certainly! python keyword arguments are a powerful feature that enhance the flexibility and readability of your code. in this tutorial, we'll explore what keyword arguments are, how to use them, and discuss their benefits with code examples.
what are keyword arguments?
in python, when you define a function, you can specify parameters that the function can accept. when calling that function, you can provide arguments either positionally or by using keyword arguments.
*keyword arguments* allow you to specify the arguments by their parameter names, rather than just by their order. this can make your code more readable and allow you to skip optional parameters.
defining functions with keyword arguments
here's how you can define a function that uses keyword arguments:
in this function:
`name` is a required parameter.
`age` and `city` are optional parameters with default values.
calling functions with keyword arguments
you can call the function using keyword arguments as follows:
output
the output of the above function calls will be:
benefits of using keyword arguments
1. **readability**: keyword arguments make it clear what each argument represents. this is especially helpful in functions with many parameters.
2. **flexibility**: you can specify only the parameters you want to provide values for while relying on defaults for others.
3. **order independence**: you can pass arguments in any order when using keyword arguments. this allows for greater flexibility in how you call functions.
advanced usage: combining positional and keyword arguments
you can mix positional and keyword arguments in a single function call:
unpacking arguments
you can also pass dictionaries to functions using unpacking. this is particularly useful when you have many parameters:
