I don't know anything about Delphi; it may use a different calling 
convention than C (unlikely). If that's the case, however, you're out of 
luck unless you can find a Delphi-C or Delphi-Python interface module.

Assuming it uses the C calling convention, you can possibly use the dl 
module:

 import dl
 c=dl.open('/path/to/my/lib.so')
 c.call('myfunc',arg1,arg2)

dl is unfortunately limited to passing integers, strings, and NULL, and to 
returning integers, so it's likely not to be useful for complex data 
structures.
