python判斷素數程序

This program will check whether a given number is Prime or Not, in this program we will divide the number from 2 to square root of that number, if the number is divided by any number in b/w then the number will not be a prime number.

該程序將檢查給定數字是否為質數 ，在此程序中，我們將數字從2除以該數的平方根，如果該數字除以b / w中的任何數字，則該數字將不是質數數。

We are implementing this program using the concept of classes and objects.

我們正在使用類和對象的概念來實現該程序。

Firstly we create the Class with Check name with 1 attributes ('number') and 2 methods, the methods are:

首先，我們使用Check名稱創建具有1個屬性( 'number' )和2個方法的Class，這些方法是：

Constructor Method: This is created using __init__ inbuilt keyword. The constructor method is used to initialize the attributes of the class at the time of object creation.

構造方法 ：這是使用__init__內置關鍵字創建的。 構造函數方法用于在創建對象時初始化類的屬性。

Object Method: isPrime() is the object method, for creating object method we have to pass at least one parameter i.e. self keyword at the time of function creation.

對象方法 ： isPrime()是對象方法，要創建對象方法，我們必須在函數創建時傳遞至少一個參數，即self關鍵字。

Secondly, we have to create an object of this class using a class name with parenthesis then we have to call its method for our output.

其次，我們必須使用帶有括號的類名來創建此類的對象，然后必須為其輸出調用其方法。

Below is the implementation of the program,

下面是該程序的實現，

Python代碼檢查給定數字是否為質數 (Python code to check whether a given number is prime or not)

# Define a class for Checking prime number class Check :# Constructordef __init__(self,number) :self.num = number# define a method for checking number is prime or not def isPrime(self) :for i in range(2, int(num ** (1/2)) + 1) :# if any number is divisible by i # then number is not prime# so return Falseif num % i == 0 :return False# if number is prime then return Truereturn True# Main code if __name__ == "__main__" :# input numbernum = 11# make an object of Check classcheck_prime = Check(num)# method callingprint(check_prime.isPrime())num = 14check_prime = Check(num)print(check_prime.isPrime())
