Python 按从特定位置开始的时间间隔对图像进行分组

我有一个脚本，它从图像中获取exif数据，并将其放入列表中。然后我对我的清单进行排序，这就是我所拥有的。这是一个二维数组，其中第一个元素是时间戳，第二个元素是图像路径： 我的

img

列表：

[[32372, 'F:\\rubish\\VOL1\\cam\\G0013025.JPG'], 
 [32373, 'F:\\rubish\\VOL1\\cam\\G0013026.JPG'], 
 [32373, 'F:\\rubish\\VOL1\\cam\\G0013027.JPG'],.... etc etc etc

下面的脚本是由@blhsing和groups my images制作的。它工作得很好，但是我想把我的图片分组，不是从第一张图片开始，而是从任何给定的位置开始

这是@blhsing的脚本：

groups = []
for r in img:
    if groups and r[0] - groups[-1][-1][0] <= 5:
        groups[-1].append(r)
    else:
        groups.append([r])
for g in groups:
    print(g[0][1], g[0][0], g[-1][0], g[-1][1])

在本例中，我的

min_list

有两个位置，这意味着我只想创建两个组，并仅从这两个位置开始对图像进行分类，间隔与之前相同，为5秒

附言。 谢谢@pasch013它可以工作，但请检查一下，为什么结果是这样的，我从min_列表中得到mili如下：

min_list.sort()
print(min_list, " min list")
interval = 5
groups = []
#mili = [1, 99]
for start_time in min_list:
    i = 0

    while i < len(img) and img[i][0] < start_time:
        i += 1
    groups.append([])
    while i < len(img) and img[i][0] < start_time + interval:
        groups[-1].append(img[i])
        i += 1
    for ii in groups:
        print(ii[0][1], ii[0][0], ii[-1][0], ii[-1][1])

为什么我有3组而不是2组

现在正在正确创建第一组，但不想转到第二组，出现此错误

进程已完成，退出代码为1

请尝试：

group_time = 5
groups = []
mili = [1, 99]
for start_time in mili:
    i = 0

    while i < len(img) and img[i][0] < start_time:
        i += 1
    groups.append([])
    while i < len(img) and img[i][0] < start_time + group_time:
        groups[-1].append(img[i])
        i += 1

print(groups)

在内部for循环中，而我认为您只想打印一次。只需取消输入它们，它就可以按照您的需要工作：

min_list.sort()
print(min_list, " min list")
interval = 5
groups = []
#mili = [1, 99]
for start_time in min_list:
    i = 0

    while i < len(img) and img[i][0] < start_time:
        i += 1
    groups.append([])
    while i < len(img) and img[i][0] < start_time + interval:
        groups[-1].append(img[i])
        i += 1
for ii in groups:
    print(ii[0][1], ii[0][0], ii[-1][0], ii[-1][1])

第一个代码段的输出是什么？如果我运行它，我会得到没有任何意义的结果。
