ak.str.is_numeric

Defined in awkward.operations.str.akstr_is_numeric on line 12.

ak.str.is_numeric(array, *, highlevel=True, behavior=None)

Parameters

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

• 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.

Replaces any string-valued data with True if the string is non-empty and consists only of numeric Unicode characters, False otherwise.

Replaces any bytestring-valued data with True if the string is non-empty and consists only of numeric Unicode characters, False otherwise.

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.utf8_is_numeric or pyarrow.compute.utf8_is_numeric on strings and bytestrings, respectively.

(Arrow’s compute module does not have an ascii_is_numeric.)
