Output and Clear Text in Terminal with Python

With the backspace sequence \b, you can erase printed characters.

print('requesting...', end='', flush=True)

heavy_method(...)...

print('\b' * 13, end='', flush=True)

When written with a context manager:

import contextlib


@contextlib.contextmanager
def print_and_erase(text):
    print(text, end='', flush=True)
    yield
    print('\b' * len(text), end='', flush=True)


with print_and_erase('requesting...'):
    heavy_method(...)
