But what about
>>> '%(name)s was born in %(country)s' % {'name':'Guido',
'country':'the Netherlands'}
'Guido was born in the Netherlands'
>>> name = 'Martin'
>>> country = 'Sweden'
>>> '%(name)s was born in %(country)s' % globals()
'Martin was born in Sweden'
What's the advantage of using ${name} and ${country} instead?
/Martin
