I'm new to python and I'm trying to write a function where the input is a string, and which return True if the string is a palindrome, otherwise returns False but the interpreter doesn't read the function.

this is the program

and the cmd window shows what happens

You should learn a new language using a book, not stackoverflow

  1. Use True/False instead of true/false. You can consider True and False as somehow 'keywords' in Python.
  2. For Python scripts, you don't use def main():. Instead, try using if __name__ == '__main__': under global scope. Look at this for more info.
  3. You have to print something out rather than just return a boolean variable, by using print build-in function.

Well your code doesn't work because there's no such thing as false or true in Python. They are represented as True with capital T and False with capital F. So change it that way. Also you need to print out ex2(str1):

print ex2(str1)

  • I don't think those are the only problems. I tried making those changes and the program still doesn't do anything. – Kevin Dec 11 '15 at 13:26
