To understand the conditional, first we have to know what is a control flow. normally it follows a linear path.

Conditionals introduce a branch in the control flow, when you make an “If” it will ask if its true or false, depending on the result it will follow a path.

else is another statement inside the “If”, it will optimize your program in order to do not write again the “If” conditional.

“Else” allows you to follow a path when the main statement is false, so your program will continue.

it is maybe the most famous conditional in programming, it works when you want to divide a statement between true or false, in other words Boolean logic. “If” conditional is composed by the main statement, the true and the false answer.  There are many others options that can be added to the “If” conditional as “else”, “elif”, etc.

these conditionals are just to improve your main statement.

In this code we used the If statement with the positive answer to the statement, elif works as another conditional inside the If. Else works as the negative answer to the main statement.

En Python  contamos con un gran numero de herramientas en base a la programación, una de ellas es la calculadora, el realizar cualquier tipo de operaciones en base a lo que nosotros pidamos.

en el tutorial, podemos ver un ejemplo del uso de la calculadora como calculadora

En este caso realizaré una multiplicación sencilla utilizando variables (no es necesario el uso de variables). en el cuarto reglon podemos ver que a la variable “t” se le agregó un renglón en la suma, ese reglon es una variable independiente que python 3 reconoce, esa variable toma como valor el último número impreso. después si le aplicamos el atributo “round” podemos redondear el número a las cifras solicitadas, en este caso se redondeó a 2 cifras antes de los enteros.

Python tiene muchas variantes para poder modificar la información que ingresas en el sistema, este es un ejemplo de como puede ser modificada; con string.capitalize() puedes hacer que de las palabras que ingreses, la primera letra la conviertas en mayúscula. esto es utilizado para la ortografía.

String.format() es un recurso para introducir strings a tu programa de una manera más sencilla, esto es útil cuando manejas grandes cantidades de información que se tienen que repetir.

String.strip() es utilizado para eliminar espacios en tu información ingresada

Using strings is a variable of words, is necessary for programming in too many cases, for example; when you compile information or you have to use one large word and you want your programm to make it shorter.

Python has a code that shows a list a special rules, metaphors of how to program and (in my humble opinion) how to have a better life…

phrases as: “errors should never pass silently”, “now is better than never”, “special cases aren´t special enough to break the rules”… all of those can be relationated with daily life´s situations. Your interpretation is the only that matters. follow those metaphors not only for programming. be a better person before a better programmer…
