I verified the Idle copy/cut context menu problem exists in macOS El Capitan
and macOS Catalina 10.15.4. It occurs in both the Shell and files.

Idle’s menu bar Edit -> Copy and Edit -> Cut options still work just fine. So
Idle is still very usable.
The keyboard shortcuts also still work:
<command>c == copy
<command>x == cut
So, there are multiple ways to copy/cut in Idle, even though there appears to
be a problem on the context menu.

No, Idle is not causing any problems in TextEdit, or any other editor. You may
not have BBEdit installed at the moment, but you (or someone else) installed it
sometime in the past. You are seeing detritus from that earlier deleted
installation. Idle knows absolutely nothing about BBEdit or any other editor
for that matter.
I also upgraded pip (both El Capitan and Catalina), but had no problems with it.
I didn’t reinstall the earlier version of Python, because the only problem with
Idle is the context menu.

I don’t know what you mean by “top panel”. Do you mean the macOS menu bar that
is displayed when you are using Idle or TextEdit?

No, it doesn’t “want” you to look up anything. When you highlight something in
TextEdit and use the context menu with it, one of the options is to look up
that selection in a dictionary. It’s there to make life easier for you — a lot
of folks like looking up word meanings. It’s totally up to you as to whether
you want to do that look up or not. In this case you selected the text
“System-Pc\Desktop\scene3…”, which is why that showed up in the context menu.
If you selected some other text, then it would show up in the context menu
instead of your earlier selection.

The only problem I saw was a minor issue with Idle’s copy/cut context menu
items.

On macOS the system uses Python 2.7. Therefore, if you install Python 3.x,
there will be two Python versions installed on your system. To make it easier
to use both versions:
“python”, “pip”, etc, without a version, runs Python 2.7.
“python3”, “pip3”, etc, runs Python 3.x. The exact 3.x.y version depends on
your PATH.
The documentation recommends invoking pip as a module on systems with multiple
versions installed, such as macOS:
