Welcome to Introduction to Python Programming

If you are unable or uncomfortable with installing programs to your computer you can use the following web-site. It will be fully functional for this bootcamp but will not provide some useful shortcuts.

• http://www.codeskulptor.org/

OSX / Linux

• Python is already installed -- =)

• Install easy_install

import unittest

class TestStringMethods(unittest.TestCase):

    def test_upper(self):
        self.assertEqual('foo'.upper(), 'FOO')

    def test_isupper(self):

This section will continue from our Davinci Django project.

First we'll update our existing models to include additional fields.

Open hello_world/models.py and add 2 fields to StuffToRate

ex:

	color = models.CharField(max_length=100, default='Green')
	description = models.TextField()

In Terminal run the following commands

    virtualenv  VIRTUALENV_NAME
    cd VIRTUALENV_NAME
    source bin/activate
    pip install django ipython
