# Program to check if a number is prime or not num = 29 # To take input from the user #num = int(input("Enter a number: ")) # define a flag variable flag = False if num == 0 or num == 1: print(num, "is not a prime number") elif num > 1: # check for factors for...
该函数接受一个参数n,然后使用一个计数器count来记录当前找到的质数个数,使用一个变量number来表示当前判断的数。在循环中,如果number是质数,则将count加1,直到count等于n时停止循环。最后,函数返回number-1,即第n个质数。 实例演示 让我们来使用nth_prime函数输出一些质数。 print(nth_prime(1))# 输出:2print(...
