我知道对于 jupyter notebooks 和 jupyter lab，有可用的代码格式化程序扩展，例如nb_black或blackcellmagic. 但是，当我安装它们时，它似乎不适用于 google colab。

您知道 colab 中是否有任何本机选项或格式化代码的扩展程序（符合 pep8）？

I am trying to check in JavaScript if a value from a json is an empty list or not. I tried obviously json.bundleProductSummaries != []. This doesn't work, however this works:

JSON.stringify(json.bundleProductSummaries) != JSON.stringify([])

My json :

  {
    "bundleProductSummaries": [

    ]
  }

My code :

fs = require('fs')
body = fs.readFileSync('./json.txt',{encoding : 'utf-8'})
// ---- Parsing de body ----
let json = JSON.parse(body);
let colored = null;

if(json.bundleProductSummaries != []){
    json = json.bundleProductSummaries[0];
}

Thank you for your future answers …
