Python

Zentra is building with CPython version 3.10 under a standard Ubuntu 22.04 LTS version.

A Windows WSL environment is recommend, and https://canonical.com/multipass is recommend when WSL is not available (for Windows and Mac).

For the playground, CPython 3.10 is recommend:

• Standard python 3.10.x https://www.python.org/downloads/release/python-31018/

• Windows Store https://apps.microsoft.com/detail/9pjpw5ldxlz5

• UV to manage multi versions in local https://github.com/astral-sh/uv

To start the development, it is briefly to create a new function in python, which will make changes to the current global state from a block transaction. If you are not familiar with State Machine concept, please check the next paragraph for a simple tutorial of State Machine Concept.

def a_new_function(info, args):
    pass

The parameters are fixed: info will provide the blockchain related information and args will contains the arguments you passed for the function invoke to Zentra.

By using python, we allow developers to use almost all the native python syntax except the import and class keywords. Most of the built-in function are allowed, but we do not provide open and other risk functions. The python code would be convert into python bytecode, thus most of dynamic feature would be kept, like infinite integer and list, dict, set, tuple.
