I think it might be a problem with Google Colab or some basic utility package that has been updated, but I can not find a way to solve it.

ANSWER

Answered 2021-Oct-15 at 21:11

Found the problem.
I was installing pandas_profiling, and this package updated pyyaml to version 6.0 which is not compatible with the current way Google Colab imports packages.
So just reverting back to pyyaml version 5.4.1 solved the problem.

For more information check versions of pyyaml here.
See this issue and formal answers in GitHub

##################################################################
For reverting back to pyyaml version 5.4.1 in your code, add the next line at the end of your packages installations:

!pip install pyyaml==5.4.1

It is important to put it at the end of the installation, some of the installations will change the pyyaml version.

QUESTION

ESLint Definition for rule 'import/extensions' was not found

Asked 2022-Feb-14 at 08:36

I'm getting the following two errors on all TypeScript files using ESLint in VS Code:

Definition for rule 'import/extensions' was not found.eslint(import/extensions)
Definition for rule 'import/no-extraneous-dependencies' was not found.eslint(import/no-extraneous-dependencies)

A screenshot from VSC Problems pane:

Note on possible duplicates

There are many similar questions about different modules and even some about the import/extensions, but none of the suggested solutions help. I've tried them all. I also tried every single solution posted in every single thread suggested by Stack Overflow while typing this question.

Here is my .eslintrc.json:

{
  "env": {
      "es2021": true,
      "node": true
  },

    "outDir": "dist",

  }
}

I've tried deleting the whole node_mobules and re-running npm install as well as played with the extends in the .eslintrc.json. If I remove airbnb-typescript/base the error disappears, but I lose the Airbnb style from ESLint. Using airbnb-base instead works, but then ESLint complains about Missing file extension for abc.ts and Unable to resolve path to module abc. I have also multiple time restarted VSC and the ESLint server.

You missed adding this in your eslint.json file.

"plugins": ["import"],

Or,

"extends": ["plugin:import/recommended"]

QUESTION

How did print(*a, a.pop(0)) change?

Asked 2022-Feb-04 at 21:21

This code:

a = [1, 2, 3]
print(*a, a.pop(0))

Python 3.8 prints 2 3 1 (does the pop before unpacking).
Python 3.9 prints 1 2 3 1 (does the pop after unpacking).

What caused the change? I didn't find it in the changelog.

Edit: Not just in function calls but also for example in a list display:

a = [1, 2, 3]
b = [*a, a.pop(0)]
print(b)

Prints [2, 3, 1] vs [1, 2, 3, 1]. And Expression lists says "The expressions are evaluated from left to right" (that's the link to Python 3.8 documentation), so I'd expect the unpacking expression to happen first.

ANSWER

Answered 2022-Feb-04 at 21:21

I suspect this may have been an accident, though I prefer the new behavior.

The new behavior is a consequence of a change to how the bytecode for * arguments works. The change is in the changelog under Python 3.9.0 alpha 3:

bpo-39320: Replace four complex bytecodes for building sequences with three simpler ones.

The following four bytecodes have been removed:

BUILD_LIST_UNPACK

BUILD_TUPLE_UNPACK

BUILD_SET_UNPACK

BUILD_TUPLE_UNPACK_WITH_CALL

The following three bytecodes have been added:

LIST_TO_TUPLE

LIST_EXTEND

SET_UPDATE

On Python 3.8, the bytecode for f(*a, a.pop()) looks like this:

  1           0 LOAD_NAME                0 (f)
              2 LOAD_NAME                1 (a)
              4 LOAD_NAME                1 (a)
              6 LOAD_METHOD              2 (pop)
              8 CALL_METHOD              0
             10 BUILD_TUPLE              1
             12 BUILD_TUPLE_UNPACK_WITH_CALL     2
             14 CALL_FUNCTION_EX         0
             16 RETURN_VALUE

while on 3.9, it looks like this:

  1           0 LOAD_NAME                0 (f)
              2 BUILD_LIST               0
              4 LOAD_NAME                1 (a)
              6 LIST_EXTEND              1
              8 LOAD_NAME                1 (a)
             10 LOAD_METHOD              2 (pop)
             12 CALL_METHOD              0
             14 LIST_APPEND              1
             16 LIST_TO_TUPLE
             18 CALL_FUNCTION_EX         0
             20 RETURN_VALUE

In the old bytecode, the code pushes a and (a.pop(),) onto the stack, then unpacks those two iterables into a tuple. In the new bytecode, the code pushes a list onto the stack, then does l.extend(a) and l.append(a.pop()), then calls tuple(l).

This change has the effect of shifting the unpacking of a to before the pop call, but this doesn't seem to have been deliberate. Looking at bpo-39320, the intent was to simplify the bytecode instructions, not to change the behavior, and the bpo thread has no discussion of behavior changes.

QUESTION

Struggling with TypeScript, React, Eslint and simple Arrow Functions components

Asked 2022-Jan-06 at 21:59

I have been struggling all morning with this issue and couldn't find the solution anywhere. I am new to typescript, and I am trying to set it up properly with Eslint and Prettier to ensure the code is properly formated.

So, the issue I am facing when creating functional components. As per the cheatsheet, I am trying to export a simple component such as:

import React from "react";

type DivProps = {
  text: string;
};

const Div = ({ text }: DivProps): JSX.Element => (<div>{text}</div>)

export default Div;

However, eslint is complaining, saying that "Function component is not a function expression".

When running fix, it will convert my function to an unnamed function:

const Div = function ({ text }: DivProps): JSX.Element {
  return <div>{text}</div>;
};

And then it will complain saying "Unexpected unnamed function.".

Even if I try to refactor the function to:

function Div({ text }: DivProps): JSX.Element {
  return <div>{text}</div>;
};

I still get the same error saying that "Function component is not a function expression".

My .eslintrc.js file is:

module.exports = {
  env: {
    browser: true,
    es2021: true,
  },
  extends: ["airbnb", "plugin:@typescript-eslint/recommended", "prettier"],
  parser: "@typescript-eslint/parser",
  parserOptions: {
    ecmaFeatures: {
      jsx: true,
    },
    ecmaVersion: 12,
    sourceType: "module",
  },
  plugins: ["@typescript-eslint", "react-hooks", "prettier"],
  rules: {
    "react-hooks/rules-of-hooks": "error",
    "prettier/prettier": "error",
    "no-use-before-define": "off",
    "@typescript-eslint/no-use-before-define": ["error"],
    "react/jsx-filename-extension": [
      1,
      {
        extensions: [".tsx"],
      },
    ],
    "import/prefer-default-export": "off",
    "import/extensions": [
      "error",
      "ignorePackages",
      {
        ts: "never",
        tsx: "never",
      },
    ],
  },
  settings: {
    "import/resolver": {
      typescript: {},
    },
  },
};

Appreciate any help on this!

PS: If you see any other thing you would amend/improve in the eslintrc file let me know. As I mentioned, I am new to TypeScript so I am still trying to find out the best options for linting.

Cheers!

Alejandro

ANSWER

Answered 2021-Nov-11 at 16:43

Ok, so I don't know if it is the correct answer, but finally changing the settings in Eslint helped me to change the type of function for Components. I added the following rule to my .eslintrc.js file:

"react/function-component-definition": [
  2,
  {
    namedComponents: "arrow-function",
    unnamedComponents: "arrow-function",
  },
],

With this, eslint will ONLY accept arrow functions for Components, rather than function expressions (as default).
