Thanks for the encouragement, here is what I have so far.
word=raw_input("Enter a Word or string:")
print word
print word[::-1]
raw_input("\n\nPress the enter key to exit.")
In the print word [::-1] line it gives me this message (sequence index must be an integer) What does that mean
I have wrote 3 other programs in the class.
A famous quote program where the user inputs their favorite quote, and author and it prints it out.
Two number program the user inputs two numbers and the program adds them together, subtracts, multiply, divide, and hexed.
A fortune cookie program that randomly gives one fortune out of 5 to the user.
