How to detect that Python code is being executed through the debugger?

Question

Is there a simple way to detect, within Python code, that this code is being executed through the Python debugger?

I have a small Python application that uses Java c

A solution working with Python 2.4 (it should work with any version superior to 2.1) and Pydev:

import inspect

def isdebugging():
  for frame in inspect.stack():
    if frame[1].endswith("pydevd.py"):
      return True
  return False

The same should work with pdb by simply replacing pydevd.py with pdb.py. As do3cc suggested, it tries to find the debugger within the stack of the caller.
