过滤整数数组中的所有素数

import math

def is_prime(num):
    if num < 2:
        return False
    for i in range(2, int(math.sqrt(num)) + 1):
        if num % i == 0:
            return False
    return True

def filter_primes(nums):
    primes = []
    for num in nums:
        if is_prime(num):
            primes.append(num)
    return primes

# 示例用法
nums = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
result = filter_primes(nums)
print(result)  # 输出: [2, 3, 5, 7]
