and if you're doing this a few times, putting it in a function is even
better.
def tostring(obj):
if obj is None:
return ""
return str(obj)
print tostring(key)
print tostring(foo), tostring(bar)
file.write(tostring(record[1]))
this also makes it easier to tweak things once you realize that not
everything should be passed through str():
def tostring(obj):
if obj is None:
return ""
if isinstance(obj, basestring):
return obj
return str(obj)
