Ouch. I hope it paid well. ;)
Back when I did a lot of TeX/LaTeX stuff on VMS, I used to make
occasional fixes and add (very minor) features to one of the dvi

hidden ways too. There are no promises of purity.
What this particular discussion began with was much lower level and about
various ways of writing a while loop within very basic Python and seems to
be heading away into discussions of other

If you want to terminate the script you can use exit. However exit is a

Am I unreasonable in expecting this code to exit when required?
# Add up the powers of 2 starting with 2**0 until 2 million is met.
n = 1
target = 200
sum = 0
while True:
x = 2 ** (n - 1)
sum += x
print(n, sum)
if sum >= target:
print("Target met.")
exit
tion.
At least the title of the post: "How can i stop this Infinite While
Loop" is descriptive. Compared with some first-time poster's titles,
this is clear and competent. Thanks!
Thinking about it though, is there a hint of the nature of the problem,
or even then an answer, in t

That's the (in)famous "off by one"

If you try this in the REPL, you'll see that 'item' is a string. You're
trying to compare it to an integer, which will always fail.
The cheapest way to fix this is probably:
if item != '-1':

If so, you need to check if item is -1 or total tries are already 10 and in
such a case break the loop.
No need for an else branch.
Note, input returns an str object but you compa

But with 'else', if you see the message it means the while statement has
been entered. Here:

while n>=x:
n=n-1
print "*"* n
else:
print ("2nd loop exit n=",n,"x=",x)

It's a basic fact about while loops that after the loop the condition is
false. The two conditions x <= n a

Did you try printing out the loop variable to see what it does and what

Because after the first loop n < x
