For this, we use WingIDE, a commercial IDE for Python.

When you mean a debugger that can set breakpoints in any thread,
analyse the state of any thread etc, then this is unlikely.

  Python maintains the debugging hook in a thread specific data structure.
  The available API functions can only access the debugging hook
  in the own thread but not in a foreign thread.

  This implies that unless the start of a thread is customized
  (such that the debugging hook is immediately set on thread start)
  it is very difficult to debug a foreign thread (without
  a specialized C extension using internal implementation details of
  Pythons thread implementation).
