 *The '''setUp def''' may require changes to parameters in ''self.selenium = selenium( )'', which is the call that launches the browser. The 3rd parameter is the browser type. The 4th parameter is the base URL when starting the script. For more information see the Selenium RC doc [http://seleniumhq.org/docs/05_selenium_rc.html#starting-the-browser Starting the Browser].<br>
 *Comments on how specific IDE commands are converted to Python can be found below.

+==== Method B - Build a Python script from scratch.  ====
+The [http://docs.python.org/library/unittest.html Python unit testing framework] is the foundation of the tests.
+*The Python documentation has a [http://docs.python.org/library/unittest.html#basic-example basic example] that demonstrates its usage.
+*Selenium org's RC documentation has an example of a [http://seleniumhq.org/docs/05_selenium_rc.html#python Python script], which is the same structure created by the IDE exporter to Python.
+The Python unit testing framework is separate from the Selenium class which interacts with the browser.
+*The Python code [http://seleniumhq.org/docs/05_selenium_rc.html#starting-the-browser here] are the commands that create the selenium instance and start the browser.
-==== Method B - Build a Python script from scratch.  ====
+*The Python Selenium class documentation is on the client in the RC directory at selenium-remote-control-1.0.1\selenium-python-client-driver-1.0.1\doc\index.html. Generally every Selenium IDE command has similarly named command in Python, although there are exceptions as noted in the next point.
+*The Selenium IDE can generate Python code for individual SIDE commands by exporting a "script" to Python that contains only one or a few commands. The exporter does not require a fully operational script. An single SIDE command may be translated to one or more Python functions. For example, the verifyXYZ IDE commands are generally translated to a get_xyz( ) passed to an assertion function.
-Selenium org's RC documentation contains an example of a [http://seleniumhq.org/docs/05_selenium_rc.html#python script in Python] which uses the [http://docs.python.org/library/unittest.html Python unit testing framework] and includes the call that [http://seleniumhq.org/docs/05_selenium_rc.html#starting-the-browser starts the browser]. It uses the same structure created by the IDE exporter.

 *'''Indent the body of the script.&nbsp; '''A code block in Python is defined by indention rather than delimiters such as {&nbsp;}.&nbsp; While the exporter correctly indents the Python testing functions that drive the script, most of the converted IDE commands are not.&nbsp; Those statements need to be indented to the same level as the sel = self.selenium statement. &nbsp;Note that indention is in spaces and not tabs.
