format_as_list

lsst.ts.standardscripts.format_as_list(value, recurrences)

Reformat single instance of the attribute value as a list with a specified number of recurrences .

Configurations often allow a single value for an attribute to be passed that needs to be replicated as a list. This occurs when the (YAML) type is specified as an array but a user provides a single value (as a float/int/string etc). For example, an instrument setup for 5 different exposure times may only be given a single value for filter. However, often the single filter value needs to be reformatted of a list of length 5.

This function returns the input as a list, with the desired of recurrences.

Parameters:

value: `str, float, int, boolean`

A single element of any type. Must not be a list.

recurrences: `int`

An integer specifying the number of occurrences and length of the returned list

Returns:

value_as_list: list

A list of length recurrences, where all elements are the input parameter value
