<div>

</div>
<div>
<p class="MsoNormal">1. The IronPython console is a REPL, so don't be afraid of writing exploratory code fragments to inspect various variables and objects. You don't have to get the script code correct the first time round. Unfortunately, as I myself just
discovered, there's an annoying bug where you can't copy the current console contents to the clipboard (to paste into a reusable script) so building reusable scripts is a bit of a pain atm. This is a known issue that I'll look at a later time: <a href="https://github.com/jumpinjackie/mapguide-maestro/issues/152">https://github.com/jumpinjackie/mapguide-maestro/issues/152</a><o:p></o:p></p>

<p class="MsoNormal">2. This decade-old blog post of mine has some useful tips around the IronPython console: <a href="https://themapguyde.blogspot.com/2013/08/maestro-ironpython-console-tips-and.html">https://themapguyde.blogspot.com/2013/08/maestro-ironpython-console-tips-and.html</a><o:p></o:p></p>

</div>
<div>
<p class="MsoNormal">3. The objects you are interacting with are part of the Maestro .net API exposed to the IronPython engine, so it's useful to always have the .net API reference on hand when you want to know what a particular class or interface is: <a href="https://jumpinjackie.github.io/mapguide-maestro/api/">https://jumpinjackie.github.io/mapguide-maestro/api/</a><o:p></o:p></p>
