from threading import Thread
import time
 
def quit():
    global tkTop
    tkTop.destroy()

def doSomething():
    print("Do something")

        time.sleep(1)
        varLabel.set(str(count)) 

def runThread():
    varLabel.set("runThread() called")

Python plot sin, cos and tan, using pylab and numpy

import pylab as pl
import numpy as np

X = np.linspace(0, 2*np.pi, 360, endpoint=True)
Y = np.sin(X)
Y2 = np.cos(X)
pl.plot(X, Y)
pl.plot(X, Y2)

pl.show()

numpy and matplotlib are needed in this example.

Install for Python 2:
$ sudo apt-get install python-numpy
$ sudo apt-get install python-matplotlib

Install for Python 3:
$ sudo apt-get install python3-numpy
$ sudo apt-get install python3-matplotlib

Python Tools for Visual Studio

Turn Visual Studio into a powerful Python development environment with Python Tools for Visual Studio.

Python Tools for Visual Studio - free, open-source extension adds all the functionality needed to develop and maintain Python applications in Visual Studio, and deploy to Windows or Linux servers, or to Microsoft Azure.

You can install Python Tools for Visual Studio 2.1 into these versions:

• Visual Studio 2013
• Visual Studio Community 2013
• Visual Studio Express 2013 for Web or for Windows Desktop
• Visual Studio 2012 and 2010

Know more: http://www.visualstudio.com/en-us/explore/python-vs.aspx

This video will help you get up and running with Python in Visual Studio. We will cover installation of PTVS, a Python interpreter, and creating and deploying a project to Azure Websites.

Virtualenv, create isolated Python environments with

virtualenv is a tool to create isolated Python environments.

The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into /usr/lib/python2.7/site-packages (or whatever your platform’s standard location is), it’s easy to end up in a situation where you unintentionally upgrade an application that shouldn’t be upgraded.

Or more generally, what if you want to install an application and leave it be? If an application works, any change in its libraries or the versions of those libraries can break the application.

Also, what if you can’t install packages into the global site-packages directory? For instance, on a shared host.

In all these cases, virtualenv can help you. It creates an environment that has its own installation directories, that doesn’t share libraries with other virtualenv environments (and optionally doesn’t access the globally installed libraries either).

To install globally with pip (if you have pip 1.3 or greater installed globally):

$ [sudo] pip install virtualenv
