3. Foundational Concepts of Programming

Before writing complex programs, master the fundamental concepts that underpin all programming languages.

3.1. Variables and Data Types

Variables: Variables are used to store data. Each variable has a name and a value.
Data Types: Common data types include:
- Integers: Whole numbers (e.g., 1, 100, -5).
- Floats: Decimal numbers (e.g., 3.14, 2.5).
- Strings: Text (e.g., “Hello”, “Programming”).
- Booleans: True or False values.

3.2. Operators and Expressions

Operators: Symbols that perform operations on variables and values (e.g., +, -, *, /, =).
Expressions: Combinations of variables, values, and operators that result in a value (e.g., x + 5, a * b).

3.3. Control Structures: Conditionals and Loops

Conditionals (if, else, elif): Used to execute different code blocks based on conditions. For example:
```
if x > 10:
    print("x is greater than 10")
else:
    print("x is not greater than 10")
```

Loops (for, while): Used to repeat a block of code multiple times. For example:

for i in range(5):
    print(i)  # Output: 0, 1, 2, 3, 4

while x < 10:
    print(x)
    x += 1

3.4. Functions and Modularity

Functions: Reusable blocks of code that perform a specific task. They help organize code and avoid repetition. For example:
```
def greet(name):
    print("Hello, " + name + "!")

greet("Alice")  # Output: Hello, Alice!
```
Modularity: Breaking down a program into smaller, manageable modules or functions. This makes the code easier to understand, test, and maintain.

def multiply(x, y):
    return x * y

def divide(x, y):
    if y == 0:
        return "Cannot divide by zero"
    return x / y

print("Select operation:")
print("1. Add")
print("2. Subtract")
print("3. Multiply")
print("4. Divide")

choice = input("Enter choice(1/2/3/4): ")

num1 = float(input("Enter first number: "))
num2 = float(input("Enter second number: "))

if choice == '1':
    print(num1, "+", num2, "=", add(num1, num2))

elif choice == '2':
    print(num1, "-", num2, "=", subtract(num1, num2))

elif choice == '3':
    print(num1, "*", num2, "=", multiply(num1, num2))

elif choice == '4':
    print(num1, "/", num2, "=", divide(num1, num2))

else:
    print("Invalid input")

7.3. To-Do List Application

Build a simple to-do list application that allows users to add, remove, and view tasks.

todo_list = []

def add_task(task):
    todo_list.append(task)
    print("Task added: " + task)

def remove_task(task):
    if task in todo_list:
        todo_list.remove(task)
        print("Task removed: " + task)
    else:
        print("Task not found.")

def view_tasks():
    if not todo_list:
        print("No tasks in the list.")
    else:
        print("Tasks:")
        for i, task in enumerate(todo_list):
            print(f"{i+1}. {task}")

while True:
    print("nOptions:")
    print("1. Add task")
    print("2. Remove task")
    print("3. View tasks")
    print("4. Exit")

    choice = input("Enter choice(1/2/3/4): ")

    if choice == '1':
        task = input("Enter task: ")
        add_task(task)
    elif choice == '2':
        task = input("Enter task to remove: ")
        remove_task(task)
    elif choice == '3':
