The twilio python module and cloud communications platform .

Let you to build apps that communicate with everyone in the world. Voice & Video, Messaging, and Authentication APIs for every application.
First, let's try to install it under Windows 10 operating system:
C:\>cd Python27
C:\Python27>cd Scripts
C:\Python27\Scripts>pip install twilio

Make a account for twilio here.
Now about phone twilio numbers, then programmable phone twilio numbers are a core part of Twilio’s platform, enabling you to receive SMS, MMS, and phone calls.
You can have some problems with SMS sending by country availability.
And one last example:
# /usr/bin/env python
# Download the twilio-python library from
from import Client

# Find these values at
account_sid = "AC61b32be301f49f78f0ab3d69c4d335f6"
auth_token = "c8f37b65755900faa4fe7bbe1f948adb"
client = Client(account_sid, auth_token)

message = client.api.account.messages.create(to="+contry_allow_SMS",
                                             body="Hello python this is a twilio sms test")

Blender 3D - ellipsoid.

This is a simple way to use Blender 3D - version 2.78c with python scripting tool to make one ellipsoid.

The ellipsoid may be parameterized in several ways but I used sin and cos functions:
x = sin(theta) * sin(phi)
y = cos(theta) * sin(phi)
z = cos(phi)

The steps I follow are:
  • make points of ellipsoid - CoordsPoints
  • define a elipsoid vectors 
  • create a new mesh 
  • make rings for faces
  • make a ellipsoid
  • The verts_mesh and verts_mesh_face are used to make faces
  • put all into the Blender 3D scene

import bpy
import bmesh
from math import degrees, radians, sin, cos, tan
from mathutils import Vector

class CoordsPoints:
    def xyz(self):
        theta = self.theta
        phi = self.phi
        x = sin(theta) * sin(phi)
        y = cos(theta) * sin(phi)
        z = cos(phi)
        R = self.R
        return R * Vector((x,y,z))

    def __init__(self, R, theta, phi):
        self.R = R
        self.theta = theta
        self.phi = phi = self.point(theta, phi)

    def __repr__(self):
        return "Coords(%.4f, %.4f)" % (degrees(self.theta),
# define the ellipsoid method.
def ellipsoid(a, b, c):
    def ellipsoid(v):
        x = a * (v.x)
        y = b * (v.y)
        z = c * (v.z)
        return Vector((x, y, z))
    return ellipsoid

# make the ellipsoid bmesh
bm =

# TODO come up with a nicer way to do this.
rings = [[CoordsPoints(1, radians(theta), radians(phi)) 
                 for theta in range (0, 360, 2)]
                 for phi in range(0, 180, 2)]

h = ellipsoid(1.0, 1.0, 1.5)

verts_mesh = [ for p in rings[0]]
for ring in range(1, len(rings)):

    verts_mesh_face = [ for p in rings[ring]]

    faces = [
            verts_mesh[i], verts_mesh_face[i],
            verts_mesh_face[i+1], verts_mesh[i+1]
        for i in range(len(verts_mesh) - 1)
    verts_mesh = verts_mesh_face

# create mesh link it to scene 
mesh ="ellipsoid")
obj ="ellipsoid", mesh)
scene = bpy.context.scene = obj = True
obj.location = scene.cursor_location

The scapy python module - part 001.

Today I will start with scapy python module.
This is a good python module to deal and interact with network packets.
[root@localhost mythcat]# pip install scapy
Collecting scapy

Successfully installed scapy-2.3.3
First test is to test is the echo of Layer 3 ICMP.
Use the super user shell to run this python script:
from scapy.all import *
dstip=raw_input("enter the ip address \n")
p=sr1(ip/icmp,timeout=5, verbose=0)
        print "Layer 3 is up"
        print "Layer 3 status is down"
The next python script will about arp request:
from scapy.all import *
def arp_display(pkt):
    if pkt[ARP].op == 1: 
        return "Request: " + pkt[ARP].psrc + " is asking about " + pkt[ARP].pdst
    if pkt[ARP].op == 2: 
        return "*Response: " + pkt[ARP].hwsrc + " has address " + pkt[ARP].psrc
print sniff(prn=arp_display, filter="arp", store=0, count=10)
This will read the packages from source and destination and show me what ARP traffic my computer is seeing.

How to parse the OPML file.

For example: the Feedly (stylized as feedly) is a news aggregator application for various web browsers and mobile devices can let you to export and import the opml file.

What is XML?
The Extensible Markup Language (XML) is a markup language much like HTML or SGML. This is recommended by the World Wide Web Consortium and available as an open standard.

Today I will show you how to parse the opml file type with python 2.7 version and xml python module.
This is the source script:
from xml.etree import ElementTree
import sys

file_opml = sys.argv[1]
def extract_rss_urls_from_opml(filename):
    urls = []
    with open(filename, 'rt') as f:
        tree = ElementTree.parse(f)
    for node in tree.findall('.//outline'):
        url = node.attrib.get('xmlUrl')
        if url:
    return urls
urls = extract_rss_urls_from_opml(file_opml)
print urls
The result is a list with all your rss links.
