根据名称对填充物进行排序

如何解决根据名称对填充物进行排序

我正在使用 Python 脚本（在 macOS Mojave 上使用 Python 2.7），它会列出目录中存在的文件，然后对它们进行一些操作。这是 12 个 DLG 文件在 workdir 中的排列方式：

(base) Glebs-MacBook-Pro:1200_cne_lig177 gleb$ ls -t
1200_01_lig_cne_177.dlg 1200_05_lig_cne_177.dlg 1200_09_lig_cne_177.dlg
1200_02_lig_cne_177.dlg 1200_06_lig_cne_177.dlg 1200_10_lig_cne_177.dlg
1200_03_lig_cne_177.dlg 1200_07_lig_cne_177.dlg 1200_11_lig_cne_177.dlg
1200_04_lig_cne_177.dlg 1200_08_lig_cne_177.dlg 1200_12_lig_cne_177.dlg

这是从这些 DLG 文件中生成列表的 python 脚本的一部分：

    # make a list of dlg filles
dlg_list = glob.glob(directory + '/*.dlg'
print(dlg_list)

d = Docking()
# doing something on DLG
for dlg in dlg_list:
        d.readDlg(dlg)

这是从 glob 中获取的文件列表，同时调用变量 dlg_list：

['/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_04_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_12_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_03_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_02_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_05_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_07_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_11_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_08_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_06_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_10_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_09_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_01_lig_cne_177.dlg']

可以看出，DLG文件的编号（每个文件名中7000_后的数字）为：1200_04_、1200_12_、1200_03_、1200_02_、等，与自然顺序1200_01_、1200_02_、1200_03_、1200_04_等不匹配。

之前，我使用旧版本的 macOS (El Capitan)，并使用完全相同的 Python 版本运行相同的脚本，使此列表以从 01 到 12 的正确方式对 DLG 文件进行排序。

如果 OSX 和全局排序的工作方式不同，我无法解释为什么会发生这种情况。如何解决 glob 的问题？

解决方法

您可以对 dlg_list 进行排序。

例如：

dlg_list = [
    '/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_04_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_12_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_03_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_02_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_05_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_07_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_11_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_08_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_06_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_10_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_09_lig_cne_177.dlg','/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_01_lig_cne_177.dlg',]

sorted_dlg_list = sorted(dlg_list,key=lambda x: x.rsplit("/")[-1].split("_")[1])

for item in sorted_dlg_list:
    #  do your stuff here
    print(item)

输出：

/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/7000_cne_lig177.AllBoxes/7000_01_lig_cne_177.dlg

您可以在str.split()方法的自定义键中使用sorted()方法：

sorted(dlg_list,key=lambda x: x.split("_")[-4])
