Increment value of a hash field in Redis using Python

Question

I have created a hash in redis in python as follows:

r.hmset('list:123', {'name': 'john', 'count': 5})

How can I increment the value of count for the key list:123?

hash = 'list:123'
key = 'count'
n = 1

r.hincrby(hash, key, n)

I think the point is not to overwrite what's already there. More of a read+write op, like hincrby.
