Json dictionnary on Redis

[katsu707]

Hi everyone, I'm a complete beginner and here's my issue:

I have Flask as a webserver, Redis is counting the number of hits on the root. I added a arg "name".
I want to store and return a different count that I wish to link to the "name" var.
I got some help and they advised to use a JSON dictionnary. I'm struggling with the implementation. My code looks like this:

from flask import Flask
from redis import Redis
import json

app = Flask(__name__)
redis = Redis(host='redis', port=6379)

@app.route('/')
@app.route('/<name>')
def hello(name):
    counts = json.loads(redis.get('hits'),('{}'))
    try:
         counts[name] += 1
    except KeyError:
         counts[name] = 1
    redis.set('hits', json.dumps(counts))
    return 'Hello {} I have been seen {} times.\n'.format(name,counts[name])

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8000, debug=True)

I keep getting this error and I don't know why...

Error:
 File "/app/app3.py", line 11, in hello
    counts = json.loads(redis.get('hits'),('{}'))
TypeError: loads() takes 1 positional argument but 2 were given

Thanks a lot!
K.
