Overview ======== This module supports the following requirements: - options are referenced using keys in dot.notation, e.g. "x.y.option - z". - keys are case-insensitive. - functions should accept partial/regex keys, when unambiguous. - options can be registered by modules at import time. - options can be registered at init-time (via core.config_init) - options have a default value, and (optionally) a description and validation function associated with them. - options can be deprecated, in which case referencing them should produce a warning. - deprecated options can optionally be rerouted to a replacement so that accessing a deprecated option reroutes to a differently named option. - options can be reset to their default value. - all option can be reset to their default value at once. - all options in a certain sub - namespace can be reset at once. - the user can set / get / reset or ask for the description of an option. - a developer can register and mark an option as deprecated. - you can register a callback to be invoked when the option value is set or reset. Changing the stored value is considered misuse, but is not verboten. Implementation ============== - Data is stored using nested dictionaries, and should be accessed through the provided API. - "Registered options" and "Deprecated options" have metadata associated with them, which are stored in auxiliary dictionaries keyed on the fully-qualified key, e.g. "x.y.z.option". - the config_init module is imported by the package's __init__.py file. placing any register_option() calls there will ensure those options are available as soon as pandas is loaded. If you use register_option in a module, it will only be available after that module is imported, which you should be aware of. - `config_prefix` is a context_manager (for use with the `with` keyword) which can save developers some typing, see the docstring. ) annotations)ContextDecoratorcontextmanagerN) TYPE_CHECKINGAnyCallableGeneric NamedTuplecast)FT)find_stack_level) GeneratorIterablec@s.eZdZUded<ded<ded<ded<dS)DeprecatedOptionstrkey str | Nonemsgrkey removal_verN__name__ __module__ __qualname____annotations__rrT/var/www/html/laksyashrimp/venv/lib/python3.9/site-packages/pandas/_config/config.pyrQs rc@s6eZdZUded<ded<ded<ded<ded <d S) RegisteredOptionrrobjectdefvaldocCallable[[object], Any] | None validatorCallable[[str], Any] | NonecbNrrrrrrXs rzdict[str, DeprecatedOption]_deprecated_optionszdict[str, RegisteredOption]_registered_optionsdict[str, Any]_global_configall list[str]_reserved_keysc@seZdZdZdS) OptionErrorz Exception raised for pandas.options.

All matching keys will have their description displayed. _print_desc : bool, default True If True (default) the description(s) will be printed to stdout. Otherwise, the description(s) will be returned as a unicode string (for testing).
