20 de jul. de 2023 · Aprenda a usar o switch case em Python, uma estrutura de controle que permite processar várias condições ou casos em um único bloco de código. Veja exemplos, comparações, dicas e erros comuns neste artigo.
Neste artigo, exploraremos como implementar a funcionalidade de “switch case” em Python utilizando diferentes abordagens, incluindo o uso de cadeias if-elif-else, dicionários e a inovadora estrutura match-case introduzida no Python 3.10.

As said above, the switch is a construct that can be used to implement a control flow in a program. It can be used as an alternative to the if-else statements or the elif ladder when we have a single variable/ an expression that we use to make the decision. Using this instead of the multiple if-else statements makes the code look cleaner, quicker, ...
Switch statements mainly consist of the condition and different cases which are checked to make the condition. It takes a value or a variable or an expression as an input. Each case corresponds to a particular value. It checks if any of the cases is equal to the input and based on that respective statement(s) is(are) executed. It also allows us to ...
Before using the other constructs, first, let us use the elif ladder to implement the switch control. The following code shows an example ofgiving the output as the number in words. Example on implementing switch case using elif ladder: Output: Here, when we call the function, the elif ladder is executed. And the number given as input is checked wi...
We can use a dictionary to implement the switch case. We know that the dictionary holds the key-value pairs. It can have the keys as the condition/ element to be checked and the values as the elements to be printed or the functions to be executed.
Besides using the dictionary, we can also use Python classes to implement the switch construct. The classes in simple words are the collections of variables and functions that act as a single unit. We can define a class using a ‘class’ keyword’. The below code shows an example of implementing the switch to get the moth given the number, using the c...
Q1. Write a switch case program to check if a letter is a vowel Ans. We can write the vowels as the keys of the dictionary and value as the string ‘It is a vowel’. And the default case printing it is not a vowel Example of checking if a letter is vowel or not: Output: Q2. Write a program to check if the function is positive or negative or zero. Ans...
