Calculadora Simple:

En este post veremos el proceso para la elaboración de una calculadora simple y su uso.

Creando la calculadora

Como podemos ver esta calculadora es bastante simple. Usamos “Print” para que muestre el contenido en pantalla (dicho contenido debe estar dentro de paréntesis y con comillas), y para crear una variable, escribimos primero su nombre “num1” seguido de un “=”, en dónde el contenido que siga del igual será la variable. Cómo en este caso hablamos de un Entero colocamos “int”, seguido de un “input” para que el valor del entero lo de el usuario.

Tras pedir otro número para poder realizar la operación, ahora desplegaremos los resultados. En este caso escribimos primero la frase, y dentro del paréntesis pero déspues de las comillas y una coma, escribimos la operación según sea la que necesitemos (num1 + num2, num1 – num2, etc.)

Ahora lo ejecutamos en Python.

Ya quedó, una calculadora realmente simple. Ahora se mejorará un poco para tratar de hacerla más funcional.

Ahora desplegamos un pequeño menú con un while para que el usuario pueda realizar sus opeaciones cuantas veces quiera.Contiene también un botón de salida y le añadimos la función de potencia. Tambien le añadimos una opción para que el programa vuelva a empezar si el usuario no teclea una de las opciones que se le muestra.

Cómo se ve en Python:

Realizar calculadoras es bastante positivo para aquel que apenas va empezando a programar en un determinado lenguaje, ya que le ayuda a comprender la sintaxis y uso de varias herramientas simples tales como el int, while, if etc.

We are going to create a programm that first ask the user for two integer values and then, with these two numbers, calculate the sum, the difference, the product, the division (no decimal point) and the remainder of the division.

Here is the code and how it runs:

Now, let’s explain how it works.

First, we need the two variables as numbers. We have to ask the user for them, so we write a String to display a message. We write the name that we want to give them to identify (for example here, num1 and num2). After that, the symbol = to assign a value and the int() function, because if we forget it, the programm will take it as a String and we couldn’t make math operations with that inputs.

Then, we declarate all the math operations we will perform. The symbols we use are + for sum, – for subtration, * for multiplication, / for division and % for the remainder of the division (the first number between the second). Notice that we have doble // in division, it is because we don’t want decimal points. You could skip this step and just write the operation in the result you are going to print, but I prefer this way.

Finally, we write print() and a String inside quotes, after that a coma and the name of the variable we already done.

And that’s it, now you can run and try your programm. Hope it helps

Here I am going to show a program that asks the user for two numbers (integers) and then displays the sum, difference, multiplication, division (with no decimals) and remainder of these numbers. In this program you will be able to identify the inputs and outputs, which I already talked about and explained in a previous blog.

The code for this is as follows:

And it runs like this:

So here, the inputs are 12 and 10, and the outputs are 22, 2, 120, 1 and 2.

Hi there,

So we were given the following instructions for this first little problem :

Ask the user for two integer values, then use those two values to calculate and show the following:

• The sum of the two numbers.
• The difference of the two numbers.
• The product of the two numbers.
• The integer based division of the two numbers (so no decimal point). First divided by second.
• The remainder of integer division of the two numbers

Which I answered with the following (quite long) bit of code, which is a bit more than necessary I assume. 

So the initial idea behind the assignment was to cover basic user input (asking for 2 numbers) along with basic output (printing the results of the operations).

The user input is dealt with with the built-in function in Python 3, input(), which will wait for the user to give a value to continue. You can actually add some text to it to let the user know what you’re expecting from him. Here I asked on line 2 and 3 to enter a “First value” and a “Second value”.

I performed operations on those values, such as adding, substracting, multiplying and dividing them, as required in the instructions, and used the print() function to display them to the screen.

To perform all of this, I created a get_results() function, which allows me to use all this code anytime I want later on, without having to re-type the whole thing.

The thing that bothered me though, was that if you entered something else than an integer when asked for a value, you would just crash the program because it wouldn’t be able to perform all the operations. Yeah, you can’t really substract a “cat” and a “zebra”. So what I did about it is I created another function

First of all I have never used a blog so I may learn a thing or two while blogging. Also I would like to mention that I have never used terminal for writing codes and I have no idea of how the language but I’m willing to learn because I have always been a fan of Jailbreak and video games so it really doesn’t matter if I have oversleep while studying.

Atom is the program that we will use and I watched this video to learn the basics. 

It is a series tutorial on how to use atom and change the preferences to make it more simplified and easier to use.

After watching the videos and making my research I finally could run the code that was written on Atom and run it on Terminal.

My hobbies is play video games and watch F1. I’m willing to learn about coding and I want to learn more about the language and be part of the world of coding specially JailBreak. I’m still waiting for the Jailbreak for iOS 10.2
