Keyword-only arguments
- [Instructor] Another similarity that Python has with some other programming languages is that it provides away for specifying function parameters using keywords. So for example, you can define a function that takes positional arguments along with keyword arguments that take optional values like this. Then, when you want to call the function, you can specify values by position or by keyword. In some cases however, you may want to require the callers of your particular function specify arguments using keywords only in order to provide better readability of the code. So for example, suppose we have a function that performs a critical operation. And it provides an option to suppress exceptions. So one way to write this function would be to specify a regular argument and have it default to a certain value. Now the problem with this approach is that the function can be invoked just by passing a regular positional argument. And since this parameter has a significant effect on how the…
