speak()

make_sound(dog)  # Output: The dog barks.
make_sound(cat)  # Output: The cat meows.

<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>In this section, we'll explore Python exception handling, which is essential for creating robust, error-resilient code.</p>
<!-- /wp:paragraph -->

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="a-python-exceptions">A. Python Exceptions</h3>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Discover Python's built-in exceptions and how to create custom ones:</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>1. Built-in Exceptions: Take a look of the common built-in exceptions, such as <code>ValueError</code>, <code>TypeError</code>, and <code>FileNotFoundError</code>, and when they occur.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example:</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">try:
    int("abc")
except ValueError:

</code></pre>
<!-- /wp:prismatic/blocks -->

<!-- wp:paragraph -->
<p>2. 'finally' and 'else' Clauses: The use the <code>finally</code> clause to execute code regardless of whether an exception occurs, and the <code>else</code> clause to run code when no exceptions are raised.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Example:</p>
<!-- /wp:paragraph -->

<!-- wp:prismatic/blocks -->
<pre class="wp-block-prismatic-blocks"><code class="language-">try:
