4. Core Concepts in Python 3 Programming

Mastering the basics is essential for building a strong foundation in Python programming.

4.1. Syntax and Basic Structures

  • Variables: Used to store data; dynamically typed (no need to declare types).

    name = "Alice"
age = 30
pi = 3.14159

  • Data Types:

    • Integers: Whole numbers (e.g., 10, -5).
    • Floats: Decimal numbers (e.g., 3.14, -2.5).
    • Strings: Sequences of characters (e.g., "Hello", "Python").
    • Booleans: True or False values.
    • Lists: Ordered, mutable collections of items (e.g., [1, 2, "three"]).
    • Tuples: Ordered, immutable collections of items (e.g., (1, 2, "three")).
    • Dictionaries: Key-value pairs (e.g., {"name": "Alice", "age": 30}).
    • Sets: Unordered collections of unique items (e.g., {1, 2, 3}).

  • Operators: Symbols used to perform operations (e.g., +, -, *, /, ==, !=).

  • Control Flow Statements:

    • if Statements: 
      age = 20
if age >= 18:
    print("Eligible to vote")
else:
    print("Not eligible to vote")
    • for Loops: 
      fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
    print(fruit)
    • while Loops: 
      count = 0
while count < 5:
    print(count)
    count += 1

  • Functions: Reusable blocks of code.

    def greet(name):
    return "Hello, " + name + "!"

print(greet("Bob"))

4.2. Object-Oriented Programming (OOP)

  • Classes: Blueprints for creating objects.

    class Dog:
    def __init__(self, name, breed):
        self.name = name
        self.breed = breed

    def bark(self):
        return "Woof!"

  • Objects: Instances of classes.

    my_dog = Dog("Buddy", "Golden Retriever")

  • Inheritance: Creating new classes from existing classes.

    class Bulldog(Dog):
    def bark(self):
        return "Ruff!"

  • Polymorphism: Ability of different classes to respond to the same method call in their own way.

    def speak(animal):
    print(animal.bark())

speak(my_dog) # Output: Woof!
speak(Bulldog("Spike", "Bulldog")) # Output: Ruff!

4.3. Data Structures and Algorithms

Understanding common data structures and algorithms is crucial for efficient problem-solving.

  • Common Data Structures:
    • Lists: Dynamically sized, mutable sequences.

    • Queues: FIFO (First-In-First-Out) data structure.
    • Stacks: LIFO (Last-In-First-Out) data structure.
  • Basic Algorithms:
    • Sorting: Arranging elements in a specific order (e.g., bubble sort, merge sort).
    • Searching: Finding specific elements in a collection (e.g., linear search, binary search).
    • Recursion: Solving a problem by breaking it down into smaller instances of the same problem.

5. Advanced Python 3 Concepts

Once you’ve grasped the basics, delving into advanced topics will enhance your skills and broaden your capabilities.

my_iterator = iter(my_list)
print(next(my_iterator)) # Output: 1
print(next(my_iterator)) # Output: 2
print(next(my_iterator)) # Output: 3

  • Generators: Functions that produce a sequence of values using the yield keyword, allowing efficient memory usage for large datasets.

    def generate_numbers(n):
    for i in range(n):
        yield i

for num in generate_numbers(5):
    print(num)

5.2. Decorators and Metaclasses

  • Decorators: Functions that modify the behavior of other functions or methods.

    def my_decorator(func):
    def wrapper():
        print("Before calling the function.")
        func()
        print("After calling the function.")
    return wrapper

@my_decorator
def say_hello():
    print("Hello!")

say_hello()

  • Metaclasses: Classes that define how other classes are created, allowing advanced customization and control over class behavior.

5.3. Concurrency and Multiprocessing

  • Threads: Lightweight processes that run concurrently within a single program.
