不可变对象: 对于问题2,“Python函数参数对于可变对象,函数内对参数的改变会影响到原始对象;对于不可变对象,函数内对参数的改变不会影响到原始参数”。因为对默认参数,函数只会赋值一次,如果其为可变对象,那么函数内部是指节对该对象进行操作修改,而若为为不可变对象,那么函数内部改变的是函数内变量的指向对象。 二....

results = Parallel(n_jobs=2)(delayed(square)(x) for x in data) ``` 这个代码将数据data分成两块,交给两个处理器或核心并行地执行square函数,并将结果合并成一个列表results。其中n_jobs参数指定了最大并行度为2。 4. 合并结果 在所有任务都执行完成之后,需要将每个处理器或核心计算得到的结果合并成最终...
