So, the problem is that i am printing character using python's print() functions.
print("hello world \b\bs", end='', flush=True)
But it doesn't print hello worls rather it prints hello world.
I think "\b" makes the cursor go back one character and delete that one.
Above we have a space between 'd' of the 'world' and '\b\bs' that's why i used two backspace's.
Delete last printed character python above ans doesn't work!
