Hi all,
What's wrong with the following code? It says there is name error, that
random is not defined. How do I fix it?
# Plays the guessing game higher or lower.
# Originally written by Josh Cogliati, improved first by Quique, then by
Nathan Pinno.
print "Higher or Lower"
print
number = random.choice(range(100))
guess = 0
while guess != number:
guess = input("Guess a number: ")
if guess > number:
print "Too high"
guess = input("Guess a number: ")
elif guess < number:
print "Too low"
guess = input("Guess a number: ")
print "Just right"
Thanks.

Add "import random" at the top of your file
Cheers,

You need to import random.

There is a problem with this, caused by having to repeat the same code in
multiple places. Sa that the number is 50. You get to the first "input"
statment, and you enter 30. It prints "Too low", and asks you to enter
another number. You enter 40. The "while" expression is true, so it will
loop again, and prompt you to enter ANOTHER number, without telling you
whether it was high or low.
Better to eliminate duplicated code:
import random
print "Higher or Lower"
print
number = random.choice(range(100))
while 1:
guess = input("Guess a number: ")
if guess == number:
break
elif guess > number:
print "Too high"
else:
print "Too low"
print "Just right"

Others have already answered that question. This posting is a
pre-emptive strike to head off the next half-a-dozen questions. # Plays the guessing game higher or lower. # Originally written by Josh Cogliati, improved first by Quique, then by Nathan Pinno.
Some of us are interested in the process by which great pieces of code
arise, how they are meticulously honed and polished, which craftpersons
contributed what ... is it possible for you to publish the earlier versions?
print "Higher or Lower" print number = random.choice(range(100))
"number" will refer to one of: 0, 1, ......, 98, 99
guess = 0
so you'll get a strange result by using zero here; try -1 instead
while guess != number: guess = input("Guess a number: ")
"guess" will refer to a string e.g. "42" which will *not* compare equal
to the integer 42. Also you should use raw_input, not input.
so do this:
guess = int(raw_input("Guess a number: "))
if guess > number: print "Too high" guess = input("Guess a number: ")
This will cause your program to ask TWICE per trip around the loop. Lose it.
elif guess < number: print "Too low" guess = input("Guess a number: ")
.... and again.
print "Just right"
General advice:
1. Look on the Python web site ( http://www.python.org) for an
introduction to Python for non-programmers.
2. Join the Python tutor list.
3. In this news group, read a little more than the threads that you have
started; this guessing game was discussed in a thread started by
somebody calling themselves ChuckDubya on 29 June!! Homework??
HTH,

Ahem ... I'll redo that:
You'd be better using raw_input, which *then* means you need to wrap
int() around it, ending up with the same recommendation:
guess = int(raw_input("Guess a number: "))
