Hi all This is just out of curiosity.
I have a tuple, and I want to create a new tuple with a new value in the first position, and everything else unchanged. I figured out that this would work - >>> t = ('a', 'b', 'c') >>> t2 = ('x',) + t[1:] >>> t2 ('x', 'b', 'c') Then I thought I would neaten it a bit by replacing "('x',)" with "'x'," on the assumption that it is not necessary to surround a tuple with brackets. This is the result - >>> t = ('a', 'b', 'c') >>> t2 = 'x', + t[1:] Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: bad operand type for unary +: 'tuple' >>> It is not a problem - I will just stick to using the brackets. However, I would be interested to find out the reason for the error. Version is 2.6.2. Thanks Frank Millman -- http://mail.python.org/mailman/listinfo/python-list
