Python: Get the current value of the recursion limit

Python Basic: Exercise-80 with Solution

Write a Python program to get the current value of the recursion limit.

sys.getrecursionlimit(): Return the current value of the recursion limit, the maximum depth of the Python interpreter stack. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python. It can be set by setrecursionlimit().

Sample Solution:

Python Code:

import sys
print()
print("Current value of the recursion limit:")
print(sys.getrecursionlimit())
print()

Sample Output:

Current value of the recursion limit:

How to change the maximum recursion depth in Python?

sys.setrecursionlimit(limit): 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 they have 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.

Python Code:

import sys
print("Call sys.getrecursionlimit() to get the current recursion limit:")
recursion_limit = sys.getrecursionlimit()
print(recursion_limit)
print("\nCall sys.setrecursionlimit(n) to change the recursion limit to n operations:")
sys.setrecursionlimit(1001)
new_recursion_limit = sys.getrecursionlimit()
print(new_recursion_limit)

Sample Output:

Call sys.getrecursionlimit() to get the current recursion limit:
1000

Call sys.setrecursionlimit(n) to change the recursion limit to n operations:
1001
