Anyone has a nice "view_var" procedure ?

It appears that you're a number crunching guy - you absolutely ignore 
all types except numeric ones! :)

I don't understand this, but if you are saying that you can't get the 
name of the variable you're showing - just pass the name to the 
function: def pm(V, name)

Ouch, seven counters... your guts should be saying that this is 
candidate for a more structured type... what about a dictionary 
indexed by the element type?

      count = {}

You're going to iterate along all the items in V, not along its indices...

Using a dict:

      for item in V:
         t = type(item)
         try: count[t] = count[t]+1
         except IndexError: count[t] = 1

(That is: if the type is found in the dictionary, increment the 
count; if not, this is the first time: set the count to 1)

We'll replace all of this with:

      for key,value in count:
         line += ' %s=%d' % (key, value)

      if len(count)==1: line += '  == Homogeneous =='
