2.2. Understanding Basic Programming Concepts

Before writing complex code, grasp the fundamental concepts that underpin all programming languages, including Python. A study by Stanford University highlights that understanding these basics significantly improves learning outcomes.

Variables:
- Variables are used to store data values. In Python, you don’t need to declare the type of a variable; it’s dynamically typed.
```
x = 5       # Integer
name = "John" # String
pi = 3.14   # Float
```
Data Types:
- Python has several built-in data types:
  - Integer (int): Whole numbers (e.g., 5, -3, 0).
  - Float (float): Decimal numbers (e.g., 3.14, -0.5).
  - String (str): Text (e.g., “Hello, World!”).
  - Boolean (bool): True or False values.
  - List: An ordered collection of items (e.g., [1, 2, 3]).
  - Tuple: An ordered, immutable collection of items (e.g., (1, 2, 3)).
  - Dictionary: A collection of key-value pairs (e.g., {‘name’: ‘John’, ‘age’: 30}).
Operators:
- Operators perform operations on variables and values.
  - Arithmetic Operators: +, -, *, /, %, ** (exponentiation), // (floor division).
  - Comparison Operators: ==, !=, >, <, >=, <=.
  - Logical Operators: and, or, not.
  - Assignment Operators: =, +=, -=, *=, /=, %=.

Control Structures:

Control structures dictate the flow of execution in a program.
- Conditional Statements (if, elif, else):

age = 20
if age >= 18:
    print("You are an adult")
else:
    print("You are a minor")

Loops (for, while):

# For loop
for i in range(5):
    print(i)

# While loop
count = 0
while count < 5:
    print(count)
    count += 1

Functions:

Functions are reusable blocks of code that perform a specific task.

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

greet("Alice")  # Output: Hello, Alice!

2.3. Familiarizing Yourself With Python Syntax

Understanding Python syntax is vital for writing error-free code.

Indentation: Python uses indentation to define blocks of code, unlike other languages that use braces.

if True:
    print("This is inside the if block")  # Indented
print("This is outside the if block")      # Not indented

Comments: Use comments to explain your code.

# This is a single-line comment

'''
This is a
multi-line comment
'''

Variables Naming:
- Variable names should be descriptive and follow the snake_case convention (e.g., user_name, total_count).
- Variable names must start with a letter or underscore and can contain letters, numbers, and underscores.

Classes and Objects:

A class is a blueprint for creating objects. An object is an instance of a class.

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

    def bark(self):
        print("Woof!")

my_dog = Dog("Buddy", "Golden Retriever")
print(my_dog.name)  # Output: Buddy
my_dog.bark()      # Output: Woof!

Inheritance:

Inheritance allows a class to inherit properties and methods from another class.

class Animal:
    def __init__(self, name):
        self.name = name

    def speak(self):
        print("Generic animal sound")

class Dog(Animal):
    def speak(self):
        print("Woof!")

my_dog = Dog("Buddy")
my_dog.speak()  # Output: Woof!

Polymorphism:

Polymorphism allows objects of different classes to be treated as objects of a common type.

class Cat(Animal):
    def speak(self):
        print("Meow!")

animals = [Dog("Buddy"), Cat("Whiskers")]
for animal in animals:
    animal.speak()  # Output: Woof! Meow!

Encapsulation:

Encapsulation involves bundling data and methods that operate on that data within a class and restricting access to some of the object’s components.

class BankAccount:
    def __init__(self, account_number, balance):
        self._account_number = account_number  # Protected attribute
        self.__balance = balance              # Private attribute

    def deposit(self, amount):
        self.__balance += amount

    def get_balance(self):
        return self.__balance

my_account = BankAccount("123456789", 1000)
my_account.deposit(500)
print(my_account.get_balance())  # Output: 1500

df = pd.DataFrame(data)
print(df)

4.4. Error Handling and Debugging

Writing robust code requires effective error handling and debugging techniques.

Exception Handling:

Use try, except, finally blocks to handle exceptions gracefully.

try:
    result = 10 / 0
except ZeroDivisionError:
    print("Cannot divide by zero")
finally:
    print("Execution complete")

Debugging Tools:
- Use the pdb module for interactive debugging.
- Utilize debugging features in IDEs like PyCharm and VS Code.

Logging:

Use the logging module to record events and errors in your code.

import logging
