Matplotlib is downloaded but IDLE says it is not installed

I have matplotlib downloaded and installed but IDLE says it is not available.
I do have screenshots of my struggle with this.

I do not understand what is going wrong.

I have matplotlib downloaded and installed but IDLE says it is not
available.
I do have screenshots of my struggle with this.

These 2 screenshots would go better as text pasted inline, eg:

 ```
 pasted output

 ```

More legible and lets us copy/paste as text if that’ useful.

Anyway,…

I do not understand what is going wrong.

You seem to have 2 different Pythons installed. The pip command
appears to be installing in a Python 3.10 install. Your IDLE seems to be
running 3.9.1. These have distinct install areas.

You need to install matplotlib in the Python which IDLE is using.

If necessary you can do this from inside Python by using the pip
module:

 import pip
 pip.main(['help'])
 pip.main(['install', 'requests'])

That:

• imports the pip module
• prints its help, like the command pip help
• installs the requests module, like pip install requests

In a way this is the recommanded way to use pip: instead of running
the pip command, run these desired Python and use its pip module. As
an example command:

 python -m pip install matplotlib

(Adjust for python to suit.) This ensures that you’re using the pip
for that particular Python. The IDLE example above inherently uses the
Python which IDLE is using, because you’re importing its pip and
installing with that.
