drop collection usage

[vihariazure]

my requirement is to delete data inside the collection

for above purpose do i need to use (drop collection vs delete entities )

for drop collection which code do i need to use
from pymilvus import utility
utility.drop_collection("book")

(or)
client.drop_collection(collection_name="book")

If you want to delete all the entities of a collection, it is better to drop the collection.

client.drop_collection is preferred.
