What's the advantage of PyQt5 containers?

Why do you even need containers?
The fact that they're automatically stretching the view is that I've already understood, but is there any other useful properties of the containers?

Containers are general-purpose classes that store the values of the intended type. There are two types of containers:
Consistent - the elements are stored behind each other (contin). Examples of successive containers are QList, QVector, QLinkedList.
The associated elements are stored as a pair of keys. Examples of associated containers are QMap and QHash.
Did I answer your question? :

The encoding you are using, the ISO 8859-15, best known as Latin-9, only has 256 characters; and those you try to print are not among them. I think the solution is the one that the partner points out in the comment: use the UTF-8.It could be like this:#!/usr/bin/python # -*- coding: utf-8 -*- import os, sys sara1 = '░█▀▀▀█ ─█▀▀█ ░█▀▀█ ─█▀▀█' sara2 = ' ▀▀▀▄▄ ░█▄▄█ ░█▄▄▀ ░█▄▄█' sara3 = '░█▄▄▄█ ░█─░█ ░█─░█ ░█─░█' print (sara1) print (sara2) print (sara3) You can see the Latin 9 standard characters http://www.columbia.edu/kermit/latin9.html

I got the same problem. The pycurl redesigns didn't yield results. It's like a virtual network interface in Windows:C:\Windows\system32>netsh interface show interface Turn off all the interfaces except the main one that you're on the Internet and the problem should go. Looks like curl's choosing an interface for DNS requests in its logic... maybe just picking up the first in the Windows interface and trying to work through it. I didn't know that much. ♪ ♪

This gets complicated at times, I still can't reproduce your problem... :(. Trying to simulate it with what you explain, I've reached the following code:from bs4 import BeautifulSoup import requests html = requests.get("http://esingenieria.uca.es/centro/datos-del-centro/equipo-directivo/") Tit_Datos_Tot = BeautifulSoup(html.text,"html.parser").select('tr[class^="row"]') Tit_format = str(Tit_Datos_Tot[1:3][0]) Sopa = BeautifulSoup(Tit_format, "html.parser") Sopa_td1 = Sopa.select('td[class="column-1"]') Sopa_td2 = Sopa.select('td[class="column-2"]') Sopa_td1_Limpio=None Sopa_td2_Limpio=None for i in range(len(Sopa_td1)): #Sopa_td1 y Sopa_td2 tienen el mismo número de elementos. Sopa_td1_Limpio = Sopa_td1[i].get_text() Sopa_td2_Limpio = Sopa_td2[i].get_text() print(Sopa_td2_Limpio) The indices I used to select the portion of your example are ind_tot_ini = 1 e ind_tot_fin = 3. I have omitted all the character replacement procedures (in my case the result is the same with or without those lines). Well the exit is as follows: The chain containing Sopa_td2_Limpio is as follows:'High School of Engineering \n\nAvenida de la Universidad de Cádiz, no 10\n\n11519 - Puerto Real, Cadiz'We do something different, it's clear. Use http://docs.python-requests.org/en/master/ to get the text from the url but this is indifferent. See if from this we can move forward and deal with the problem. See what differences you find (if I'm not too lost myself and away from what you're trying to do).EDITION:As suggested in a comment html is not obstinated from the web directly but from a local file (index.html). The file can be opened with open without problems unless the method is used readlines() to get the data. The problem is, readlines returns List with each line of the document. This is what initially caused the whole problem.You must not use readlines It is readreturning an object str or bytes depending on the read mode and containing the raw text as you get it from the url. Despite the class builder BeautifulSoup accepts an object _io.BufferedReader (which returns open on Python 3.x) directly as input argument as you can see on the https://www.crummy.com/software/BeautifulSoup/bs4/doc/#making-the-soup :from bs4 import BeautifulSoup Tit_Datos_Tot = BeautifulSoup(open("index.html", 'rb'),"html.parser").select('tr[class^="row"]') Tit_format = str(Tit_Datos_Tot[1:3][0]) Sopa = BeautifulSoup(Tit_format, "html.parser") Sopa_td1 = Sopa.select('td[class="column-1"]') Sopa_td2 = Sopa.select('td[class="column-2"]') Sopa_td1_Limpio=None Sopa_td2_Limpio=None for i in range(len(Sopa_td1)): #Sopa_td1 y Sopa_td2 tienen el mismo número de elementos. Sopa_td1_Limpio = Sopa_td1[i].get_text() Sopa_td2_Limpio = Sopa_td2[i].get_text() print(Sopa_td2_Limpio) I downloaded the web and applied the code on index.html located \esingenieria.uca.es\centro\datos-del-centro\equipo-directivo\index.html within the directory created by HTTrack and the correct output, I identify the previous one I put in the answer.

Hi. I'm not an expert but I guess if you want to do it alone with CSS and no style bookshop I recommend that you study what the positions of the objects are (Absolute, floating, absolute) besides that you will have to apply JS Anyway here I leave you a link with an example made in bootstrap 4.0.0, it's almost like what you want. https://bootsnipp.com/snippets/dl6ez Another example: DEMO: https://azmind.com/demo/bootstrap-carousel-multiple-items/ Instructions: https://azmind.com/bootstrap-carousel-multiple-items/

This regular expression separates the words containing a "+":([A-Z]+)[+]?([A-Z]*) It reads like this:([A-Z]+) Order one or more letters and capture the found calce.[+]? Recognize zero or a "+" character (i.e., an optional "+").([A-Z]*) Recognize and capture zero or more letters below.The beauty is that using re.findall, the match object the result will always return a tupla with two entrances: the name and the last name (or a empty string, if you have no last name).This pattern does not serve to validate, as it recognizes words like "ABC+" that are not the last name.Demoimport re palabras = ["TED", "TED+PLUS", "WCDWC"] patron = re.compile("([A-Z]+)[+]?([A-Z]*)") for palabra in palabras: m = patron.findall(palabra) nombre, apellido = m[0] print(nombre, apellido) produces:TED TED PLUS WCDWC Process finished with exit code 0

The problem was described in the issues. https://github.com/material-components/material-components-android/issues/1241 And that's the solution. https://github.com/material-components/material-components-android/pull/1242 Now, using app:chipIconUseDrawableSize="true"the size of the drawable rather than chipIconSize will be used.Works. chipIcon and checkedIcon♪Estimate closeIcon - I don't know.

First start by giving the correct names to the variables. It may seem like a beast detail, but https://hackernoon.com/the-art-of-naming-variables-52f44de00aad .At no time was mentioned the minimum value, only the maximum amount to be paid and the debt value, so we only have:divida = int(input()) maximo = int(input()) Exactly in this order, which is what the statement says.Then in the loop you should check if the debt is not zeroed (i.e. if divida > 0).And inside while you discount the value of the debt, attentive to the case in which it is lower or equal to the amount to be paid (for in this case it must be held)while divida > 0: # enquanto ainda deve algo print("(antes) {}".format(divida)) if divida <= maximo: # zerar a dívida divida = 0 else: # descontar o valor máximo do valor da dívida divida -= maximo print("(depois) {}".format(divida)) Notice that "before" and "after" prints are made... before and after discounting the value https://ideone.com/FEltLJ the code running.

What are Schemas?These are collections of objects within a given database, which organize various aspects and are important for security segmentation, facilitating the administration of objects and data.From SQL Server 2005, any database object ceased to belong to a user to belong to a Schema. Thus, Schema is the bridge of association between the user (or group of users) and one (or more) bank object(s).What are the advantages of using it?The first advantage is the permission of users and groups. When a user is authorized in a Schema, it can be authorized in multiple databases at the same time whose objects are included within a Schema.The second advantage is the physical grouping of the data. Some servers, such as the latest versions of SQL Server, allow objects from the same Schema, even if they are divided into multiple databases, to be physically grouped for backup and load administration.In what situations is your use recommended?In databases with multiple databases (which have multiple systems, for example) and it is necessary to authorize or revoke users and groups quickly.In databases whose permission is an essential feature for data security (ancient client-server systems, for example, which rely heavily on the database for implementing business rules).In data segmentation by user group. You can have in the same database two tables with the same name, each being in a different Schema.
