Mario16's questions

I have been searching for various alternatives but I am not able to sort the array from least to greatest without sort(). How can I detect?

serie = [4,3,2,1,6,8,7]

for i in serie:
    if i > 0:
        i = i - 1
        print(i)

I'm learning how to use buttons in Swift and I'm changing the color of several of them separately when they are pressed. The problem is that when I press the second button the first one also changes color, and I find it somewhat strange since in theory they are two different functions and one should not affect the other. Anyone know what might be happening?

    //Outlets

    @IBOutlet weak var myButton: UIButton!
    @IBOutlet weak var button2: UIButton!


    override func viewDidLoad() {
        super.viewDidLoad()
    
        //Buttons
        myButton.backgroundColor = .green
        button2.backgroundColor = .blue
    }

    @IBAction func buttonAction(_ sender: Any) {
    
        if myButton.backgroundColor == .green
        {
            myButton.backgroundColor = .blue
        } else
        {
            myButton.backgroundColor = .green
        }
    
    }

    @IBAction func buttonAction2(_ sender: Any) {
    
        if button2.backgroundColor == .blue
        {
            button2.backgroundColor = .gray
        } else
        {
            button2.backgroundColor = .blue
        }
    
    } 
}

I am using some very simple conditionals and it gives me the following error:

unary operator cannot be separated from its operand.

import Foundation
import UIKit

//SENTENCIAS IF

let myNumber = 5

//Una barra invertida y los paréntesis lo que aparece es la variable
//siempre y cuando tengamos un texto

if myNumber >= 5 && <= 10
{
    print("\(myNumber) es mayor que 5 y es menor que 10")
} else

{
    print("\(myNumber) es mayor que 10")
}

Does anyone know what the error could be?

I am trying to save the vowels in the variable "vowel" separating them by commas, but python takes it as a complete text.

letra = input(str("Introduzca una letra: "))
vocal = "a","e","i","o","u"

def abc(letra,vocal):
    if letra == vocal:
        print("True")
    else:
        print("False")    

abc(letra,vocal)

How can I get the variable to take the letters separately?

#Definir una función que calcule la longitud de una lista
# o una cadena 

def longi(numero,lista):
    lista = [1,2,3,4,5,36,7,8,9,3,4,5,6,7,5,4,3,4]
    numero = 0
    for i in lista:
    numero = numero + 1

    print(numero)

longi(numero,lista)        

I am trying to define a function which counts how many numbers have a list, but when calling the function with the arguments it tells me that they are not defined. Does anyone know why?

This is the code:

procedure TForm1.ButtonDotClick(Sender: TObject);
begin
  if (POS('.', txtResult.Text))<>0 then
  exit
  else
  txtResult.Text := txtResult.Text + ButtonDot.Caption;

end;

The error that appears is the following: E2003 Undeclared identifier: 'Caption'

Can anybody help me?

procedure TForm1.ButtonPlusLessClick(Sender: TObject);
var
pMinus: Real;

begin
  pMinus := StrToFloat(txtResult.Text);
  txtResult := FloatToStr(-1 * pMinus);
end;

The error that appears is the following: E2010 Incompatible types: 'TEdit' and 'string'.

I am making a code in bash and it does not execute correctly. I think it may be a bug found in the bashrc file .

    #!/bin/bash

   
    #Variables Globales


    function Unconfirmedtransactions()
    {
       echo '' > ut.tmp 

       while [ "$(cat ut.tmp | wc -l)" == "1" ]; do 
           curl -s "$unconfirmed_transactions" | html2text > ut.tmp
       done 

       hashes=$(cat ut.tmp | grep "Hash" -A 1 | grep -v -E "Hash|\- -|Time")

       echo $hashes

       tput cnorm
    }

    parameter_counter=0; while getopts "e:h:" arg; do
        case $arg in 
            e) exploration_mode=$OPTARG;let parameter_counter+=1;;
            h) helpPanel;;
        esac 
    done

    tput civis 

Apparently the variable $TERMhas no value assigned.

I am trying to create the Figure class with its respective functions but it tells me that Figure is not defined. What is the mistake?

class Figura:

    def __init__(self):

        self._lados = None

    def main():

        triangulo = Figura()
        cuadrado = Figura()
        cuadrado._lados = 4
        triangulo._lados = 3
       
        print(f"El triángulo tiene {triangulo._lados} lados.")
        print(f"El cuadrado tiene {cuadrado._lados} lados.")
       
     if __name__ == '__main__':

        main()

ERROR => NameError: name 'Figure' is not defined
