Note: We will be using Python 3.10 this semester with Wing 8 (or 9)! To activate Python 3.10 in the Wing IDE:

1. Select "Properties" from the "Project" menu
2. Check "Custom"
3. "Browse" to the Python 3.9 directory ("C:/Program Files/Python39" or "C:/Python39") and select the "python.exe" file
4. Click OK
