首先,逗号(,)是Python中tuple数据结构的语法;上面的语法会执行一下的操作: 1、Python会先将右边的a, b生成一个tuple(元组),存放在内存中; 2、之后会执行赋值操作,这时候会将tuple拆开; 3、然后将tuple的第一个元素赋值给左边的第一个变量,第二个元素赋值给左边第二个变量。 再举个tuple拆分的例子: In [1...

A Boolean literal can have any of the two values: True or False. Collection literals: There are four different literal collections List literals, Tuple literals, Dict literals, and Set literals. Special literals: Python contains one special literal i.e. None. We use it to specify that field...
