Python程序：求3到5之间的有理数

程序介绍

本程序是一个求解3到5之间有理数的Python程序，详细的介绍如下：

程序代码

def find_rational_numbers():
    """
    寻找3到5之间的有理数
    """
    result = []
    for i in range(1, 1000):
        for j in range(i + 1, 1000):
            if 3 <= i / j <= 5:
                result.append((i, j))
    return result

if __name__ == '__main__':
    numbers = find_rational_numbers()
    print('|数字|分数|')
    print('|---|---|')
    for num in numbers:
        print(f'|{num[0] / num[1]:.3f}|{num[0]}/{num[1]}|')

程序说明

1. 程序使用了双重循环进行遍历，遍历范围在(1,1000)之间
2. 遍历需要满足条件 $3\leq \frac{i}{j}\leq 5$
3. 将符合条件的有理数添加到一个结果列表中(result)
4. 最后将结果列表(result)格式化输出

输出结果
