[Jython-users] problems starting threads

[Russo, T. <to...@st...>]

Hi,

When I run the following:

<file name="demo.py">
import thread

thread.start_new_thread(lambda x,y:(x,y), (1,2))        # succeeds
thread.start_new_thread(lambda x:x, (1))                  # fails
</file>

I get:

<output>
Traceback (innermost last):
  File "demo.py", line 4, in ?
TypeError: start_new_thread(): 2nd arg can't be coerced to
org.python.core.PyTuple
</output>

Is there some reason I should be able to use a function of two arguments
when starting a thread, but not a function of one argument?  Does jython not
recognize (1) as a tuple in this case?

thanks
