"alignment" is not a string value, it's an enumeration.  You need to use:

     from reportlab.lib.enums import *
...
     self.alignment = TA_LEFT

One might argue that the library should have presented a more meaningful 
error message in this case, by supplying a default value for dpl and 
checking that the default managed to sneak through.
