What do you expect as result of this combination of an integer with a
string?
>>> a = 5 '''a comment'''
File "<stdin>", line 1
a = 5 '''a comment'''
^
SyntaxError: invalid syntax
You may use an *, and you buid a valid expression with a result
>>> a = 5 * '''a comment'''
But… this may not be the value you wanted for a variable.
>>> a
'a commenta commenta commenta commenta comment'
So, a string is really not a comment, even if triple quote strings can be
used alone to store multi-line "comments".
