在Python中，你可以使用以下代码将给定的JavaScript代码转换为Python代码：

def lisp(arr):
    stack = []
    opers = []
    i = 0
    while i < len(arr):
        if arr[i] == ")":
            fragment = stack[opers.pop():]
            fragment.pop(0)  # 把截取出来的片段的头部"("去掉
            op, p1, p2 = "".join(fragment).split(" ")
            res = operate(op, int(p1), int(p2))
            if res == "error":
                return "error"
            stack.extend(str(res))
        else:
            if arr[i] == "(":
                opers.append(len(stack))
            stack.append(arr[i])
        i += 1
    return "".join(stack)


def operate(op, p1, p2):
    if op == "add":
        return p1 + p2
    elif op == "sub":
        return p1 - p2
    elif op == "mul":
        return p1 * p2
    elif op == "div":
        return "error" if p2 == 0 else p1 // p2


line = input()
arr = list(line)
print(lisp(arr))

这是将给定的JavaScript代码转换为等效的Python代码的过程。请注意，这只是一个简单的转换，可能需要根据实际情况进行修改和优化。
