Delete all keys from Redis matching a regular expression

redis-delallbykey

# All credit: http://stackoverflow.com/questions/4006324/how-to-atomically-delete-keys-matching-a-pattern-with-redis
redis-cli [options] KEYS "prefix:*" | xargs redis-cli [options] DEL

How do I achieve the same using the redis pypi package ? Right now I'm using r.delete(*r.keys("someKey_*"))
