编写一段输出斐波那切数列的Python代码

以下是输出斐波那契数列的Python代码：

def fibonacci(n):
    if n <= 0:
        return []
    elif n == 1:
        return [0]
    elif n == 2:
        return [0, 1]
    else:
        fib = [0, 1]
        for i in range(2, n):
            fib.append(fib[i-1] + fib[i-2])
        return fib

print(fibonacci(10))

输出结果为：[0, 1, 1, 2, 3, 5, 8, 13, 21, 34]
