[Tutor] dictionary swittching

[Raymond Hettinger]

Try changing all the 'elif' to 'if'.

Thanks for the replies, unfortunately none of the suggestions work. Actually
the snippet is for a CGI script that takes values from a form. I would like
different actions to be taken depending on the values of the keys:

##snippet


## below is used to convert the form output to a user friendlier dictionary
## code thanks to the python list

def FieldStorage2Dict(form):
    d = {}
    def decode_field(field):
      if isinstance(field, type([])):
        return map(decode_field, field)
      elif hasattr(field, "file") and field.file:
        return (field.filename, field.file)
      else:
        return field.value
    for key in form.keys():
      d[key] = decode_field(form[key])
    return d

formdict = FieldStorage2Dict(form)
#selector = ['agentnum','bnumber', 'tname', 'tvorname', 'tnumber',
'vnumber']
# these are the name values in the html form here just for clarity


if formdict.has_key('agentnum'):
  print 'test1'
elif formdict.has_key('bnumber'):
  print 'test2'
elif formdict.has_key('tname'):
  print 'test3'

##end snippet


sadly, only the first "if" works, I´m running Python 2.1.1 on a Wintel
machine

thanks
