Anyone has a nice "view_var" procedure ?

Is there anything else than numbers ? ;-)
But indeed I forgot the else statement, which should look like this:
   else:
     line = 'UNKNOWN: ' + type(V)
     print line
     line = '  ' + V.__repr__()
     # do something to prevent too long output sequences
     print line

Thanks very much, that's almost perfect, I only had to change IndexError into KeyError.

I didn't succeed to use value as a enumerator, and I had to typecast key into a string (and skipping 
some redundant information, but then it works great, thanks !!
here the complete listing:
     count = {}
     for item in V:
       t = type(item)
       try: count[t] += 1
       except KeyError: count[t] = 1
     if type(V)==list: line = 'list:'
     else: line = 'tuple:'
     for key in count: line += '  %s=%d' %('N_'+str(key)[7:-2],count[key])
     print line
