View Full Version : [SOLVED] Help with a Python 2.7 syntax error

June 14th, 2011, 06:58 AM
Hi guys I am trying to make a game with Python programming language for a school homework piece. To impress teacher I am trying to display knowledge that I have researched on Internet and am having trouble with one area of the program.

print " Welcome"
name = raw_input ("Please enter your name.")
print "Hello " + name
print "Do you want to play a game " + name
answer = raw_input (" Please enter either Yes or No including capital."

if answer == Yes:
print " Ok lets play Too High Too Low."
goto a
print "Okay goodbye"

print "Welcome to the game Too High Too Low."
raw_input ()

I want to have the program ask the user if they want to play the game and whether they answer Yes or No affects the programs running. If the user says yes i want to it to skip to a later area of the program marking by the lower case a coloured red. If the user says no I want the program to close coloured blue. I cannot check if these portions of the program work as Python does not let me run the program because of a basic syntax error coloured green.
If you guys could help with any of these's three problems i would be very grateful.

You can rearrange the logic to avoid using the goto command, and Yes needs to be in quotes, this is how I'd do it:

if answer == "No":
print "Okay goodbye"

<rest of program here, when user types yes>
print " Ok lets play Too High Too Low."

1) I see a few errors in there. As for the one you're asking about, sys doesn't have a quit attribute, you're looking for sys.exit(). I don't see sys imported ... did you?

2) When asking about an error, please provide the error python gives you.

3) Please put code in CODE tags (click the # button) to retain indentation

4) Does python even have a goto command? If it does, avoid it at all costs. Read up on Object Oriented Programming.

Firstly, the number of close brackets must equal the number of open brackets. You're missing a close bracket.

The raw_input function returns a string, not a boolean - in other words, the 'answer' variable will contain the string "Yes", "yes", "y" or something like that, but it will not contain Yes (boolean). You should make sure you tell the user to type y or n, and then put:

if answer == "y":

I don't think Python supports goto. For a simple program I'd put in a function call that contains the game's logic.

Also, sys.exit() is the function you are looking for, and you need to import sys before you can use it.

Now, no more homework help.
