ak._v2.ak_with_parameter.with_parameter

Defined in awkward._v2.operations.structure.ak_with_parameter on line 8.

ak._v2.ak_with_parameter.with_parameter(array, parameter, value, highlevel=True, behavior=None)
Parameters

  • array – Data convertible into an Awkward Array.

  • parameter (str) – Name of the parameter to set on that array.

  • value (JSON) – Value of the parameter to set on that array.

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

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

This function returns a new array with a parameter set on the outermost node of its ak.Array.layout.

Note that a “new array” is a lightweight shallow copy, not a duplication of large data buffers.

You can also remove a single parameter with this function, since setting a parameter to None is equivalent to removing it.
