Formatting Strings in Python [duplicate]

Question

I'm printing a title in python and I want it on the center of the screen. I know I can do it by using

"{:^50}".format("Title")

But the thing with this command is it only utilizes the width I give in (in this case, 50). But it isn't perfect and is sometimes way off. Even if I approximate the width by observing/guessing, it would go out of format if I re-size the terminal. I always want to align it on the middle of the screen, even when the terminal is re-sized(say, in fullscreen mode). Any ways I can achieve this?

EDIT: I have did this: Well, I figured out the way to find the window size,

import os
columns = os.popen('stty size', 'r').read().split()[0]
"{:^"+columns+"}".format("Title")

but the last line shows error. I finally have the window size, but I cannot format it correctly. Any help is appreciated!

As zondo pointed out, the title won't reposition when the window is resized.

The correct way to do this: "{:^"+columns+"}".format("Title") is like so:

"{:^{}}".format("Title", width)
#^---------------^ first argument goes with first brace
#   ^--------------------^ second argument goes with second brace and sets the width
