我已将@Anant的答案添加到我的库中。现在，您可以轻松运行控制台，只需

 ！pip从kora导入控制台安装kora 
 
 console.start（）＃然后点击链接
  

I know that I can call !ls to issue ls command to shell.

But I want features like history or tab-completion.

Is it possible to do so in Google Colab?

解决方案

You can use jQuery Terminal Emulator backed with google.colab.kernel.invokeFunction

Here's an example notebook.

The key part is here, where you back it with shell function.

def shell(command):
  return JSON([getoutput(command)])
output.register_callback('shell', shell)

And here's how you use invokeFunction:

try {
    let res = await google.colab.kernel.invokeFunction('shell', [command])
    let out = res.data['application/json'][0]
    this.echo(new String(out))
} catch(e) {
    this.error(new String(e));
}

Here's a screenshot.

Update (7/2020)

I have taken @Anant's answer and add it into my library. Now you can run console easily with just

!pip install kora
from kora import console
console.start()  # and click link
