RecursionError: maximum recursion depth exceeded while calling a Python object

using python 3.11.3

sys.setrecursionlimit(num) crashes windows before completing a block transformation

Same problem, solved by modifying recursive function merkle_root to while-loop

def merkle_root(lst):
    sha256d = lambda x: hashlib.sha256(hashlib.sha256(x).digest()).digest()
    hash_pair = lambda x, y: sha256d(x[::-1] + y[::-1])[::-1]
    while len(lst) != 1:
        if len(lst) % 2 == 1:
            lst.append(lst[-1])
        lst = [hash_pair(x,y) for x, y in zip(*[iter(lst)]*2)]
    return lst[0]

Now it is a dead loop...

I think it is because the dat fil corrupted or you trying to parse any altcoin without some tricks
