Python URL Handling

In case you're wondering "How the heck does Python handle headers and data under 3.2.2?", here's an example that works using IDLE and Python 3.2.2 installed on a 64-bit Windows 7 machine.

import re
import urllib.request
url = "http://www.philadelphia-reflections.com"

uf = urllib.request.urlopen(url)

# header information
print('--- headers ---')
info = uf.info()  # headers

#headers = info._headers # a list of all the headers

print('charsets:',info.get_charsets())
print('content_charset:',info.get_content_charset()) 
print('content_type:',info.get_content_type())
print('content_maintype:',info.get_content_maintype())
print('content_subtype:',info.get_content_subtype())
print('default_type:',info.get_default_type())
print('filename:',info.get_filename())
print('params:',info.get_params())
print('payload:',info.get_payload())

print()
print('--- data ---')

data = uf.read().decode(info.get_content_charset()) # content
print(data[:500])

print()
print('--- image ---')

imageurl = url + "/images/001.JPG"
image = urllib.request.urlretrieve(imageurl, 'python_001.jpg')
print(image)
