PdArgumentParser
(dataclass_types: Union[DataClassType, Iterable[DataClassType]], **kwargs)[源代码]¶ 基类:
argparse.ArgumentParser
This subclass of
argparse.ArgumentParser
uses type hints on dataclasses to generate arguments.The class is designed to play well with the native argparse. In particular, you can add more (non-dataclass backed) arguments to the parser after initialization and you'll get the output back after parsing as an additional namespace. Optional: To create sub argument groups use the
_argument_group_name
attribute in the dataclass.-
parse_args_into_dataclasses
(args=None, return_remaining_strings=False, look_for_args_file=True, args_filename=None) → Tuple[DataClass, ...][源代码]¶ Parse command-line args into instances of the specified dataclass types.
This relies on argparse's
ArgumentParser.parse_known_args
. See the doc at: docs.python.org/3.7/library/argparse.html#argparse.ArgumentParser.parse_args- 参数
args -- List of strings to parse. The default is taken from sys.argv. (same as argparse.ArgumentParser)
return_remaining_strings -- If true, also return a list of remaining argument strings.
look_for_args_file -- If true, will look for a ".args" file with the same base name as the entry point script for this process, and will append its potential content to the command line args.
args_filename -- If not None, will uses this file instead of the ".args" file specified in the previous argument.
