Note that when we call theopen()function to open the file at the starting of the program, we use"r"as the mode to read the file only. Finally, we use theifconditional statement to check the returned output at the end is an empty string. ...

比如time.sleep(1) 大概是这样实现的: { Py_BEGIN_ALLOW_THREADS(释放GIL) sleep(1); Py_END_ALLOW_THREADS(申请GIL) } 即通过两个宏来实现阻塞调度,注意阻塞调度则不会重置 PyEval_EvalFrameEx 内的 _Py_Ticker 为 初始值 _Py_CheckInterval。
