In case you'd like to paste windows path from other source (say, File Explorer) - you can do so via input()
call in python console:
>>> input()
D:\EP\stuff\1111\this_is_a_long_path\you_dont_want\to_type\or_edit_by_hand
'D:\\EP\\stuff\\1111\\this_is_a_long_path\\you_dont_want\\to_type\\or_edit_by_hand'
Then just copy the result
