Translating a Perl script into Python

[Emile van Sebille]

% based string formatting requires either a single argument,
or a tuple.  When using %(keyVal) substitution in the format
string, a single dictionary object may be used.  In this
case, only simple string keyVals are interpreted.
Otherwise, all single arguments must follow the type the %
substitution expected, ie %d accepts numbers, %s accepts
anything with a valid str/repr representation, etc.
