What is a Prime Number in Python? A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. For example, the numbers 2, 3, 5, 7, 11, and 13 are prime numbers because they have no divisors other than 1 and themselves. Print P...
下面的 Python 代码展示了如何实现埃拉托斯特尼筛法。我们将创建一个函数来返回 n 以内的所有素数。 defsieve_of_eratosthenes(n):# 创建一个布尔列表,初始时所有数都标记为素数is_prime=[True]*(n+1)p=2while(p*p<=n):# 如果 is_prime[p] 为 True,则 p 是一个素数ifis_prime[p]:# 更新 p 的倍数...
defnth_prime(n):count=0number=2whilecount<n:ifis_prime(number):count+=1number+=1returnnumber-1 1. 2. 3. 4. 5. 6. 7. 8. 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...
