Question

I couldn’t understand why this is happening actually..

Take a look at this python code :

    word = raw_input("Enter Word")
    length = len(word)

    if word[length-1:] is "e" :
         print word + "d"

If I give input “love”, its output must be “loved”. So, when I wrote this in PyScripter IDE, its neither showing error nor the output. But I tried the same code in python shell, its working!

I’d like to know why this is happening.

Answer 1

The is keyword will only work if the strings have exactly the same identity, which is not guaranteed even if the strings have the same value. You should use == instead of is here to compare the values of the strings.

Or better still, use endswith:

if word.endswith("e"):
     print word + "d"
