What is the maximum recursion depth in Python, and how to increase it?

Question

I have this tail recursive function here:

def recursive_function(n, sum):
    if n < 1:
        return sum
    else:
        return recursive_function(n-1         


        

Answer 1

We could also use a variation of dynamic programming bottom up approach

def fib_bottom_up(n):

    bottom_up = [None] * (n+1)
    bottom_up[0] = 1
    bottom_up[1] = 1

    for i in range(2, n+1):
        bottom_up[i] = bottom_up[i-1] + bottom_up[i-2]

    return bottom_up[n]

print(fib_bottom_up(20000))
