Just set it yourself:

>>> import sys
>>> sys.tracebacklimit
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'tracebacklimit'
>>> sys.tracebacklimit = 3
>>> def bomb(n):
...     if n: bomb(n-1)
...     else: 1/0
...
>>> bomb(100)
Traceback (most recent call last):
  File "<stdin>", line 2, in bomb
  File "<stdin>", line 2, in bomb
  File "<stdin>", line 3, in bomb
ZeroDivisionError: integer division or modulo by zero
