Variáveis na Programação

Se você está começando sua jornada como programador, é importante entender o conceito de variáveis.

Programação

O que são Variáveis?

Em programação, uma variável é um espaço na memória do computador que armazena um valor.

Como criar Variáveis?

Por exemplo, em Python, para criar uma variável chamada "idade" e atribuir o valor 25, escreveríamos: Idade = 25

Tipos de Variáveis

Existem vários tipos diferentes de variáveis

Numéricas; Data e Hora; Lógicas; Texto.

Utilizando Variáveis

Você pode utilizar uma variável numérica para armazenar o resultado de uma conta matemática, ou uma variável de texto para armazenar uma mensagem.

As Variáveis são muito úteis

Possível utilizar uma variável para modificar seu valor ao longo do código. Por exemplo, você pode incrementar ou decrementar o valor de uma variável numérica
