optional parameters,可选形参(携带默认值) 2.1 必须形参(Required parameters) 必须形参决定了哪些实参在函数调用时必须传递,而且传递的实参数量必须刚刚好与必须形参的数量对应(不能多也不能少)。 强制参数的函数,我们安排脚本文件func_params_types.py。 def check_passwd(username, password): if len(password) ...
We can also mix these two types of arguments. This is typically effective when we want to use a function with a few mandatory parameters but lots of optional parameters. For example, we can pass two positional arguments to the two corresponding mandatory parameters, then skip the first ...

The solutions based on list comprehensions are usually more readable than the solutions based on higher-order functions, and we have favored the former approach throughout this book(使用列表解析的方法可读性更好). Named Arguments 参数命名 When there are a lot of parameters it is easy to get con...

In this format, port is optional. In the IPv6 scenario, the value format is as follows: sftp://username:password@hostname:port/path The value of hostname can be a domain name or an IP address. If the value is a domain name, the format is sftp://username:password@hostname:port/...
