Answer to Question #307111 in Python for ratul

Question

Given a string, create a new string with all the consecutive duplicates removed.

Hint: You may make a new string to store the result. You can check whether the current character and the next character are the same, then add that character to the new string.

Note: Only consecutive letters are removed not all duplicate occurences of a letter. You may try doing this alternative i.e. removing all duplicate letters from a given string, for your own practice.
