Miller-Rabin算法是一种随机算法，通过进行多次的素性判断，可以更加准确地判断素数。Miller-Rabin算法的代码示例：import randomdef is_prime(n, k=5):(tab)if n <= 1:(tab)(tab)return False(tab)if n <= 3:(tab)(tab)return True(tab)if n % 2 == 0:(tab)(tab)return False(tab)def check(...
Python program to check prime number using object oriented approach# 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(...
def CheckPrime(self, a): for i in range(a): if (a % i): return False return True def CalcFact(self, a): if (a == 1): return a else: return a * self.fact(a-1) 上面的代码包含了两个函数CheckPrime和CalcFact,根据它们的名称可以看出它们检查素数和计算阶乘。
def check_prime(num):if num == 2:return True for i in range(2,int(num)):if num % i == 0:return False return True # 输入一个整数 number = int(input())# 调用函数 print(check_prime(number))3、代码分析：注意考虑2这种特殊情形；素数又称质数，是指在大于1的自然数中，除了1和它本身...
可惜,from是Python的关键字,一回车它就报错了。因此,将其改为checkPrime(start, end)。然后输入下图中所示的函数实现代码并调用checkPrime(1, 100)。其中用到的内建函数range(),用于返回一个按指定步长增长的列表,因此可以与for..in语句配置使用(注:print()函数中可以传入多个参数,它们会在同一行中顺次显示);...
