I was reading a tutorial that had these examples in it:
>>> while False:
print("False is the new True.")
>>> while 6:
print("Which numbers are True?")
while -1:
print("Which numbers are True?")
while 0:
print("Which numbers are True?")
Unfortunately the author never explained
Or should I have said While False is True, which is never True, because False
is False not True

Hi,
6, -1 or 0 are not bools (True or False):
>>> 6 is True
False
>>> 0 is False
False
If you had to design a language and want to think about using numbers
in a logical context you could do at least two things:
1) convert the number to bool, ie define a set of rules to assign to
each number a lo

That's usually a bad idea.
However, what you have not shown us is what you did
try that didn't work. (Unless thats what the snippet belo

You can test out a condition like this in IDLE like so:
while 6:
print "yes its true"
break
while 0:
print "yes its true"
break
while -1:
print "yes its true"
break
emptyList = []
while emtpyList:
print "yes its true"
break
This way you don't have to deal with

Of course that isn't very useful code. I thought it might be a useful
quick test for someone learning how while loops treat different
values.

In the simplest case, the webserver software executes your script.
Whatever you print() _is_ the webpage. The webserver sends whatever
you print() to the user's browser.

Whenever you're communicating to a web site, you are contacting a live
program, a "web server".
In typical usage, a web server delivers static files from its file
system. But it doesn't have to be that
