On the basis of String Develop the code for the following program

1. Python program to check whether the string is Symmetrical or Palindrome
2. Python program to find uncommon words from two Strings
3. Write a Python program to add ‘ing’ at the end of a given string (length should be at least 3). If the given string already ends with ‘ing’ then add ‘ly’ instead. If the string length of the given string is less than 3, leave it unchanged. Example:- Sample String : ‘abc’ Expected Result : ‘abcing’ Sample String : ‘string’ Expected Result : ‘stringly’

Note:- Write and develop code in your IDE , then copy the code and paste in word file then paste the screenshot of the code and screenshot of the output and make the pdf and upload the same .
