RouteAnchors.parse_value¶
- RouteAnchors.parse_value(value: Any | List | Dict | Iterable) Any | List | Dict | Iterable¶
Parse a string, mappable (dict, Dict), iterable (list, tuple) to account for units conversion, some basic arithmetic, and design variables. This is the main parsing function of Qiskit Metal.
- Parameters:
value (str) – String to parse or
variable_dict (dict) – dict pointer of variables
- Returns:
Parse value
- Return type:
str, float, list, tuple, or ast eval
- Handled Inputs:
- Strings:
- Strings of numbers, numbers with units; e.g., ‘1’, ‘1nm’, ‘1 um’
Converts to int or float. Some basic arithmetic is possible, see below.
- Strings of variables ‘variable1’.
Variable interpretation will use string method isidentifier ‘variable1’.isidentifier()`
- Dictionaries:
Returns ordered Dict with same key-value mappings, where the values have been subjected to parse_value.
- Itterables(list, tuple, …):
Returns same kind and calls itself parse_value on each element.
- Numbers:
Returns the number as is. Int to int, etc.
- Arithemetic:
Some basic arithmetic can be handled as well, such as ‘-2 * 1e5 nm’ will yield float(-0.2) when the default units are set to mm.
- Default units:
User units can be set in the design. The design will set config.DEFAULT.units
