As an example of what I am looking to achieve, I have created a Person class that inherits from Speech:

class Habla:
    def expresion(frase, grita):
        if grita:
            return frase.upper()
        else:
            return frase

class Persona(Habla):
    def __init__(self, frase, grita):
        self.grita = grita
        self.frase = super().expresion(frase, grita)

persona = Persona(frase="Aghh!", grita=True)

The problem I have is that I get an error when executing the method expresionof the class Speak.

I get the error:TypeError: expresion() takes 2 positional arguments but 3 were given

I suspect that the parameter selfis involved in the matter, but I don't know the cause.

I tried with the debug but I couldn't find when 3 parameters are passed to the method expresion.

Thanks in advance for any explanation you can give me. I emphasize that my goal is to be able to execute an inherited method inside a class and that I would like to know why I receive this error.

All the best.

I have a table with many fields. According to this page , the error is due to the fact that in one of the fields I am trying to insert data that exceeds the maximum length established in the table for this field. To solve it, it is recommended to identify the field (or fields) and correct the size allowed in the table. But because the table in question is very large I have spent more than 12 hours trying to find the guilty field.

The method I am using is the following:

I did one SELECTin which I specified field by field an CASTequal to the one in the table and I launched the query for each field until I received the same error that I get when using the INSERTin all the fields.

Is there an effective way to identify the responsible field?

I've run a script that deletes all files in a folder after 5 minutes from the time they were last created or modified.

Taking into account the eventuality that some file is created at the moment of the change of the time zone, I implemented some conditions that make sure that the file is also deleted in the arc of those 5 minutes. The method I used is effective, but I learned from a more experienced programmer that there is a more efficient way, probably using some library or some method datetimethat I don't know.

I am a lover of clean code and I would like to know this other method to continue improving professionally. First of all, Thanks.

Here is the part of the code that concerns the matter:

# fTime es la fecha de ultima modificacion del archivo
# fPath es el directorio y nombre completo del archivo

now = datetime.now()  # Obtiene hora actual

if now > fTime:
    diff = now - fTime  # Actua normalmente o cuando el tiempo va arriba de 1 o 2 horas en la zona horaria
else:
    diff = fTime - now  # Actua cuando el tiempo va atras de 1 o 2 horas en la zona horaria

minutes = diff.seconds / 60  # Transforma horas en minutos

if 55 < minutes < 65:  # Arregla el tiempo si cambia de 1 o mas horas adelante o atras
    fixTime = 60 - minutes
    if -5 > fixTime > 5:  # Elimina archivo con diferencia de 5 minutos adelante o atras respecto a la hora actual
        remove(fPath)
else:  # Si no hay cambios en la zona horaria el control pasa por aqui
    if minutes > 5:  # Elimina los archivos con 5 minutos de diferencia adelante respecto a la hora actual
        remove(fPath)

Following W3schools explanation , lambda functions are anonymous functions that can be used inside other functions. I think I do not fully understand its usefulness and use despite the many examples on the page.

Here are my doubts:

In the following example, where is the value of the variable a declared?

def myfunc(n):
  return lambda a : a * n

mytripler = myfunc(3)

print(mytripler(11))

If mytripler()it is the lambda it no longer seems so anonymous to me.

Why use lambda if you can do the following?

def myfunc(a, n):
  return a * n 

print(myfunc(3, 11))

When you say that they are anonymous functions, do you mean that they are functions that don't have a name by which to call their execution like this MiFuncion()?

Statement of the problem

I have written a JavaScript library that I want to make accessible in third-party projects (just like jQuery), for this I have thought of using the JSDelivr service and its GitHub option.

I first made a Package npm through GitHub (thinking it was necessary) but then I noticed that it didn't work and only after doing a Release on GitHub was it possible to import the library using:https://cdn.jsdelivr.net/gh/user/repo@version/file

I also had to make a new version of the program through Release but when doing the same thing in Packages I couldn't find a way, so I have a Release version v1.0.1and a Packages version v1.0.0and I don't know how to align the Packages version.

conclusion

• What is the difference between Packages and Releases, both are required for the JSDelivr service?
• How do you create a new version of a GitHub Package (eg: v.1.0.1)?

Problem

I have an svg file that has a link <a>inside it, the function of this link is to repeat the animation of the svg every time it is clicked . It works correctly if I open the svg file in a browser, but when I import the html file using a tag <img> the animation works but the link does not seem to be recognized since when it is positioned over the svg the cursor does not change its default to the pointer and when doing click does not repeat the animation .

Browsers in which this situation is verified: Firefox, Chrome, Edge.

I am trying to access the content of a tag <object>that uploads a file. Specifically, I want to access the id of some of its elements and I've tried doing it with CSS and JavaScript, but nothing seems to work. I cannot access the id or classes of the elements that are loaded from the file.

The problem persists despite the type of file used, I have tried with html and svg files.

Label <object>:

<object id="obj" data="test.svg" type="image/svg+xml"></object>

SVG file:

<svg width="680" height="370" style="border-radius:30px" version="1.1" viewBox="0 0 179.91 97.897" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
    <path id="test" d="m9.2398 47.875 22.601 6.4716 69.367 0.0251c0.68665 2.51e-4 1.4406-0.39775 1.4217-1.5326l-3.7e-4 -25.974-74.08-17.624z" fill="#333" opacity=".5" style="mix-blend-mode:color-dodge"/>
</svg>

JavaScript with which I try to access the id:

<!-- jQuery full con ajax -->
<script src="https://code.jquery.com/jquery-3.5.1.js" integrity="sha256-QWo7LDvxbWT2tbbQ97B53yJnYU3WhH/C8ycbRAkjPDc=" crossorigin="anonymous"></script>

<script>
    $(window).on('load', function(){ 
        console.log( document.getElementById('test') )
        // Devuelve: null
    });

    $(document).ready(function(){
        console.log( document.getElementById('test') )
        // Devuelve: null
        
        console.log( $('#obj').contentDocument )
        // Devuelve: undefined
    });
</script>

CSS doesn't detect the id either:

#obj {color: red !important} /* No funciona */
#test {fill: red} /* No funciona */

The tag <embed src="..." \>behaves the same way

I have a CSS animation that uses keyframeswhich is executed only once when the page loads (see example cited) .
The result I am looking for is a JavaScript or JQuery control that prevents the execution of the animation until it is in the area of ​​the page that the user is viewing (the viewport ) .

I have connected the animation to a class that I apply to the element with JavaScript but I have no idea how to capture the event that should trigger the action.

How is the presence of an element in the viewport detected?

@keyframes example {
  from {background-color: red;}
  to {background-color: yellow;}
}

.animate {
  animation-name: example;
  animation-duration: 4s;
}

#cube {
  width: 100px;
  height: 100px;
  background-color: red;
}

<!-- La clase animate viene añadida posteriormente con JavaScript -->
<div id="cube" class="animate"></div>

I am animating an SVG logo with CSS and I have already managed to create several effects but I cannot understand how to make one of the SVG paths move horizontally (see image).

All my attempts to import the SVG as a file and then style it have also failed, forcing me to put the entire SVG inside the HTML, which I'd rather avoid.

I have tried various things like modifying the widthwithout getting any results. Here I leave my code with the two effects done so far so you can see the method used:

@keyframes light-lines{
    0%{fill:#a9a9a9;opacity:.9}
    100%{fill:#333;opacity:.5}
}
.light{
    animation: light-lines 2s ease-out infinite alternate;
}
@keyframes invisible-text{
    0%{opacity:0}
    100%{opacity:1}
}
#svg-text{
    animation: invisible-text 3s ease-in-out 2s infinite alternate;
}
.mountain{
    /* ? */
}

I want to prevent Google Analytics from recording the activity that I have on my own website to avoid contaminating the data it collects, for this I would like to put a filter that excludes the IP address of my router so that all my devices are excluded even though I know it is not the best option because it would not register the data of others who share my same IP on the internet, but the system that uses cookies is not feasible in my case. Other options that do not include cookies are welcome.

I have noticed that there is a filter that Google Analytics gives us by default with this objective but I don't know how to configure it, it is the one shown in the following image:

It seems unintuitive to me, after testing and reading the documentation I have not been able to find a way to make it work. It keeps recording the activity of my devices.

I have noticed that in the Google Docs spreadsheets there is an add-on that allows you to interact with the Google Analytics account to access your statistics and I have followed the steps of the official Google guide .

Once the plugin is installed and granted access to my Analytics account after requesting the creation of a new report, it gives me the following error:

"""
There's a problem

It looks like you don't have any Google Analytics
accounts with data.

Note: this add-on integrates with your existing Google
Analytics data. It is not a generic data analysis tool
for Google Sheets.

To learn more about Google Analytics, visit:
https://google.com/analytics.
"""

And then this other one:

"Error: User has no Google Analytics account data."

I thought it was an access problem but then I saw that this add-on does not require the configuration of the Google Analytics API , nor the creation of authentication keys or other similar systems.

Other relevant information is that my Google Analytics account was created only two days ago and has not collected much data, but I have already verified the existence of them.

Could it be that I need to wait longer for the amount of data to be enough to meet the "expectations" of the add-on or do you think this is a different problem?

PS: For those who are curious about why I want to connect these two services, you can find more information in the guide link. In short, its usefulness is to be able to view Google Analytics data graphically on any website (including the monitored site).

Although in Python all elements within a class are public by default, there is a way to emulate a certain degree of privacy for them by using two underscores at the beginning of the method or attribute name, eg: __contraseña. This really just renames the attribute to avoid collisions with internal Python methods, such as the method __init__, and renames the attribute by appending it _NombreClaseto the beginning, so that the attribute I used as an example would be _NombreClase__contraseña. And if we called the object by its attribute, it would give us an error, although it would still be completely accessible if we make the call using the name that is automatically assigned to it, as seen in the following example:

class MiClase:
    def __init__(self):
        self.__privada = "Mensaje secreto"
    
    def devuelve_privada(self):
        return print(self.__privada)

objeto = MiClase()

objeto.devuelve_privada()
#>> Mensaje secreto

print(objeto._MiClase__privada)
#>> Mensaje secreto

objeto.__privada
#>> AttributeError: 'MiClase' object has no attribute '__privada'

Due to this, I thought that the private attributes of a class in Python were only intended to remind or make notice to the developers involved in a project that said attribute should not be changed lightly or that a specific method of the class should be used. to carry out said modification that performs controls or validations of some kind on the new value to be inserted. But then I came across this code which I have simplified a bit for the example:

class Usuario:
    def __init__(self, usuario, contraseña):
        self.__nombreUsuario = usuario
        self.__contraseña = contraseña

    def set_contraseña(self, contraseña):
        self.__contraseña = contraseña

    def get_contraseña(self):
        return self.__contraseña

In this case of the creation of a new user, this practice is carried out in a context where no type of validation is carried out (already done previously) and everything indicates that it is used for security reasons, and I was wondering what type security can offer this. Due to the previously exposed vulnerability, knowing the name of the class and the attribute, its value can be changed. I also don't really understand why security measures should be created for this inside a code that runs on a server.

I feel like I'm not taking something into account, because those who did this are very experienced programmers and I'm sure they must have a valid reason for it.

In Python I can append values ​​to a list using the append() function among other things, but with tuples this all changes and the way they are handled is different. Its structure seems very similar to that of a list, and I would like to know its usefulness or purpose.

Tuples in Python have this structure:

a = (1,2,3,4)

While the lists is another:

b = [1,2,3,4]

I would be grateful if someone could explain to me why tuples are necessary in Python and in what cases they should be used.

As the title says when launching the command attribin the CMD to change the properties of a file the command is not recognized although in the past I used it without problems.

I was recently making changes to the system (not user) Path variable and some were removed, I think there might be a connection.

If I type attribin C:\Windows\System32\I get a list of all the dlls in the folder like so:

A                    C:\Windows\System32\xwtpdui.dll
A                    C:\Windows\System32\xwtpw32.dll
A                    C:\Windows\System32\X_80.contrast-black.png

But if I do it from C:\UsersI get:

"attrib" no es reconocido como un comando interno o externo,
 un programa ejecutable o un file batch.
