Python。 IOError：[Errno 13]权限被拒绝：当我复制文件时

Question

我有两个文件夹：In，Out - 它不是磁盘D上的系统文件夹： - Windows 7. Out包含“myfile.txt”我运行以下python命令：

>>> shutil.copyfile(r"d:\Out\myfile.txt", r"D:\In") 

Traceback (most recent call last): 
    File "<pyshell#39>", line 1, in <module> 
    shutil.copyfile(r"d:\Out\myfile.txt", r"D:\In") 
    File "C:\Python27\lib\shutil.py", line 82, in copyfile 
    with open(dst, 'wb') as fdst: 
IOError: [Errno 13] Permission denied: 'D:\\In' 

问题是什么？

Answer 1

阅读docs：

shutil.copyfile(src, dst)

Copy the contents (no metadata) of the file named src to a file named dst. dst must be the complete target file name; look at copy() for a copy that accepts a target directory path.

Answer 2

使用 shutil.copy代替shutil.copyfile

例如：

shutil.copy(PathOf_SourceFileName.extension,TargetFolderPath) 

Answer 3

井questionis老，为Python 3.6 的新观众使用

shutil.copyfile("D:\Out\myfile.txt", "D:\In") 

，而不是

shutil.copyfile(r"d:\Out\myfile.txt", r"D:\In") 

r参数传递读取文件不可复制
