Hello All,
I am new learner of python, it is really an interesting language.Can u guyz hepl me out.
When i run this script, i will enter any one of the option, then enter 2 nos.
Then i used the function to ask or prompt for "Do u want to continue Y/N"; there u have to press either "y" or "n".
If "y" is pressed the options must be displayed
else if "n" is pressed the progarm must exit.
Tthe error i am getting is:
---------------------------------------------------------------------------------
a=input("Press y to continue or n to exit: ")
File "<string>", line 1, in <module>
NameError: name 'y' is not defined
---------------------------------------------------------------------------------
Can any1 say wht is the problem?
Plz giv me the solution.

Please use code tags when posting code. Please read "How to post a question".
Do not use built-in function input(). Code could inadvertently execute, which could cause havoc. Use raw_input() instead.
Try the following: -
-
def toexit():
-
print ""
-
a=raw_input("Press y to continue or n to exit: ")
-
if a.lower().strip() != 'y':
-
# call your code to exit the script
-
# any key other than 'y' will exit

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
