            A mapping of logical names to lockfile paths used in your project.

            Many organizations only need a single resolve for their whole project, which is
            a good default and often the simplest thing to do. However, you may need multiple
            resolves, such as if you use two conflicting versions of a requirement in
            your repository.

            If you only need a single resolve, run `{bin_name()} generate-lockfiles` to
            generate the lockfile.

            If you need multiple resolves:

              1. Via this option, define multiple resolve names and their lockfile paths.\
                The names should be meaningful to your repository, such as `data-science` or\
                `pants-plugins`.
              2. Set the default with `[python].default_resolve`.
              3. Update your `python_requirement` targets with the `resolve` field to declare which\
                resolve they should be available in. They default to `[python].default_resolve`,\
                so you only need to update targets that you want in non-default resolves.\
                (Often you'll set this via the `python_requirements` or `poetry_requirements`\
                target generators)
              4. Run `{bin_name()} generate-lockfiles` to generate the lockfiles. If the results\
                aren't what you'd expect, adjust the prior step.
              5. Update any targets like `python_source` / `python_sources`,\
                `python_test` / `python_tests`, and `pex_binary` which need to set a non-default\
                resolve with the `resolve` field.

            If a target can work with multiple resolves, you can either use the `parametrize`
            mechanism or manually create a distinct target per resolve. See {doc_url("docs/using-pants/key-concepts/targets-and-build-files")}
            for information about `parametrize`.

            For example:

                python_sources(
                    resolve=parametrize("data-science", "web-app"),
                )

            certain file extension or location.

            The style of lock to generate. Valid values are 'strict', 'sources', or 'universal'
            (additional styles may be supported in future PEX versions).

            The 'strict' style generates a lock file that contains exactly the
            distributions that would be used in a local PEX build. If an sdist would be used, the sdist is included, but if a
            wheel would be used, an accompanying sdist will not be included. The 'sources' style includes locks containing both
            wheels and the associated sdists when available. The 'universal' style generates a universal lock for all possible
            target interpreters and platforms, although the scope can be constrained via `[python].resolves_to_interpreter_constraints`. Of
            the three lock styles, only 'strict' can give you full confidence in the lock since it includes exactly the artifacts
            that are included in the local PEX you'll build to test the lock result with before checking in the lock. With the
            other two styles you lock un-vetted artifacts in addition to the 'strict' ones; so, even though you can be sure to
            reproducibly resolve those same un-vetted artifacts in the future, they're still un-vetted and could be innocently or
            maliciously different from the 'strict' artifacts you can locally vet before committing the lock to version control.
            The effects of the differences could range from failing a resolve using the lock when the un-vetted artifacts have
            different dependencies from their sibling artifacts, to your application crashing due to different code in the sibling
            artifacts to being compromised by differing code in the sibling artifacts. So, although the more permissive lock
            styles will allow the lock to work on a wider range of machines /are apparently more convenient, the convenience comes
            with a potential price and using these styles should be considered carefully.

            Expects a dictionary of resolve names from `[python].resolves` to style values.
            If a resolve is not set in the dictionary, it will default to 'universal'.

            Examples:
            - `{{'data-science': 'strict', 'web-app': 'universal'}}` - use strict style for data-science resolve, universal for web-app
            - `{{'python-default': 'sources'}}` - use sources style for the default resolve

            You can use the key `{RESOLVE_OPTION_KEY__DEFAULT}` to set a default value for all
            resolves.

            Complete platforms allow you to create lockfiles for specific target platforms

            universal platforms. This is particularly useful for cross-platform builds or

            You can give a list of multiple complete platforms to create a multiplatform lockfile,

            For example:
            `{{'python-default': ['3rdparty/platforms:linux_aarch64', '3rdparty/platforms:macos_arm64']}}`.

            You can use the key `{RESOLVE_OPTION_KEY__DEFAULT}` to set a default value for all
