    why did the last line get the correct output, and the others didn't?

    When you print foo, what gets printed out is str(foo).

    However, if foo is a list, str(foo) uses repr(bar) for each element bar, not str(bar).

    The str of a string is the string itself; the repr of a string is the string inside quotes, and escaped.

    how do I correct the wrong ones

    If you want to print the str of every element in a list, you have to do that explicitly. For example:

    print '[' + ', '.join(["asdf", "中文"]) + ']'
    

    There have been sporadic proposals to change this behavior, so str on a sequence calls str on its members. PEP 3140 is the rejected proposal. This thread from 2009 explains the design rationale behind rejecting it.

    But primarily, it's either so these don't print the same thing:

    a = 'foo, bar'
    b = 'foo'
    c = 'bar'
    print [a]
    print [b, c]
    

    Or, paraphrasing Ned Batchelder: repr is always for geeks; str is for humans when possible, but printing lists with their brackets and commas is already for geeks.
