Remove package from results, alternative option

[muellerzr]

Here is a new option to use that is better:

    package_name:str, # The name of a python package
    depth_limit:int=1, # How deep to follow nested dependencies
) -> dict: # A dictionary of {package:version}
    "Recursively grabs dependencies of python package"
    pkgs = pipdeptree.get_installed_distributions(local_only=False, user_only=False)
    tree = pipdeptree.PackageDAG.from_pkgs(pkgs)
    tree = tree.filter([package_name], None)
    curr_depth=0
    def _get_deps(j, dep_dict={}, curr_depth=0):
        if curr_depth > depth_limit: return dep_dict
        if isinstance(j, list):
            for a in j:
                _get_deps(a, dep_dict, curr_depth)
        elif isinstance(j, dict):
            if 'package_name' in j.keys():
                if j['package_name'] not in dep_dict.keys() and j['package_name'] != package_name:
                    dep_dict[j['package_name']] = j['installed_version']
            if 'dependencies' in j.keys():
                curr_depth += 1
                return _get_deps(j['dependencies'], dep_dict, curr_depth)
        return dep_dict
    return _get_deps(ast.literal_eval(pipdeptree.render_json_tree(tree, 4)), {})
