use python libraries in react native

In this framework, best way to integrate Python Code, machine learning or otherwise is to connect NodeJS app with Python interpreter. This also happens to be complex to implement. This will go something like this

#include <Python.h>


int main(int argc, char *argv[]){
  Py_SetProgramName(argv[0]);  /* optional but recommended */
  Py_Initialize();
  PyRun_SimpleString("from time import time,ctime\n"
                 "print 'Today is',ctime(time())\n");
  Py_Finalize();
  return 0;
}

Below is an example of a class component:

class Header extends React.Component {
  render() {
    return <h2>Hello, I am a header!</h2>;
  }
}

The equivalent of the class component in Python is as follows:

class MyComponent(Component):
   def __init__(self):
   super().__init__()

def render(self):
   return "Hello, I am a heder";

A functional component, like a class component, returns HTML and operates similarly, but functional components can be constructed with significantly less code, are easier to grasp due to their simple syntax, and are favored in this tutorial:

function Header() {
  return <h2>Hello, I am a header!</h2>;
}

Secondly, in HTML, we use strings like the following to define inline styles:

<h1 style="color: hotpink; font-size: 12px">Hello<h1>

However, in JSX, we utilize camel-cased objects:

<h1 style="color" : "hotpink" , "fontSize" : "12px"> Hello </h1>
