This is one area where Windows seems to do better than Linux shells:

PS C:\python33> python -c "import os`nfor root, dirs, files in os.walk('.'):`n    if len(dirs + files) == 1: print(root)`n"
.\Doc
.\Lib\concurrent\__pycache__
.\Lib\curses\__pycache__
...

The `n shell escaped newline is interpreted well before Python runs.

Also the multiline version works and in Powershell ISE up-arrow pulls it back as a 
single unit for easy editing:

PS C:\python33> python -c @"
import os
for root, dirs, files in os.walk('.'):
    if len(dirs + files) == 1: print(root)
"@
.\Doc
.\Lib\concurrent\__pycache__
.\Lib\curses\__pycache__
... and so on ...
