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?
