row_hash(row, column='id', algorithm=hashlib.sha256)

Hashes a row (dictionary) using SHA256 and adds the hash as a new column.

Parameters:

Name	Type	Description	Default
row	dict[str, Any]	The dictionary (row) to hash.	required
column	str	The name of the column to store the hash. Defaults to "id".	'id'
algorithm	Callable[[bytes], HASH]	The hashing algorithm to use. Defaults to hashlib.sha256.	sha256

Returns:

Type	Description
dict[str, Any]	The modified row (dictionary) with the SHA256 hash added.
