Pyhton extension hangs when evaluting expression: undefined #659

1. Install the Microsoft Python extension
2. Debug the following python code:

for i in range(1,10):
    print(i)

3. Add a break point to the print statement
4. Try adding a variable in the watch window

Notice that vscode has an issue and that it sends an evaluate request to the python extension with expression: undefined. However the python extension never responds to this request and seems to be busy looping.

Note that the vscode insiders tomorrow will contain a fix on the vscode side. So maybe use this exact version https://az764295.vo.msecnd.net/insider/eed7e193125f3d4cfebe2089d1b2a9c674388754/VSCode-win32-x64-1.20.0-insider.zip
