Summary: Bad RE in scanf example

Initial Comment:
In section 4.2.6 "Examples" of the Python Library

Reference, the regular expression for scanf format

tokens %e, %E, %f, %g does not allow an optional sign

in the exponent.  The RE should be:



  [-+]?(\d+(\.\d*)?|\d*\.\d+)([eE][-+]?\d+)?

Double-checking with K&R, Jimm is right and regex looks good to 

me.  Hope that helps in some way, Raymond.
