在目錄中查找重復文件和文件夾並將重復項移動到 python 中的不同文件夾

Question

我對 python 很陌生，我正在尋求幫助。 我正在嘗試在目錄中查找重復的文件夾和文件，並將它們移動到同一目錄中的不同文件夾（稱為Duplicates ），並在名為Single_Copy的文件夾中保留所有文件的單個副本。我能夠找到重復項和在 CSV 文件中添加他們的信息，但無法create文件並將其移動到 Duplicates 和 Single_Copy 文件夾。這段代碼沒有正確顯示重復的文件。請指導一下。 請在附件中找到我的一段代碼，

# checkDuplicates.py
# Python 2.7.6

"""

    """
    hash = hashlib.md5()
    with open(fname, "rb") as f:
        # Read the 1st block of the file
        chunk = f.read(chunk_size)
        # Keep reading the file until the end and update hash
        while chunk:
            hash.update(chunk)
            chunk = f.read(chunk_size)

    # Return the hex checksum
    return hash.hexdigest()

                md5_dict[generate_md5(file_path)].append(file_path)

    # Identify keys (checksum) having more than one values (file names)

        csv_writer = csv.writer(log, quoting=csv.QUOTE_MINIMAL, delimiter=",",

正如@Grismar 所說，您可以使用模塊os或shutil 。

import os
import shutil

os.rename("your/current/path/file.txt", "your/new/path/file.txt")
shutil.move("your/current/path/file.txt", "your/new/path/file.txt")

個人喜好： shutil ； 因為如果您在 windows 上，os.rename 將默默地替換具有相同名稱的現有文件。
