Introduction to Functions
In Python, a function is a block of code that performs a specific task and can optionally return a value. There are several reasons to use functions in Python:
- Code Organization: Functions help to organize and structure your code, making it easier to understand and maintain. By breaking your code down into smaller, self-contained blocks, you can improve its readability and reduce the chances of introducing bugs.
- Code Reusability: Functions allow you to reuse the same code in multiple parts of your program. This can save you time and effort, and it can also make your code more reliable and maintainable.
- Modularity: Functions allow you to build your program out of smaller, more manageable pieces. This makes it easier to test and debug your code, and it also makes it more adaptable to change.
- Abstraction: Functions provide a level of abstraction, which helps to separate the high-level logic of your program from the low-level details. This makes it easier to think about and reason about your code, and it also makes it more flexible and adaptable to change.
- Recursive problems: Functions can call themselves, and this technique is called…
