<FONT><h3>Summary</h3>
<p>Python's standard distribution is shipped with a rich set of libraries (also known as modules). This chapter introduces you to the practical side of several modules'utilization.</p>
<P>The following items are groups that organize all the modules that are mentioned in this chapter.</P>
<H4>Python Services</H4>
<p>The modules from this group provide access to services related to the interpreter and to Python's environment.</p>
<h4>The String Group</h4>
<P>This group is responsible for many kinds of string services available. Its modules provide access to several types of string manipulation operations.</P>
<H4>Miscellaneous</H4>
<p>This group handles many functions that are available for all Python versions, such as mathematical operations and randomizing functions.</p>
<h4>Generic Operational System</h4>
<P>This group of services provides interfaces to operating system features that you can use in almost every platform.</P>
<H4>Optional Operational System</H4>
<p>This set of modules implements interfaces to optional operational system features.</p>
<h4>Debugger</h4>
<p>The <tt class="monofont">pdb</tt> module defines an interactive source code debugger for Python programs.</p>
<h4>Profiler</h4>
<p>The <tt ClaSs="monofont">profiler</tt> module is a code execution profiler.</P>
<h4>Internet Protocol and Support</h4>
<p>These are the modules that implement internet protocols and support for related technology.</p>
<H4>Internet Data Handling</h4>
<p>This group covers modules that support encoding and decoding of data handling formats and that are largely used in Internet applications.</p>
<H4>Restricted Execution</H4>
<P>These modules prevent access to critical operations.</P>
<h4>Multimedia</h4>
<p>This group of modules implements algorithms and interfaces that are mainly useful for multimedia applications.</p>
<H4>Cryptographic</H4>
<P>These modules implement various algorithms of cryptographic nature.</P>
<h4>OS Specific (UNIX, SGI IRIX, SUN OS, MS Windows, and Macintosh)</h4>
<p>These groups of modules expose interfaces to features that are specific to the OS environment of each one of them.</p>
<H4>Undocumented Modules</H4>
<P>This group contains the modules that currently don't have any official documentation.</P>
<h4>New Modules in Python 2.0</h4>
<p>These are the new modules that will be part of the next release of Python.</p>
