python判断素数程序

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.

该程序将检查给定数字是否为质数 ，在此程序中，我们将数字从2除以该数的平方根，如果该数字除以b / w中的任何数字，则该数字将不是质数数。

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

我们正在使用类和对象的概念来实现该程序。

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

首先，我们使用Check名称创建具有1个属性( 'number' )和2个方法的Class，这些方法是：

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.

   构造方法 ：这是使用__init__内置关键字创建的。 构造函数方法用于在创建对象时初始化类的属性。

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.

   对象方法 ： isPrime()是对象方法，要创建对象方法，我们必须在函数创建时传递至少一个参数，即self关键字。

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，我们必须使用带有括号的类名来创建此类的对象，然后必须为其输出调用其方法。

Below is the implementation of the program,

下面是该程序的实现，

Python代码检查给定数字是否为质数 (Python code to check whether a given number is prime or not)

# Define a class for Checking prime numberclass 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())
