Porting to Py3K, I modified a function like the followin, using a trick for it working in Py2.x .
def __iter__(self):
if self == _mpi.INFO_NULL:
return
try: range = xrange
except: pass
nkeys = _mpi.info_get_nkeys(self)
for nthkey in range(nkeys):
yield _mpi.info_get_nthkey(self, nthkey)However, I've got in my unittests (running with py3k)
ERROR: testPyMethods (main.TestInfo)
Traceback (most recent call last): File "tests/unittest/test_info.py", line 123, in testPyMethods for key in INFO: File "/u/dalcinl/lib/python/mpi4py/MPI.py", line 937, in iter for nthkey in range(nkeys): UnboundLocalError: local variable 'range' referenced before assignment
I am not completelly sure if this is expected (it is, regarding implementation, but perhaps not regarding Python as a language), so I post this for your consideration.
