evaluate()

bool packaging.markers.Marker.evaluate	(		self,
		dict[str, str] | None	environment = None,
		EvaluateContext	context = "metadata"
	)

Evaluate a marker.

Return the boolean from evaluating the given marker against the
environment. environment is an optional argument to override all or
part of the determined environment. The *context* parameter specifies what
context the markers are being evaluated for, which influences what markers
are considered valid. Acceptable values are "metadata" (for core metadata;
default), "lock_file", and "requirement" (i.e. all other situations).

The environment is determined from the current Python process.
