我在 os.

推荐答案

shutil 有很多方法可以使用.其中之一是:

shutil has many methods you can use. One of which is:

from shutil import copyfile
copyfile(src, dst)

# 2nd option
copy(src, dst)  # dst can be a folder; use copy2() to preserve timestamp

• 将名为 src 的文件的内容复制到名为 dst 的文件中.src 和 dst 都需要是文件的完整文件名，包括路径.
• 目标位置必须是可写的；否则，将引发 IOError 异常.
• 如果 dst 已经存在，它将被替换.
• 无法使用此功能复制字符或块设备和管道等特殊文件.
• 对于copy，src 和dst 是以strs 给出的路径名.
• Copy the contents of the file named src to a file named dst. Both src and dst need to be the entire filename of the files, including path.
• The destination location must be writable; otherwise, an IOError exception will be raised.
• If dst already exists, it will be replaced.
• Special files such as character or block devices and pipes cannot be copied with this function.
• With copy, src and dst are path names given as strs.

另一个要查看的 shutil 方法是 shutil.copy2().它很相似，但保留了更多元数据(例如时间戳).

Another shutil method to look at is shutil.copy2(). It's similar but preserves more metadata (e.g. time stamps).

如果您使用 os.path 操作，请使用 copy 而不是 copyfile.copyfile 只接受字符串.

If you use os.path operations, use copy rather than copyfile. copyfile will only accept strings.
