Utilities for data handling.

is_number_dtype(dtype)[source]#

Check if dtype is number-like.

Parameters:: dtype (str | dtype[Any] | None | type[Any] | _SupportsDType[dtype[Any]] | tuple[Any, int] | tuple[Any, SupportsIndex | Sequence[SupportsIndex]] | list[Any] | _DTypeDict | tuple[Any, Any] | ExtensionDtype) – dtype to check.
Returns:: True if dtype is number-like.
Return type:: bool

to_boolean(s)[source]#

Parse boolean series from string series.

to_integer(s)[source]#

Parse integer series from string series with locale-awareness.

to_float(s)[source]#

Parse float series from string series with locale-awareness.

parse_dtype(s, dtype=None, src_locale=None)[source]#

Parse series to dtype with locale-awareness.

Parameters:

s (Series) – series to convert.
dtype (str | type | dtype[Any] | None | type[Any] | _SupportsDType[dtype[Any]] | tuple[Any, int] | tuple[Any, SupportsIndex | Sequence[SupportsIndex]] | list[Any] | _DTypeDict | tuple[Any, Any]) – dtype to convert to.
src_locale (str | None) – locale to use for conversion.

Returns:

Converted series.

Return type:

Series

gen_id(x, length=10, raw_str=False)[source]#

Generate stable hash for obj (must be known, hashable or composed of such).

Parameters:

x (Any) – Object to hash.
length (int) – Length of the hash.
raw_str (bool) – Whether to use the raw string representation of the object, if it is a string.

Returns:

Hash of the object as string.

Return type:

str
