I'm trying to write some code that will load one of three dll depending on the
one available. I've tried the code below, but it doesn't work. The try except
doesn't catch the exception. Is there a way to do this?
try:
self.dll = windll.pvcam64
except:
print "No pvcam64"
try:
self.dll = windll.pvcam32
except:
print "No pvcam32"
try:
self.dll = windll.pvcam
except:
print "No pvcam"
return
else:
print "installed pvcam"
else:
print "installed pvcam32"
else:
print "installed pvcam64"
This works for me:
for name in ("pvcam64", "pvcam32", "pvcam"):
try:
self.dll = getattr(windll, name)
except OSError:
print "No " + name
else:
print "Installed " + name
return
