Error

OS: windows 10 pro
I am new to solidity and was following the tutorial video to install the solidity compiler. I successfully installed the solidity compiler.
However, when I tried doing the web3.py_simple_storage example I encounter this error:

INFO: Could not find files for the given pattern(s).

During handling of the above exception, another exception occurred:

Hello @samzyibia
Seems a problem with solcx compiler, I see you are using python v 3.10, could you please try using python v 3.9 or 3.8 (3.10 have been reported to have problems with web3 libraries) on a virtual env?

[samzyibia]

thanks let me try that

You have an unnecessary import, import solc just delete that line, you can always refer to the github repo as well ;)
