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：

1. 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。

2. 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 :
# Constructor
def __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 False
if num % i == 0 :
return False
# if number is prime then return True
return True
# Main code 
if __name__ == "__main__" :
# input number
num = 11
# make an object of Check class
check_prime = Check(num)
# method calling
print(check_prime.isPrime())
num = 14
check_prime = Check(num)
print(check_prime.isPrime())        

Output

輸出量

True
False
