A use-case for for...else with no break

[Steve D'Aprano]

Occasionally it is useful to loop over a bunch of stuff in the interactive
interpreter, printing them as you go on a single line:

for x in something():
    print(x, end='')

If you do that, the prompt overwrites your output, and you get a mess:


py> for x in "abcdefgh":
...     print(x, end='')
...
py> efghpy>


"For ... else" to the rescue!

py> for char in "abcdefgh":
...     print(char, end='')
... else:
...     print()
...
abcdefgh
py>

enough, things got worse.
