WebFeb 19, 2015 · At that point, choice of recursive vs. iterative formulation is pretty much a matter of personal and local preference. Some people find recursive code easier to understand. Some people are scared to death of recursion, or don't understand it, or have no clue about tail recursion optimization, and want explicitly iterative code everywhere.

So … WebMay 26, 2024 · The Python interpreter limits the recursion limit so that infinite recursions are avoided. Handling recursion limit –. The “sys” module in Python provides a function called setrecursionlimit () to modify the recursion limit in Python. It takes one parameter, the value of the new recursion limit. By default, this value is usually 10^3.
