Cross Sectoral Standard Set

This part of the project documentation focuses on an information-oriented approach. Use it as a reference for the technical implementation of the pact_methodology project code.

CrossSectoralStandardSet

CrossSectoralStandardSet is a set of CrossSectoralStandard values.

This class provides methods to add, remove, and check for the presence of standards within the set.

Examples:

Creating a set of standards:

>>> standards_set = CrossSectoralStandardSet()
>>> standards_set.add(CrossSectoralStandard.GHG_PROTOCOL)
>>> standards_set.add(CrossSectoralStandard.ISO_14067)
>>> print(standards_set)
{'GHG Protocol Product standard', 'ISO Standard 14067'}

Checking for the presence of a standard:

>>> CrossSectoralStandard.ISO_14044 in standards_set
False

Removing a standard:

>>> standards_set.remove(CrossSectoralStandard.GHG_PROTOCOL)
>>> print(standards_set)
{'ISO Standard 14067'}

Adding multiple standards:

>>> standards_set.add_multiple([CrossSectoralStandard.GHG_PROTOCOL, CrossSectoralStandard.ISO_14044])
>>> print(standards_set)
{'GHG Protocol Product standard', 'ISO Standard 14067', 'ISO Standard 14044'}

String representation of the set:

>>> str(standards_set)
"{'GHG Protocol Product standard', 'ISO Standard 14067', 'ISO Standard 14044'}"

Representation of the set:

>>> repr(standards_set)
"CrossSectoralStandardSet({CrossSectoralStandard.GHG_PROTOCOL, CrossSectoralStandard.ISO_14067, CrossSectoralStandard.ISO_14044})"
