可用CreateDataStructure创建新的"Deque": In[1]:= Out[1]= ds被初始化为空: In[2]:= Out[2]= 往ds中添加一个元素: In[3]:= Out[3]= ds不再为空: In[4]:= Out[4]= 它有一个元素: In[5]:= Out[5]= 再添加另一个元素并查看. 下面显示第一个元素: ...

我们看Python文档中的解释 the rule exists that only the thread that has acquired the GIL may operate on Python objects or call Python/C API functions. In order to emulate concurrency of execution, the interpreter regularly tries to switch threads (see sys.setcheckinterval()). The lock is also...

deque最前面的元素位于leftblock中,其下标是leftindex,例子中为62,即data数组倒数第二个;最后的元素位于rightblock中,其下标为rightindex,例子中为1,即data数组第二个。 当我们调用append方法添加元素时,元素最终保存在rightblock中。例子中data数组仍有空闲空间,因此只需将rightindex加一,并将新元素保存在data数组对应...
