Question

我正在尝试编写一个简短的Python脚本，该脚本将从具有特定扩展名的目录中复制所有文件，并将它们放在不同的文件夹中。这是脚本：

import os, shutil

source = "C:\\TCR_Calgary\\projects\\"

destination = "C:\\TCR_Calgary\\reference\\my_code\\city_of_calgary_scripts\\"

extension = ".py"

for root, dirs, files in os.walk(source):
    for file in files:
        if file.lower().endswith(extension):
            shutil.copy2(file, destination)

这是我得到的例外：

Traceback (most recent call last):
  File "C:/TCR_Calgary/reference/my_code/city_of_calgary_scripts/python_script_copier.py", line 13, in <module>
    shutil.copy2(file, destination)
  File "C:\Program Files (x86)\Python26\lib\shutil.py", line 99, in copy2
    copyfile(src, dst)
  File "C:\Program Files (x86)\Python26\lib\shutil.py", line 47, in copyfile
    raise Error, "`%s` and `%s` are the same file" % (src, dst)
shutil.Error: `AnnoMover.py` and `C:\TCR_Calgary\reference\my_code\city_of_calgary_scripts\AnnoMover.py` are the same file

我很困惑，因为AnnoMover.py不在目标文件夹中。在我看来，原始文件及其副本将是相同的＆＃34;虽然他们的路径不会。很明显，我在这里并不理解。非常感谢任何帮助！

Answer 1

异常消息可能更清楚一点，但最后一行应为shutil.copy2(os.path.join(source, file), destination)，以便源完全合格。

Answer 2

我得到了它的工作：

import os, shutil

source = r"C:\TCR_Calgary\projects"

destination = r"C:\TCR_Calgary\reference\my_code\city_of_calgary_scripts"

extension = ".py"

for root, dirs, files in os.walk(source):
    for file in files:
        if file.lower().endswith(extension):
            file_path = os.path.realpath(os.path.join(root, file))
            shutil.copy2(file_path, destination)

复制文件时出错
