You are not entirely right. In python, one line means something as it is only one statement (as mentioned above). Author is also strict about not using eval -- with eval you could snuck multiple lines into one line (using \n in the evaluated string).
I'm not sure you can write function definitions, (nested) loops and other things that rely on indentation in single line using semicolons. At least I never managed to do that.

Last time when I used python I could separate statements with a semicolon and put as many as i want in a line. Did that change ? ;-)
This did not change, but the author also didn't use semicolons. As stated many times above, this is a single Python expression.

You can do it with lambdas, but it's going to be absurdly ugly: http://blog.sigfpe.com/2008/09/on-writing-python-one-liners....
