Question

椰子看起来像一种很棒的语言。我看到它支持Jupyter，但是我不确定在尝试将其安装到Google的colab时出了什么问题。

运行!pip install coconut时，安装成功。

但是后来我尝试了第一个椰子“案例研究”。

def factorial(n):
    """Compute n! where n is an integer >= 0."""
    if n `isinstance` int and n >= 0:
        acc = 1
        for x in range(1, n+1):
            acc *= x
        return acc
    else:
        raise TypeError("the argument to factorial must be an integer >= 0")

使用isinstance作为中缀运算符会产生语法错误。

当我将isinstance更改为常规函数并尝试测试用例时，发生了同样的事情：

3 |> factorial |> print

另一个语法错误。

我是否无法正确执行安装步骤，或者Colab不能在Colab上正常工作？

谢谢。

P.S。

!coconut -h

回复适当的帮助信息。

P.P.S

!coconut --jupyter

回复Coconut: Successfully installed Coconut Jupyter kernel.

但是colab仍然像没听说过椰子一样运行

是否可以在colab上运行椰子
