如何计算出最接近的16:9宽高比分辨率。python 3

def calculate_nearest_resolution(width, height):
    target_ratio = 16 / 9
    target_width = width
    target_height = round(width / target_ratio)

    if target_height > height:
        target_height = height
        target_width = round(height * target_ratio)

    return (target_width, target_height)

# 示例用法
width = 1920
height = 1080
nearest_resolution = calculate_nearest_resolution(width, height)
print(f"The nearest 16:9 resolution for {width}x{height} is {nearest_resolution[0]}x{nearest_resolution[1]}")
