虽然optparse是以前版本的 Python 中使用的库,但argparse已成为创建参数处理代码的替代品。ConfigParser库从配置文件中解析参数,而不是从命令行中解析。这对于需要大量参数或有大量选项的代码非常有用。在本书中,我们不会涵盖ConfigParser,但如果发现您的argparse配置变得难以维护,值得探索一下。 要了解有关argparse库的更...
使用argparse 的第一步是创建一个 ArgumentParser 对象: >>> >>> parser = argparse.ArgumentParser(description='Process some integers.') ArgumentParser 对象包含将命令行解析成 Python 数据类型所需的全部信息。 添加参数 给一个 ArgumentParser 添加程序参数信息是通过调用 add_argument() 方法完成的。通常,这些...

该argparse模块提供了更强大和灵活的命令行处理。 10.4 错误输出重定向和程序终止 该sys模块还具有stdin,stdout和stderr的属性。后者对于发出警告和错误消息非常有用,即使在重定向stdout时也可以看到它们: >>> >>> sys.stderr.write('Warning, log file not found starting a new one\n') Warning, log file...

To see this in action, create a script named stereo_booster.py that takes paths to the input and output WAV files as arguments with an optional strength parameter: Python stereo_booster.py from argparse import ArgumentParser def main(): args = parse_args() def parse_args(): parser = ...
To issue command synchronously use connector.synchronous, and to “pipeline” the requests (have multiple requests issued and “in flight” simultaneously), use connector.pipeline (see cpppo/server/enip/client/thruput.py) ap = argparse.ArgumentParser() ap.add_argument( '-d', '--depth', ...
