\subsection{Examples \label{urllib2-examples}}
This example gets the python.org main page and displays the first 100
bytes of it:
\begin{verbatim}
>>> import urllib2
>>> f = urllib2.urlopen('http://www.python.org/')
>>> print f.read(100)
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<?xml-stylesheet href="./css/ht2html
\end{verbatim}
Here we are sending a data-stream to the stdin of a CGI and reading
the data it returns to us:
\begin{verbatim}
>>> import urllib2
>>> req = urllib2.Request(url='https://localhost/cgi-bin/test.cgi',
... data='This data is passed to stdin of the CGI')
>>> f = urllib2.urlopen(req)
>>> print f.read()
Got Data: "This data is passed to stdin of the CGI"
\end{verbatim}
The code for the sample CGI used in the above example is:
\begin{verbatim}
#!/usr/bin/env python
import sys
data = sys.stdin.read()
print 'Content-type: text-plain\n\nGot Data: "%s"' %
data
\end{verbatim}
