Python web application with Nginx

Let us create a simple API in Python and serving it using Nginx.

In this example we will use Debian 9 as a distro for the server.

The code

Alright, let's write some code.
We will create an API that will serve an array of fruits.

Let's create a __main__.py file:

#include <iostream>


template <typename T>
T perform_operation(const T& left, std::string op, const T& right) {
    if (op == "+")
        return left + right;
    if (op == "-")
        return left - right;
}

question_state=0

function ask() {
    read -p "$1" -n 1 -r
    echo
    if [[ $REPLY =~ ^[Yy]$ ]]
    then
        question_state=1
    fi   
}

hello_cpp_cout:

#include <iostream>
int main()
{
    std::cout << "Hello world" << std::endl;
    return 0;
}
