fork bitcoin source code, can one use Python based on the source code?

[summer209]

Since Bitcoin was developed with C++, I was wondering if people fork bitcoin source code,  then how to continue the development with other language, such as Java, Python....?

You can't just fork a project in one language and then try to continue its development in another language. That is not how software works.

If you want to develop in another language, then you need to port the project to that other language first. Doing that requires translating from one language to another and that is usually a very difficult task, especially for large projects.

Maybe it is good to mention here that:

1. It is possible to interact with a running Bitcoin client from other languages by using its RPC (Remote Procedure call) interface.
2. If you want to make drastic changes to the way the client ought to work, there are projects like the fairly new Tendermint that do the common work of distributed ledger systems for you, but allow you to write part of the functionality in any programming environment of your choice. (There probably are some strings attached, I do not know a lot about this project at this time.)

you can look at other impl in javascript/golang/java, that would be a better option, if you still insist to use bitcoin core code and use python you can do some nasty tricks like binding and bridges but I would stay from this, it's like substantially more complexity, and software is already complex.
