Miscellaneous other conversions.

cardinal_pythonlib.convert.base64_64format_decode(s: str) → Optional[bytes][source]

Reverse base64_64format_encode().

Original purpose and notes:

cardinal_pythonlib.convert.base64_64format_encode(v: bytes) → str[source]

Encode in 64'{base64encoded}' format.

Example:

base64_64format_encode(b"hello") == "64'aGVsbG8='"
cardinal_pythonlib.convert.convert_attrs_to_bool(obj: Any, attrs: Iterable[str], default: bool = None) → None[source]

Applies convert_to_bool() to the specified attributes of an object, modifying it in place.

cardinal_pythonlib.convert.convert_attrs_to_int(obj: Any, attrs: Iterable[str], default: int = None) → None[source]

Applies convert_to_int() to the specified attributes of an object, modifying it in place.

cardinal_pythonlib.convert.convert_attrs_to_lowercase(obj: Any, attrs: Iterable[str]) → None[source]

Converts the specified attributes of an object to lower case, modifying the object in place.

cardinal_pythonlib.convert.convert_attrs_to_uppercase(obj: Any, attrs: Iterable[str]) → None[source]

Converts the specified attributes of an object to upper case, modifying the object in place.

cardinal_pythonlib.convert.convert_to_bool(x: Any, default: bool = None) → bool[source]

Transforms its input to a bool (or returns default if x is falsy but not itself a boolean). Accepts various common string versions.

cardinal_pythonlib.convert.convert_to_int(x: Any, default: int = None) → int[source]

Transforms its input into an integer, or returns default.

cardinal_pythonlib.convert.hex_xformat_decode(s: str) → Optional[bytes][source]

Reverse hex_xformat_encode().

The parameter is a hex-encoded BLOB like

"X'CDE7A24B1A9DBA3148BCB7A0B9DA5BB6A424486C'"

Original purpose and notes:

cardinal_pythonlib.convert.hex_xformat_encode(v: bytes) → str[source]

Encode its input in X'{hex}' format.

Example:

special_hex_encode(b"hello") == "X'68656c6c6f'"
