Filter CodeLists by any attribute about nomenclature HOT 4 CLOSED

Well, I'd rather follow the pyam filter() signature

class CodeList:

    def filter(self, **kwargs) -> CodeList:
        keep = np.ones(len(self), dtype=bool)
        for attribute, value in kwargs:
            keep = np.logical_and(keep, [code.attribute == value for code in self])
            # return a new CodeList(keep)

This would also be compatible with the existing signature (if a user wrote filter(hierarchy="common"), not filter("common")).

from nomenclature.

I guess the interface for this would look something like this then:

class CodeList:

    def filter(self, attribute, value) -> CodeList:
        matched = [code.attribute == value for code in self]
        # return a new CodeList(matched)

The above example wouldn't work exactly like this but is this what you had in mind @danielhuppmann?

Ok, good point, that is cleaner and more powerful.
