Choice of language for the task: Python vs Delphi?

Question

Python

Hello.
It may seem strange why exactly python and delphi, but I will order the work for freelance, and I understand only in these languages.
I have a postgresql database, I need to create a client that will accept requests in json format, for example, perform actions with the database, and return the result in json.
Basic requirements:
up to 1000 requests will simultaneously access this "pad", the program will have to process requests simultaneously, without creating a queue,
the program will have to spin 24/7 and work and receive requests through an external IP address and the port
will work on windows server / 7 or in the future on hosting
I look towards python because personally it is easier for me to solve the same tasks in python (automation of routine work). And how are they in terms of working with the database, network, json? And the most important thing is that requests from clients are processed simultaneously, will the database allow?
Sorry if I didn't express myself clearly, I write as I know)

And how are they in terms of working with the database, network, json?
