I think it was. I was puzzled as well.

But apparently if you have:

   x * = expr

That's like:

   x = x * (expr)        # note the parentheses

which may not always be the same as:

   x = x * expr

as the latter may depends on how operators within expr relate to the 
'*'. In your example, "/" within expr has the same precedence as "*" is 
the "*" is done first not last.

The type conversion may be another issue, but it doesn't explain why the 
results with the /same version/ of Python are different.
