def format(values, format):
   formatlist = format.split(',')
   sf = ''
   for formatitem in formatlist:
     type = formatitem[0]
     if type in 'fi':
       sf += '%' + formatitem[1:] + type
     if type == 'a':
       sf += ' '*int(formatitem[1:])
     elif formatitem[-1] == 'x':
       sf += '%' + formatitem[:-1] + 's'
   return sf % values
a = 5
alf = 'qwer'
i = 3
print format((a, alf, i), "f10.2,a10,10x,i5")

result:       5.00                qwer    3

For simplicity I removed the spaces between the fortran format items. A 
little more code would handle them.
