check if a key exists in a bucket in s3 using boto3

Question

I would like to know if a key exists in boto3. I can loop the bucket contents and check the key if it matches.

But that seems longer and an overkill. Boto3 official

Answer 1

Just following the thread, can someone conclude which one is the most efficient way to check if an object exists in S3?

I think head_object might win as it just checks the metadata which is lighter than the actual object itself
