Python is a powerful, object-based, high-level programming language with dynamic typing and binding. Due to its flexibility and power, developers often employ certain rules, or Python design patterns. What makes them so important and what do does this me
# You can unpack tuples (or lists) into variables a, b, c = (1, 2, 3) # a is now 1, b is now 2 and c is now 3 # You can also do extended unpacking a, *b, c = (1, 2, 3, 4) # a is now 1, b is now [2, 3] and c is now 4 # Tuples are created by de...
可变参数*args 和 **kwargs定义函数时候,参数args在前,kwargs在后,*args和kwargs组合起来可以传入任意的参数。 *args参数:可接受任意个位置参数,当函数调用时,所有未使用(未匹配)的位置参数会在函数内自动组装进一个tuple对象中,此tuple对象会赋值给变量名args。 **kwargs参数:可接受任意个关键字参数,当函数调用...

你也可以混着用.命名参数首先获得参数值然后所有的其他参数都传递给*args和**kwargs.命名参数在列表的最前端.例如: def table_things(titlestring, **kwargs) *args和**kwargs可以同时在函数的定义中,但是*args必须在**kwargs前面. 当调用函数时你也可以用*和**语法.例如: >>> def print_three_things(...
