Methods

__init__(value_type=DataType(string), list_size=-1)

check(pandera_dtype, data_container=None)

Check that pandera DataType are equivalent.

Parameters:

• pandera_dtype (DataType) – Expected DataType.

• data_container (Union[Series, DataFrame, None]) – Data container, used by data types that require the actual data for validation.

Return type:

Union[bool, Iterable[bool]]

Returns:

boolean scalar or iterable of boolean scalars, indicating which elements passed the check.

coerce(data_container)

Pure coerce without catching exceptions.

Return type:

Union[Series, DataFrame]

coerce_value(value)

Coerce a value to a particular type.

Return type:

Any

classmethod from_parametrized_dtype(pyarrow_dtype)

try_coerce(data_container)

Coerce data container to the data type, raises a ParserError if the coercion fails :raises: ParserError: if coercion fails

Return type:

Union[Series, DataFrame]

__call__(data_container)

Coerce data container to the data type.
