Yes. You do it like this:
def method(**kwargs):
print kwargs
keywords = {'keyword1': 'foo', 'keyword2': 'bar'}
method(keyword1='foo', keyword2='bar')
method(**keywords)
Running this in Python confirms these produce identical results:
{'keyword2': 'bar', 'keyword1': 'foo'}
{'keyword2': 'bar', 'keyword1': 'foo'}
