+# Getting function and data names
+
+The best way I've found to get additional API info is to set a breakpoint in your code and then use auto-complete to see what is available. Set a breakpoint:
+```
+for lib in tech.getDB().getLibs():
+    for master in lib.getMasters():
+        print(master.getName())
+        for mterm in master.getMTerms():
+            print(" ", mterm.getName())
+            breakpoint()
+```
+and run your script:
+```

+At the debug prompt, you can use the "p" command like this and press tab or indent twice to autocomplete:
+```
+(Pdb) p mterm.get
+mterm.getBBox                 mterm.getDiffArea             mterm.getMPins                mterm.getName                 mterm.getSigType

+mterm.getDefaultAntennaModel  mterm.getIoType               mterm.getMaster               mterm.getShape
+(Pdb) p mterm.get
+```
+Note that it doesn't do it unless you print. So this does not work:
+```
+(Pdb) mterm.get
+```
