How to print iterated strings in same lane of stdout (Windows cmd)?

Question

I am using following code to display string with loop completition percentage:

for x in range(y,z):
    completed = 100*(x-y)/(z-y)
    sys.stdout.write(f'{completed:10.0f}% completed.'
    sys.stdout.flush()

And I want all the strings to be displayed in the same line of windows cmd (earlier value removed, and new printed in same place)

Output I want to obtain, should look like this:

    x% completed.

Where x value is updated with each iteration.

But the output i get looks like this:

    0% completed.         1% completed.         2% completed. ...etc

From what i found it should work on other platforms than Windows, but I am interested about Windows solution.

add \r at the end of the string:

for x in range(y,z):
    completed = 100*(x-y)/(z-y)
    sys.stdout.write(f'{completed:10.0f}% completed.  \r'
    sys.stdout.flush()

unless you have some buffering issues you should be able to use print directly:

for x in range(y,z):
    completed = 100*(x-y)/(z-y)
    print(f'{completed:10.0f}% completed.  ', end='\r')
