It is settable with sys.setrecursionlimit(). I'm sure there are some
valid reasons to change this but I would look for a different way to
solve my problem first. From the docs:
Set the maximum depth of the Python interpreter stack to limit.
This limit prevents infinite recursion from causing an overflow of the C
stack and crashing Python.
The highest possible limit is platform-dependent. A user may need
to set the limit higher when she has a program that requires deep
recursion and a platform that supports a higher limit. This should be
done with care, because a too-high limit can lead to a crash.
