No. You have the full power of the regular expression syntax at your
disposal. It's not about null or anything like that, it's about an
optional piece in the pattern. Using this will work (not the trailing
"?"):
r'^folder/(?P<obj_id>\d+)/(?P<method>\w+)?$'
There are a lot of online tutorials about Python's regular expression
syntax if you're not familiar with that, although the best place to
start is the documentation for the "re" module in Python's own
documentation.
