Python Forum

There's any website that I can find a database to test my codes ?
Ans the same question, there's any website where I can find API's ?

Very vague. Please elaborate.
What kind of DBMS, data, etc.
What does your code look like?

If you want a way to easily spin up a database locally, look at using Docker. But yes, the question really is too vague as it stands.

What do you mean by API here? Do you mean, e.g. HTTP APIs? Do you mean Python APIs (i.e. libraries) for doing a particular thing? More details here too please.
