Another stupid newbie question

[Byte]

How can I make the following code:

from random import random



def stuff(a, mx):
x = 2
while x == 2:
x = random()
if x == mx: print x
else: print 'No luck,', x
x = 2

Stop when x == mx?

Thanks in advance,

How can I make the following code:

from random import random



def stuff(a, mx):
x = 2
while x == 2:
x = random()
if x == mx: print x
else: print 'No luck,', x
x = 2

Stop when x == mx?

What's the intention behind setting x = 2 at all?

def stuff(a, mx):
while True:
x = random()
if x == mx: print x
else: print 'No luck,', x

Should do the same as you're code above.

If stuff will never be called with mx=None, I would suggest using

def stuff(a, mx):
x = None
while x != mx:
x = random()
if x == mx: print x
else: print 'No luck,', x

Also note that random() returns a float and it is *very* unlikely that the
condition x == mx will ever come true

Right! And as for stopping use 'return' after your print statement to
exit.

Great, thanks all. Now, how come

if x == mx: print x
break

Dosnt work?

If you have a suite with more than one line, you must put it on a new line.

if x == mx:
print x
break

Perhaps it would be good for you to work through the Python Tutorial.

Great, thanks all (the point of x = 2 was that i dont understand
exactly what True is on while True

I find that webpage highly insulting, and so should you. It is treating
you like a small child, who needs to be told everything. If you need
more information, just ask. I myself have been on hardware lists/fourms
for quite a while now. I never answer questions that go into too much
detail, I find it off-putting and insulting - I feel it treats me like
some sort of robot, that requires all eventualities to be programed
into it to start answering the questions. I just ask politly for more
info, if I need it. But questions from people saying 'Please help' etc.
is great. They know they are in the wrong, and intend to be humorus.
They dont intend to annoy/offend anybody. And really, I dont need to be
told how to be polite, thank you. As regards to grammer/spelling, what
if sombody is unsure of how to spell something? And did you ever hear
of being in a rush?
