Okay, let's dive deep into using multiple conditions within `if` statements. This is a crucial concept for writing effective and flexible logic in any programming language. I'll cover the core ideas, syntax, common scenarios, and best practices.

**The Foundation: `if`, `else if`, and `else`**

Before we get into multiple conditions, let's quickly recap the basic structure of an `if` statement:
And the extended version:
* **`if`:** The starting point. The code block under the `if` statement is executed only if the condition is evaluated to `True`.
* **`elif` (else if):** Provides additional conditions to check. An `elif` block is only checked if the preceding `if` (or `elif`) condition was `False`. You can have zero or many `elif` blocks.
* **`else`:** An optional block that executes only if *none* of the preceding `if` or `elif` conditions were `True`. You can have at most one `else` block.

**Combining Conditions: `and`, `or`, and `not`**

This is where the real power comes in. We use logical operators to create complex conditions by combining simpler ones:

* **`and`:** The entire condition is `True` only if *both* the conditions on either side of `and` are `True`.



In this example, the message "You are eligible to drive." is printed only if `age` is 16 or greater *and* `has_license` is `True`. If either condition is `False`, the `else` block is executed.

* **`or`:** The entire condition is `True` if *at least one* of the conditions on either side of `or` is `True`.



Here, the message "Enjoy your free time!" is printed if `is_weekend` is `True` *or* if `is_holiday` is `True` (or if both are `True`). The `else` block is only executed if *both* are `False`.

* **`not`:** This operator negates a condition. If a condition is `True`, `not condition` is `False`, and vice versa.



In this example, the message "Let's go for a walk!" is printed only if `is_raining` is `False`.
