WebMay 12, 2024 · A tail call is simply a recursive function call which is the last operation to be performed before returning a value. To be clear, return foo(n – 1) is a tail call, but return foo(n – 1) + 1 is not (since the addition is the last operation). Tail call optimization (TCO) is a way to automatically reduce Python Recursion in recursive functions. WebPython doesn't optimise tail-calls, so no. At least not right now.
