Prefixstripping
Prefixstripping is the operation of removing a specified leading sequence of characters, or prefix, from strings or tokens. It is widely used in data preprocessing, parsing, and normalization to reduce variability and prepare data for comparison or processing. The operation typically checks whether the input begins with a given prefix and, if so, returns the remainder; if not, the original input is returned. It can be applied case-sensitively or case-insensitively and must handle empty inputs, empty prefixes, and Unicode strings.
Implementation notes: In many languages there are built-in functions. In Python 3.9 and later, removeprefix(prefix) removes
Common applications: normalizing identifiers that share a common prefix, preparing user input for tokenization, stripping protocol
