While I wait to find out what confuses you about the above, let me ask
another question that might get closer to the issue.

Would you find the following session confusing? Why?

    >>> a = "string1"
    >>> b = "string1", "string2"
    >>> c = "string1", "string2", "string3"

    >>> type(a)
    <class 'str'>
    >>> type(b)
    <class 'tuple'>
    >>> type(c)
    <class 'tuple'>

If the two examples give you different responses (one surprises you, the
other does not), I would really like to know *what the surprise is*.
What specifically did you expect, that did not happen?
