将文件与zip列表进行比较，找出它是否很大

Question

我想比较两个zip文件夹的文件。 仅当大小更大时才复制当末尾已经有一个zip时如果缺少相等的名称，则复制文件。 只比较名称而不是日期：es-->；Campobasso[CB]-Molise

文件夹DirTemp ZIP: 坎波巴索[CB]-Molise_uuu02-02-2016.zip

文件夹DirArc ZIP: Foggia[FG]-Puglia\ u 22-01-2016.zip 罗马[RM]-Lazio\ U 20-01-2016.zip

文件夹dirarccartati， 它们是一个zip文件，如果找到了并且更小，就放在另一个文件夹中

这是我的代码，但工作部分，我不能复制文件（如果不存在）的末尾控制，与列表。你知道吗

以下方法可能更容易遵循：

def get_file_dictionary(folder):
    """ Return a dictionary of zip files in the given folder as tuples in the form: (basename, full path, size) """
    return {os.path.splitext(os.path.split(x)[1])[0].split('__')[0] : (x, os.path.getsize(x)) for x in glob.glob(folder + '*.zip')}

DirTemp = "/var/www/vhosts/italysat.eu/anon_ftp/incoming/"
DirArc = "/var/www/vhosts/italysat.eu/settings.italysat.eu/BackupDTT/"
DirArcScartati = "/var/www/vhosts/italysat.eu/settings.italysat.eu/BackupDTT_scartati/"    

incoming = get_file_dictionary(DirTemp)
existing = get_file_dictionary(DirArc)

for base_name_inc, (full_name_inc, size_inc) in incoming.items():
    try:
        full_name_exist, size_exist = existing[base_name_inc]

        if size_inc > size_exist:
            print "Transfer {} -> {}".format(full_name_inc, full_name_exist)
            os.remove(full_name_exist)
            shutil.copy2(full_name_inc, full_name_exist)
        else:
            discard = os.path.join(DirArcScartati, os.path.split(full_name_inc)[1])
            print "Discard {} -> {}".format(full_name_inc, discard)
            shutil.copy2(full_name_inc, discard)
    except KeyError, e:
        new_entry = os.path.join(DirArc, os.path.split(full_name_inc)[1])
        print "Transfer new {} -> {}".format(full_name_inc, new_entry)

    os.remove(full_name_inc)

它首先创建包含传入文件夹和存档文件夹中所有条目的字典。然后它遍历传入的字典以查看条目是否在存档中。如果是，则检查两个大小，如果不是，则复制新条目。你知道吗

字典以键为基本名称（不含日期）存储，值为完整路径名和文件大小。你知道吗
