The end parameter of print is a Python 3 feature - only possible
because print is now a function rather than a command.
In Python two the only option was to add a comma at the end
of the print statement qwhich suppressed the newline.
But the end parameter allows you to add anything you like,
not just newlines or a null.. Of course you can use string
formatting in Python 2 to achieve similar results.
The if construct is nothing to do with print, it is a standard
conditional expression introduced in Python v2.5 or 2.6?
As is true of any *expression* it can be used anywhere
that a value is used. This is because every expression
produces to a value.
So in Python v2 we could simulate Steven's loop with:
for n in range(3):
s += "%d spam%s" % (n,"\n" if n==3 else "***")
print s, # comma to avoid print adding its own \n...
But the print(..., end=....) version is much prettier IMHO.
