Command Line Usag Optional parameters are a nice language feature - function parameters that are given default values if not used when calling a function. Optional parameters are great for simplifying code, and hiding advanced but not-often-used functionality. If 90% of the time you're calling a function using the same values for some parameters, you should look into making those parameters optional to avoid. This is unless we use optional arguments. In which case, we can specify fewer arguments than a function accepts because some arguments are optional. Python Optional Arguments. A Python optional argument is an argument with a default value. You can specify a default value for an argument using the assignment operator. There is no need to specify. For this, you can reference the original event args in your lambda and forward them along. < button @onclick = args => Delete(todo, args) > X </ button > This effectively forwards the arguments from the original event to your event handler, where you can do with them as you please. void Delete (Todo todo, MouseEventArgs args) {Debug

The method getopt() returns a value that further consists of two different values. The first value is basically a list of tuples. Each of these tuples. click通过click.command()装饰函数,使之成为命令行接口;通过click.option()装饰函数,为其约束并添加命令行选项和参数。简化了传统加参的方式,减少了开发者编写的代码量,使命令行工具编写起来快速而有趣。新建一个名为adduser.py的Python文件,寥寥几行代码已经实现了一个完整命令行工具
