Is there a way of making code like this pass pylint? It's probably
clear from the code, but I'll say it anyway: I'm writing Python code
that'll run on multiple python interpreters, but none of those
interpreters have all 100% of these modules:
try:
# python 3
import dbm.gnu as db_mod
except ImportError:
# python 2
try:
import gdbm_ctypes as db_mod
print('Using gdbm_ctypes')
except ImportError:
try:
import gdbm as db_mod
except ImportError:
# this gets something that's kind of like bsddb on pypy 1.3
via ctypes
import dbm as db_mod
Thanks!

Which error are you talking about ? The code above doesn't raise any
issue with pylint (not with my configuration).
Would it be about unused imports ?
Anyway, another way to write the above code, avoiding that many nested
try blocks (not tested):
_MODULES = ['dbm.gnu', 'gdbm_ctypes', 'gdbm', 'dbm'] # order matters !
for mod in _MODULES:
try:
db_mod = __import__(mod, globals(), locals(), [], -1)
print 'using %s' % mod
break
except ImportError:
continue
else:
raise ImportError('No module among %s can be imported' % _MODULES)
That could fix your pylint issue in the meantime.
