I just spent a while beating my head against this one.
# Python 2.6
>>> a, b = 'foo'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: too many values to unpack
The real problem is that there's too *few* values to unpack! It should
have been
a, b = 'foo', 'bar'
I understand why it's generating the exception it does (the string is an
iterable), but man, did that message throw off my thought processes and
lead me down some totally bogus debugging paths.
It's an unusual case to want to unpack a string. Maybe the message
should changed to "too {many, few} values to unpack (are you sure you
wanted to unpack a string?)" if the RHS is a basestring?
