One of the first things that should stick out is that we’re using themock.patchmethod decorator to mock an object located atmymodule.os, and injecting that mock into our test case method. Wouldn’t it make more sense to just mockositself, rather than the reference to it atmymodule.os...

is just a simple way to run several processes to do your work. Python environment has nothing to do with balancing load on cores/processors. multiprocessing.Processmultiprocessing.Pool If you want to control how will processor time be given to processes, you should try tweaking your OS, not ...

iterable技巧 ▍1、创建一个数字序列(从0到10,间隔为2) >>>range(0,10,2)[0, 2, 4, 6, 8] ▍2、对一串数字求和(从0到10,间隔为2) >>> l = range(0,10,2)>>>sum(l)20 ▍3、检查序列中的任一元素是否为True >>>any(a %2forainrange(0,10,2))True ...
