Python. IOError: [Errno 13] Permission denied: when i’m copying file

I have two folders: In, Out – it is not system folder on disk D: – Windows 7. Out contain “myfile.txt” I run the following command in python:

>>> shutil.copyfile( r"d:Outmyfile.txt", r"D:In" )

Traceback (most recent call last):
  File "<pyshell#39>", line 1, in <module>
    shutil.copyfile( r"d:Outmyfile.txt", r"D:In" )
  File "C:Python27libshutil.py", line 82, in copyfile
    with open(dst, 'wb') as fdst:
IOError: [Errno 13] Permission denied: 'D:\In'

What’s the problem?

Answer

Read the 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.
