ak.str.match_like

Defined in awkward.operations.str.akstr_match_like on line 13.

ak.str.match_like(array, pattern, *, ignore_case=False, highlevel=True, behavior=None, attrs=None)

Parameters:

• array – Array-like data (anything ak.to_layout recognizes).

• pattern (str or bytes) – SQL-style LIKE pattern to match against strings in array.

• ignore_case (bool) – If True, perform a case-insensitive match; otherwise, the match is case-sensitive.

• highlevel (bool) – If True, return an ak.Array; otherwise, return a low-level ak.contents.Content subclass.

• behavior (None or dict) – Custom ak.behavior for the output array, if high-level.

• attrs (None or dict) – Custom attributes for the output array, if high-level.

For each string in the array, determine whether it matches the given SQL-style LIKE pattern, which obeys the following rules:

• ‘%’ matches any number of characters.

• ‘_’ matches exactly one character.

• Any other character matches itself.

• To match a literal ‘%’, ‘_’, or “’”, the character must be preceded with a backslash.

Note: this function does not raise an error if the array does not contain any string or bytestring data.

Requires the pyarrow library and calls pyarrow.compute.match_like.
