@B4B Not for you, you're a moderator :)

Thank you so much!

Try googling it.

if the \n at the end of each line is not guaranteed

Description doesn't say that. Description says this:

track - string representation of the entire train line (\n separators - maybe jagged, maybe not trailing)

• \n separators - means each row is separated by \n
• maybe jagged - means each row might be different lengths
• maybe not trailing - means the \n of the last row is optional

no the linefeed are always present. That's the number of trailing spaces, hence, the length of the row, that isn't guaranteed.

Happy coding ^_^

I've tested the same solution code of mine for Python 2.7.6 and Python 3.4.3 just now and both pass all final test cases. I think there is no issue if you aren't using version-specific stuff.

Happy coding ^_^

Fixed all the above (and more :-)

and note that the function name should be written in snake_case, not camelCase

You could improve the random tests, to guarantee some flushes.

Oh good, so I can stop wasting time on it then. Unfortunately, my solution uses a lot of Python 3-specific things, so I need to decide between rewriting most of it or simply waiting a few years for someone to get around to fixing it.

Thankyou, I had this exact same issue, my solution wouldn't work in 3.4.3 but does in 2.7.6 and works in my python 3.6.2 IDLE environment.

Yes, but already too many completions, tests are locked...

Thanks!! :)
