Using default parameters can make your coding easier and cleaner by reducing the number of inputs you have to provide.

Here’s how they work:

• When you set default values for parameters, you can use functions without needing to give every detail every time.

• This cuts down on repetition. It’s super helpful when certain values are often the same.

• For example, think about a function called createUser(name, age=18, role='guest'). If you want to create a user named Alice, you can just write createUser('Alice').

• This way, Alice will automatically be 18 and have the role of 'guest' without any extra work.

Default parameters also help you write more efficient code.

• They let you use one function with optional parts instead of writing many different functions for similar tasks.

• Instead of making several versions of a function, you can just have one, which makes the code cleaner and easier to follow.

Another big plus about default parameters is that they make it simpler to update your code.

• If you want to change a default value, you only need to do it one time. This means all the places that use that default will update automatically.

In summary, using default parameters in programming can:

• Make your code clearer by lowering the number of inputs you need.

• Boost your efficiency by avoiding extra functions for simple differences.

• Ease maintenance by keeping default value changes simple.

Overall, they are key for writing easier-to-read code, helping you program faster and with more confidence.
