paseline(my favorite simple script): does something similar exist?

Untested, but maybe more in current Pythonic style:

 def parseline(line,format):
     xlat = {'x':None,'s':str,'f':float,'d':int,'i':int}
     result = []
     words = line.split()
     for f,w in zip(format, words):
        trans = xlat[f]
        if trans is not None:
           result.append(trans(w))
     return result

Differences:
  - doesn't ignore improper format characters, raises exception instead
  - always returns values in a list, including as an empty list if
    there's no values
  - uses iterator protocol and zip to avoid ugly index variable
    and subscripts
