Passing a string to 'eval' is equal in having it as a part of an
expression, for example as having in at the right side of an assignment
operator (=), except for the quotes. The string returned happens to be
valid Python syntax: numbers seperated by comma's with ( and ) around it
create a tuple. It is valid to simply onter (1,2,3) at the Python
interactive interpreter: this is why it is valid to pass '(1,2,3)' to
eval. The result is the same.

Hope this helps,
yours,
Gerrit.
