When I publish my azure cloud functions I get the message:

Local python version '3.9.7' is different from the version expected for your deployed Function App. This may result in 'ModuleNotFound' errors in Azure Functions. Please create a Python Function App for version 3.9 or change the virtual environment on your local machine to match 'Python|3.8'.

How can I change the version to 3.9?

You can view and set the linuxFxVersion from the Azure CLI.
With the az functionapp config set command, you can change the linuxFxVersion setting in the function app.

az functionapp config set --name <FUNCTION_APP> --resource-group <RESOURCE_GROUP> --linux-fx-version "PYTHON|3.9"

Please refer Changing Python version for more information.

I have the same issue, but I do not have the permission to update config(to python3.9). So I try to install python3.7. And run deployment with func azure functionapp publish <func_name> --publish-local-settings -i --overwrite-settings -y --python. Same error occurred. I also got this error message "Unexpected character encountered while parsing value: {. Path '[0].build_summary', line 1, position 663." Any suggestions?
I'm getting '3.9' is not recognized as an internal or external command, operable program or batch file.

For those of you facing the following error when attempting the solution provided by Harshitha:

'3.9' is not recognized as an internal or external command,

operable program or batch file.

This is because '|' needs to be escaped within the string "PYTHON|3.9" to work in PowerShell. This will work:

'Python"|"3.9'
