从 stu.txt 文件读取整数，轻松输出素数！附 Python 实现

```python def is_prime(num): if num < 2: return False for i in range(2, int(num0.5) + 1): if num % i == 0: return False return True with open('stu.txt', 'r', encoding='utf-8') as data: numbers = data.read().split() primes = [int(num) for num in numbers if is_prime(int(num))] for prime in primes: print(prime) ``` ######[AI写代码神器 | 133点数解答 | 2024-06-10 23:54:47]
