It starts the communication between Bookmap and your Python script. Call it once you have added all your Event handlers.handle_subscribe_instrument is a function that you should define. It will be called each time you enable the addon in Bookmap for a certain instrument. All handlers, ...
The built-in python functionmap[1]is not able to parallelize. multiprocessing.Pool().map[3]does not allow any additional argument to the mapped function. multiprocessing.Pool().starmapallows passing multiple arguments, but in order to pass a constant argument to the mapped function you will nee...
(function-name arg1 arg2 arg3) 其中每个参数都是s表达式, 求值以后, 传递给函数。如果我们用(+ 4 5)来代替arg1, 那么, 程序会先求出结果, 就是9, 然后把9传递给函数。宏的工作方式和函数类似。主要 的差别是, 宏的参数在代入时不求值。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 (macro-na...
In object-oriented computer programming, a null object is an object with no referenced value or with defined neutral ("null") behavior. The null object design pattern describes the uses of such objects and their behavior (or lack thereof). ...

unordered_map 容器,无序容器的底层实现都采用的是哈希表存储结构,python的字典也是如此。关于哈希表(散列表)可以查看:https://zhuanlan.zhihu.com/p/45430524 左边很明显是个数组,数组的每个成员包括一个指针,指向一个链表的头,当然这个链表可能为空,也可能元素很多。我们根据元素的一些特征把元素分配到不同的链表中...
