Displaying Calculation Output of Python on Web (customizing)

After success displaying output using python based web, it's normal if we want to display the value of function with a range of variable.

The code below will create web page hosted by Python 2.7 BaseHttpServer module. The page contains list of value of function sin(x)+x**2 at -7<x<7

from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
import sys,parser
from math import *
import numpy as np

class Handler(BaseHTTPRequestHandler):
    def do_GET(self):
        n=10
        x1=-7
        x2=7
        y = 'sin(x)+x**2'
        z = parser.expr(y).compile()
        
        self.send_response(200)
        self.send_header("Content-type", "text/html")
        self.end_headers()
        
        self.wfile.write("")
        self.wfile.write("")
        self.wfile.write("Hi Folks, Aravir here
")
        self.wfile.write("
")
        for i in (range(x1,x2)):
            x=i
            self.wfile.write("The value of ")
            self.wfile.write(y )
            self.wfile.write(" on x = " )
            self.wfile.write(x)
            self.wfile.write(" is " )
            self.wfile.write(eval(z) )
            self.wfile.write("
")
        
        self.wfile.write("")

if __name__=="__main__":
    try:
        server = HTTPServer(("", 8080), Handler)
        server.serve_forever()
    except KeyboardInterrupt:
        server.socket.close()
