Nested arguments parser
Project description
nestargs
nestargs is a Python library that defines nested program arguments. It is based on argparse.
Installation
pip install nestargs
Basic usage
Define program arguments in the same way as argparse. A nested structure can be represented by putting a dot in the program argument name.
import nestargs
parser = nestargs.NestedArgumentParser()
parser.add_argument("--apple.n", type=int)
parser.add_argument("--apple.price", type=float)
parser.add_argument("--banana.n", type=int)
parser.add_argument("--banana.price", type=float)
args = parser.parse_args(
["--apple.n=2", "--apple.price=1.5", "--banana.n=3", "--banana.price=3.5"]
)
# => NestedNamespace(apple=NestedNamespace(n=2, price=1.5), banana=NestedNamespace(n=3, price=3.5))
Let's take out only the program argument apple.
args.apple
# => NestedNamespace(n=2, price=1.5)
You can also get each value.
args.apple.price
# => 1.5
If you want a dictionary format, you can get it this way.
vars(args.apple)
# => {'n': 2, 'price': 1.5}
