result = find_kth_prime(k) print(f"The {k}th prime number is {result}")运行结果如下：花了1.8秒 可以再测试一下，比如找第50000个质数，没优化的代码运行结果如下：优化后的结果如下：速度又一定的提升，但不明显 这还是质数本身的性质决定的，也就是：质数的分布是不规则的 我们...

If we find a factor in that range, the number is not prime, so we set flag to True and break out of the loop. Outside the loop, we check if flag is True or False. If it is True, num is not a prime number. If it is False, num is a prime number. Note: We can improve ...

使用Python计算前10000个质数表,质数也叫素数,是指大于1并且除了自己和1以外不能被其它整数整除的自然数。最近阅读《编程人生》,在书中看到了关于质数的描述,看《数学女孩》又看到了相应的描述。于是自己带着兴趣写了一段简单的Python代码求解出了前10000个质数。代码如

Prime Check Function (is_prime): This function checks if a number is prime by testing its divisibility from 2 up to the square root of the number. Main Function (print_first_10_primes): This function uses a while loop to find and print the first 10 prime numbers. It starts withnum =...
