I did as written here, but it doesn't work yet.
Please tell me what else can be done.

the Error is: PermissionError: [Errno 13] Permission denied: 'C:\\ProgramData\\Microsoft\\Windows\\Start Menu\\Programs\\StartUp\\IP.PY'

This is my code:
import shutil
original = r'C:\Users\Руслан\Desktop\HACKPROG\IP.PY'
target = r'C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp'
shutil.move(original,target)
and I am getting the following Error:
During handling of the above exception, another exception occurred:

You don't appear to have permissions to write to the Start Up folder.
You can fix this by running your Python terminal as an administrator (right click IDLE/cmd and press run as administrator).

you can run this program in 2 ways
Method 1:
Add python to path, By editing environmental variables.
Method 2:
Open console/cmd . Direct path to python file by
cd C:\\ProgramData\\Microsoft\\Windows\\Start Menu\\Programs\\StartUp
And then after entering directory
python ip.py --user

Permission denied by shutil.copy() when copying a directory instead of a file

This is the code I executed:
shutil.copy(r'd:\try',r'd:\new')
The output I got was:
Traceback (most recent call last):
File "<pyshell#9>", line 1, in <module>
shutil.copy(r'd:\try',r'd:\new')
File "C:\Users\Username\AppData\Local\Programs\Python\Python38-32\lib\shutil.py", line 415, in copy

with open(src, 'rb') as fsrc, open(dst, 'wb') as fdst:
PermissionError: [Errno 13] Permission denied: 'd:\\try'
I get this permission error only when I try to copy folders but this error doesn't occur when I copy a file. How to fix this?

As can be read in the documentation, shutil.copy() is used for copying files.
To copy a directory, use shutil.copytree() instead:
shutil.copytree(r'd:\try', r'd:\new')

How can I resolve it?

Shelve Module Not Working

After I reinstalled Python to move it from an AppData folder to Program Files, it looks like the shelve module is no longer working and I receive the error below when I call upon shelve.open().
Please help!
>>> import shelve
>>> myShelf = shelve.open('data')
Traceback (most recent call last):
File "C:\Program Files\Python\lib\dbm\dumb.py", line 81, in _create
f = _io.open(self._datfile, 'r', encoding="Latin-1")

>>>

The error "FileNotFoundError: [Errno 2] No such file or directory: 'data.dat'" shows you, it can not find the data.dat, please check the file location.

I had this problem using Windows 10. I solved the issue by changing the working directory to a folder under my profile.
os.chdir('C:\\Users\\Nat\\Documents\\Python\\Project 1')
I presume I didn't have permission to write a file 'Program Files'.
