Python Tricks Every Developer Should Know

Python is awesome, it’s one of the easiest languages with simple and intuitive syntax but wait, have you ever thought that there might ways to write your python code simpler?

In this tutorial, you’re going to learn a variety of Python tricks that you can use to write your Python code in a more readable and efficient way like a pro.

Let’s get started

Swapping value in Python

Instead of creating a temporary variable to hold the value of the one while swapping, you can do this instead

>>> FirstName = "kalebu"
>>> LastName = "Jordan"
>>> FirstName, LastName = LastName, FirstName 
>>> print(FirstName, LastName)
('Jordan', 'kalebu')

How to Remove all Duplicate Files on your Drive via Python

Today you’re going to learn how to use Python programming in a way that can ultimately save a lot of space on your drive by removing all the duplicates.


In many situations you may find yourself having duplicates files on your disk and but when it comes to tracking and checking them manually it can tedious.

Heres a solution

Instead of tracking throughout your disk to see if there is a duplicate, you can automate the process using coding, by writing a program to recursively track through the disk and remove all the found duplicates and that’s what this article is about.

But How do we do it?

If we were to read the whole file and then compare it to the rest of the files recursively through the given directory it will take a very long time, then how do we do it?

The answer is hashing, with hashing can generate a given string of letters and numbers which act as the identity of a given file and if we find any other file with the same identity we gonna delete it.

There’s a variety of hashing algorithms out there such as

  • md5
  • sha1
  • sha224, sha256, sha384 and sha512

Como Usar Variáveis ​​de Referência De Modelo Em Angular

Neste post você aprenderá a usar variáveis ​​de referência de modelo, muitas vezes conhecidas como “Referências de modelo”, em Angular.

Em Angular, os componentes possuem uma templatepropriedade, que contém elementos e outros componentes. Uma variável de referência de modelo é um recurso que nos permite obter acesso a uma parte de nosso modelo.

Isso pode ser um elemento, componente ou pode ser uma diretiva. As variáveis ​​de referência de modelo são implementadas de maneira inteligente e podem ser usadas de várias maneiras.

A primeira pode ser simplesmente exportar uma referência a um elemento. Aqui podemos anexar a #a an <input>e fornecer um nome de variável (daí a referência do modelo 'variable'):

<input type="text" #coffee>

Você pode pensar nessa sintaxe como uma “exportação”. Estamos exportando uma referência ao elemento.

Isso significa que agora podemos acessar as propriedades dessa variável de referência como se ela fosse retornada para nós por meio de JavaScript simples (pense no que você voltaria usando document.querySelector('input')e é isso que temos aqui):

<input type="text" #coffee>

<p>{{ coffee.value }}</p>

Isso desconectaria uma string vazia coffee.value, pois não temos value. Nossa coffeevariável está nos dando diretamente um HTMLInputElement.

Para vermos o valor enquanto digitamos, precisaríamos introduzir a ngModelDiretiva:

<input type="text" ngModel #coffee>

<p>{{ coffee.value }}</p>

Experimente e digite algo no <input>:

Então aqui está o próximo grande recurso das referências de modelo.

Vamos exportar uma referência para o nosso ngModele mudar o contexto do que #coffeenos retorna.

Ao especificar #coffee, estamos implicitamente deixando o Angular decidir o que exportar, porque não estamos especificando nada além de vincular ao elemento.

Estamos vinculando ngModel, que agora é 'parte' do nosso <input>. Vamos exportá-lo:

<input type="text" ngModel #coffee="ngModel">

<p>Value: {{ coffee.value }}</p>
<p>Pristine: {{ coffee.pristine }}</p>
<p>Touched: {{ coffee.touched }}</p>

Ao passar #coffee="ngModel", estamos vinculando explicitamente uma referência à nossa ngModeldiretiva rastreada.

Não temos mais HTMLInputElement. Temos uma referência a NgControl.

Você pode verificar o código-fonte do NgControl aqui, que estende as classes NgControl e AbstractControlDirective .

Por que estamos olhando para isso? Porque ele mostra todas as propriedades disponíveis para você, e é exatamente por isso que referenciamos não apenas , valuemas pristinee touchedtambém.

Experimente-os abaixo, nossa variável de referência de modelo está espelhando o ngModel:

Podemos aprofundar isso e acessar um template ref dentro de um componente , para que possamos acessar propriedades e métodos de dentro do classe não apenas do template.

Isso é conseguido usando talvez TemplateRefou ElementRefao lado de um @ViewChilddecorador. Leia o artigo acima sobre como fazer isso e um trabalho mais profundo, mas essencialmente se parece com isso:

export class AppComponent {
  @ViewChild('username') input: ElementRef<HTMLInputElement>;

Essa é uma boa introdução às referências de modelo, e espero que dê a você uma compreensão mais profunda de como usá-las, quando e onde. Não apenas isso, mas o que esperar quando você declarar um template ref e como também exportar referências para coisas como diretivas.

Feliz refrão!

Comment Utiliser Les Variables De Référence De Modèle Dans Angular

Dans cet article, vous apprendrez à utiliser les variables de référence de modèle, souvent appelées «références de modèle», dans Angular.

Dans Angular, les composants ont une templatepropriété qui contient des éléments et d'autres composants. Une variable de référence de modèle est une fonctionnalité qui nous permet d'accéder à une partie de notre modèle.

Il peut s'agir d'un élément, d'un composant ou d'une directive. Les variables de référence de modèle sont intelligemment implémentées et peuvent être utilisées de différentes manières.

La première pourrait être d'exporter simplement une référence à un élément. Ici, nous pouvons attacher un #à un <input>et fournir un nom de variable (d'où la référence de modèle 'variable'):

<input type="text" #coffee>

Vous pouvez considérer cette syntaxe comme une "exportation". Nous exportons une référence à l'élément.

Cela signifie que nous pouvons maintenant accéder aux propriétés de cette variable de référence comme si elle nous avait été renvoyée via du JavaScript simple (pensez à ce que vous obtiendriez en utilisant document.querySelector('input')et c'est ce que nous avons ici) :

<input type="text" #coffee>

<p>{{ coffee.value }}</p>

Cela déconnecterait une chaîne vide coffee.valuecar nous n'en avons pas value. Notre coffeevariable nous donne directement un HTMLInputElement.

Pour que nous puissions voir la valeur au fur et à mesure que nous tapons, nous aurions besoin d'introduire la ngModeldirective :

<input type="text" ngModel #coffee>

<p>{{ coffee.value }}</p>

Essayez-le et tapez quelque chose dans le <input>:

Voici donc la prochaine grande fonctionnalité des références de modèles.

Exportons une référence vers notre ngModelet changeons le contexte de ce qui #coffeenous renvoie.

En spécifiant #coffee, nous laissons implicitement Angular décider quoi exporter, car nous ne spécifions rien d'autre que la liaison à l'élément.

Nous relions ngModel, qui fait désormais « partie de » notre <input>. Exportons-le :

<input type="text" ngModel #coffee="ngModel">

<p>Value: {{ coffee.value }}</p>
<p>Pristine: {{ coffee.pristine }}</p>
<p>Touched: {{ coffee.touched }}</p>

En passant #coffee="ngModel", nous lions explicitement une référence à notre ngModeldirective suivie.

Nous n'avons plus de HTMLInputElement. Nous avons une référence à NgControl.

Vous pouvez vérifier le code source de NgControl ici, qui étend les classes NgControl et AbstractControlDirective .

Pourquoi regardons-nous cela? Parce qu'il vous montre toutes les propriétés disponibles pour vous, c'est exactement pourquoi nous avons référencé non seulement valuemais pristineaussi touched.

Essayez-les ci-dessous, notre variable de référence de modèle reflète lengModel :

Nous pouvons approfondir cela et accéder à une référence de modèle à l'intérieur d'un composant , afin que nous puissions accéder aux propriétés et aux méthodes à l'intérieur du classet pas seulement du template.

Ceci est réalisé grâce à l'aide peut -être TemplateRefou ElementRefaux côtés d'un @ViewChilddécorateur. Lisez l'article ci-dessus sur la façon de le faire et un travail plus approfondi, mais cela ressemble essentiellement à ceci :

export class AppComponent {
  @ViewChild('username') input: ElementRef<HTMLInputElement>;

C'est une bonne introduction aux références de modèles, et j'espère que cela vous permettra de mieux comprendre comment les utiliser, quand et où. Non seulement cela, mais à quoi s'attendre lorsque vous déclarez une référence de modèle et comment exporter également des références à des éléments tels que des directives.

Bon reffing !
