Hi, there's a quick suggestion - the title of the issue should be more descriptive about the topic, rather than a very generic question, so the triagers and core devs can understand what's the issue about (whether it's in their area of expertise) without clicking into it.

cc @terryjreedy I don't understand the issue but since it seems to be IDLE related, I'm pinging you to have a look and decide the scope.

Which version of Python are you using? And what OS are you on?

On macOS I get:

Python 3.12.10 (v3.12.10:0cc81280367, Apr  8 2025, 08:46:59) [Clang 13.0.0 (clang-1300.0.29.30)] on darwin
Enter "help" below or click "Help" above for more information.
import help
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import help
ModuleNotFoundError: No module named 'help'

This is a subissue of #69674; I am leaving this open to patch this specific issue, which is that .../idlelib is sometimes on sys.path in the separate user process where user code is normally executed. ('Normally', means when option -n is not added to IDLE startup.) I noted in 2015 that this depends on how IDLE is started; and added today that it may have changed with version. It also depends the system. With 3.14 on my Win 10, >>> import help works. On my macbook with Catalina, it raises as Ronald shows above. (Note to anyone else: the splash line Enter "help" below ... is IDLE Shell specific.) Checking sys.path (most easily with for p in sys.path: print(p) shows that .../idlelib is present on Windows but not on Mac.

@Locked-chess-official What OS, python version, and IDLE startup method did you use.

I think adding the following to idlelib.run near the top should work.

for i in (0, 1):
   if sys.path[i].endswith('idlelib'):
    del sys.path[i]
    break

What OS, python version, and IDLE startup method did you use.

Windows, 3.12 and 3.13

When use idle.bat to start, it sames too.
