Explaination

Note : x[:-1] will retrieve all characters except the last and return a new (sub)string.

while loop will run until the given condtion is true i.e string i is in string x, for the 1st iter ; (‘t’, is in x i.e ‘xyztv’ ) thus it proceed inside the loop, once in loop string x is updates to ‘xyzt’, and it prints i , for 2nd iter ; (‘t’, is in x i.e ‘xyzt’ ) thus it proceed inside the loop, once in loop string x is updates to ‘xyz’, and it prints i , for 3rd iter ; (‘t’, is not in x i.e ‘xyz’ ) thus it won’t proceed inside the loop.

Hope this might helps :slight_smile:
