Hi all -
Just started on "Python Programming for Absolute Beginners" and I've
got a question:
The program called 'Guess my Number' goes like this:
# Guess My Number
#
# The computer picks a random number between 1 and 100
# The player tries to guess it and the computer lets
# the player know if the guess is too high, too low
# or right on the money
#import random
print "\tWelcome to 'Guess My Number'!"
print "\nI'm thinking of a number between 1 and 15."
print "Try to guess it in as few attempts as possible.\n"
import random
# set the initial values
the_number = random.randrange(15) + 1
guess = int(raw_input("Take a guess: "))
tries = 1
# guessing loop
while (guess != the_number):
if (guess > the_number):
print "Lower..."
else:
print "Higher..."
guess = int(raw_input("Take a guess: "))
tries += 1
print "You guessed it! The number was", the_number
print "And it only took you", tries, "tries!\n"
raw_input("\n\nPress the enter key to exit.")
So here's the question - the original code has parentheses around the
lines of code with *(guess !=the_number)* and *(guess* *> the_number)*
. I tried to run the program without the parentheses and it runs just
fine. So what are the parentheses for??
Thanks a lot for your time -
Gary

Some use the parentheses for code clarity as it reads easier when it's
grouped by ().
Your code as written won't run as it should, your while loop needs to
change to include your `guess = int(raw_input("Take a guess: "))` as
without it if your first guess is incorrect it would just loop
infinitely (it's currently 1 level of indentation out, as well as your
`tries += 1`).
Welcome to Python and hope you enjoy your stay. :)
