How to flush entire row when printing status

Question

I have a code like this:

import time

print("some previous print", end='\r', flush=True)

for i in range(10):
    print("progress " + str(i), end='\r', flush=True)
    time.sleep(1)

The result is something like progress 9ous print - so it just cuts previous print by length.

I could have something like end=' \r' to make length longer, but not ideal and flexible solution. Any ideas?

@Pranav Hosangadi Exactly! Thank you. I wonder I have not found it myself (I was searching for a while). — Michal Palko, Feb 11 '22 at 21:20

To solve:

prepend an additional carriage-return (CR or \r) before the output-string
and make sure all previous printed characters are over-written (if necessary by space):

import time

print("About to start shortly.", end='\r', flush=True)
time.sleep(3)
print(" "*50, end='\r', flush=True) # overwritting a length of 50 with space

for i in range(10):
    print(f"\rprogress {i:2}", end='\r', flush=True)  # prefixed with CR, f-string right-aligned
    time.sleep(1)

Note: the status-lines have a constant width of 11 (9+ 2 digits reserved for the number, right-aligned).
