Removing "U" flag as it is removed from Python3.11!

"U" flag was deprecated since Python3.3 but has been removed from Python3.11. This "universal newline" mode is by default enabled whenever a file is opened in text mode. For reference : https://docs.python.org/3/whatsnew/3.11.html Signed-off-by: Anushree Mathur <[email protected]>
