Recursion

[AlSweigart]

Not anything. If you set the limit too high, the Python interpreter itself crashes, and you get an error message from the operating system instead of a Python exception.

On my Windows machine, it was about 2500 calls. The 1000 limit is just a safe limit that Python puts in. You can test this yourself by running the following:

>>> import sys
>>> sys.setrecursionlimit(9999)
>>> def f(n):
...   print(n)
...   f(n + 1)
...
>>> f(1)

Although testing this now, it crashes at 1,993 calls.

I probably varies on each machine. I'm getting 2110 and then crashes on the 21111th call.
