在python中使用带有大小写不敏感的endswith

Question

我有一个文件扩展名列表,我必须写条件.就像是

ext = (".dae", ".xml", ".blend", ".bvh", ".3ds", ".ase",
           ".obj", ".ply", ".dxf", ".ifc", ".nff", ".smd",
           ".vta", ".mdl", ".md2", ".md3"
           ".pk3", ".mdc", ".x"
           ".q3o", ".q3s", ".raw"
           ".ac", ".dxf", ".irrmesh"
           ".irr", ".off", ".ter"
           ".mdl", ".hmp", ".mesh.xml"
           ".skeleton.xml", ".material", ".ms3dv"
           ".lwo", ".lws", ".lxo"
           ".csm", ".cob", ".scn"
           ".xgl", ".zgl")
for folder, subfolders, filename in os.walk(directory):
    if any([filename.endswith(tuple(ext)) for filename in filenames]):

我意识到endwith是区分大小写的.例如,我可以将".xml"和".XML"视为相同的扩展名吗？

lower在调用之前,只需调用使字符串为小写endswith:

ext = (".dae", ".xml", ".blend", ".bvh", ".3ds", ".ase",
           ".obj", ".ply", ".dxf", ".ifc", ".nff", ".smd",
           ".vta", ".mdl", ".md2", ".md3"
           ".pk3", ".mdc", ".x"
           ".q3o", ".q3s", ".raw"
           ".ac", ".dxf", ".irrmesh"
           ".irr", ".off", ".ter"
           ".mdl", ".hmp", ".mesh.xml"
           ".skeleton.xml", ".material", ".ms3dv"
           ".lwo", ".lws", ".lxo"
           ".csm", ".cob", ".scn"
           ".xgl", ".zgl")
for folder, subfolders, filename in os.walk(directory):
    if any([filename.lower().endswith(tuple(ext)) for filename in filenames]):
