Part II: Beginnings

So, let's say we're new to Python.

Let's get started!

!SLIDE

Step 1: Pick a Release.

Pick carefully.

Step 2: Install Python.

Decisions, decisions.

• Download installer from python.org?
• 32bit or 64bit?
• Build from source?
• If so, Unix or framework build?

Step 3: Profit!

Let's play around. Maybe play with the GitHub API?

!SLIDE small code execute

Ruby.

@@@ ruby
require 'net/http'
require 'uri'

uri = URI.parse('https://api.github.com/user')

http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true

req = Net::HTTP::Get.new(uri.request_uri)
req.basic_auth('username', 'password')

r = http.request(req)

puts r

Python.

@@@ python
import urllib2

gh_url = 'https://api.github.com/user'

req = urllib2.Request(gh_url)

password_manager = urllib2.HTTPPasswordMgrWithDefaultRealm()
password_manager.add_password(None, gh_url, 'user', 'pass')

auth_manager = urllib2.HTTPBasicAuthHandler(password_manager)
opener = urllib2.build_opener(auth_manager)

urllib2.install_opener(opener)

handler = urllib2.urlopen(req)

print handler.read()
