Yes,  this does the trick,   many thanks.

I used something like

import fnmatch as f
t = 'tim.williams'

# in place of  L = MyDict.keys()
L = ['tim*' ,  'dav* ',  'david' ,  'peter' ,  '*m' , '*y' , ' not-a-name ',
'timoth?' , '*.*' , '*iams' , '*']

L.sort()  # to give a consistent search order

for name in L:
...  if f.fnmatch(t, name):
...   print t, 'matches', name

tim.williams matches *
tim.williams matches *.*
tim.williams matches *iams
tim.williams matches tim*

:-)
