PrimeFunctionIsPrimeFunctionUserPrimeFunctionIsPrimeFunctionUser请求获取素数列表调用判断素数返回结果返回素数列表 结论 通过本文,我们实现了isprime和prime函数,并通过测试验证它们的正确性。isprime函数用于判断单个数字是否为素数,而prime函数则用于生成一定范围内的所有素数。掌握这两个函数后,你可以在 Python 中更灵活地处...

def isPrime(num): # Return True if num is a prime number. This function does a quicker # prime number check before calling rabinMiller(). if (num < 2): return False # 0, 1, and negative numbers are not prime. 当num不小于2时,我们也可以使用LOW_PRIMES列表作为测试num的快捷方式。检查nu...
