3 Actions:
|
|
|
4
|
|
|
5 1. Remove our entries from the Registry:
|
|
|
6 - Software\Python\PythonCore\<winver>
|
|
|
7 - Software\Microsoft\Windows\CurrentVersion\Uninstall\Python<winver>
|
|
|
8 (Should we also remove the entry for .py and Python.Script?)
|
|
|
9
|
|
|
10 2. Remove the installation tree -- this is assumed to be the directory
|
|
|
11 whose path is both os.path.dirname(sys.argv[0]) and sys.path[0]
