首先,我们导入print_function和argparse模块。通过从__future__库导入print_function,我们可以像在 Python 3.X 中编写打印语句一样编写它们,但仍然在 Python 2.X 中运行它们。这使我们能够使配方与 Python 2.X 和 3.X 兼容。在可能的情况下,我们在本书中的大多数配方中都这样做。 在创建有关配方的一些描述性...
# 使用 subprocess 执行命令 process = subprocess.Popen(execute_command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) # 等待较长时间,例如 30 秒 timeout_seconds = 30 start_time = time.time() while time.time() - start_time < timeout_seconds: if process.poll() is not None:...
python/tuple,来创建一个元组,而不是默认的list。键的文本使用了一个流类型的 YAML 值["a", "b"]。 JSON 没有集合的规定。YAML 允许我们使用!!set标签来创建一个集合,而不是一个简单的序列。集合中的项目以?前缀标识,因为它们被认为是一个映射的键,没有值。 请注意,!!set标签与集合中的值处于相同的缩...
Lets call the basename of the main path, and entry point. The names of these must of course be different. Then the created binary can execute either entry point, and will react to whatsys.argv[0]appears to it. So if executed in the right way (with something likesubprocessor OS API yo...

The statement print("Hello, World") in this example will never execute because that statement appears after the function’s return statement. Identifying dead code and removing it is a good practice that you can apply to write better functions....
+1。你的和twisted答案是每隔x秒运行一个函数的唯一答案。其余的在每次调用后执行该函数延迟x秒。 如果你在哪里添加一些代码,这需要超过一秒...它会抛出时间并开始落后...在这种情况下接受的答案是正确的...任何人都可以循环一个简单的打印命令让它每秒都运行一次... 由于存在的影响...
