Are you sure? Is that a cut n paste or just how you think you remember
it? The reason i ask is that its not what i see and not what I'd expect.
In Python v2 print is a statement which means that Python sees your
first print line like:
print (" Welcome to Squid Monitoring for ", "10.41.17.237")
That is it thinks you want it to print a tuple of 2 strings and what I
see as output is:
(' Welcome to Squid Monitoring for ', '10.41.17.237')
Which is a tuple of 2 strings...
Now if I remove the parentheses it looks like:
print " Welcome to Squid Monitoring for ", "10.41.17.237"
Which is telling Python to print two strings joined by a space.
And I see the output:
Welcome to Squid Monitoring for 10.41.17.237
And in both cases the second print just prints out an empty
string with no quotes.
Are you sure that's not what you saw?

In Python 3 print is a function so it needs the parentheses.
Without them it will report a syntax error. So for Python 3
your original code is correct.
