Nested Conditionals

Nested conditionals are if statements placed inside other if, elif, or else blocks. They allow for more complex decision-making where conditions depend on the outcome of previous conditions. While elif handles mutually exclusive conditions well, nested conditionals are useful when you need to check additional conditions only if certain outer conditions are met. However, deeply nested conditionals can become difficult to read and maintain, so they should be used judiciously. Alternatives to deep nesting include using logical operators (and, or) to combine conditions, breaking complex conditionals into separate functions, or using early returns. Despite potential readability concerns, nested conditionals are sometimes the most straightforward way to express complex logic, particularly when decisions are hierarchical or when later conditions only make sense in the context of earlier ones being true.
