Specify the start index and the end index, separated by a colon, to return a part of the string. -- Get the characters from position 2 to position 5 (not included): name='youtube' name[2:5] 'utu' Slice From the Start: name[:5] #from starting to index 5 (exclude) 'youtu' Slice To the End: name[2:] #from 2nd index to end 'utube' Negative Indexing: 0 1 2 3 4 5 6 #positive indexing y o u t u b e -7 -6 -5 -4 -3 -2 -1 #Negative indexing name[-1] 'e' name[:-1] 'youtub' name[:] 'youtube' name [:0] '' name[-5:-2] 'utu' Concatenate String: name+ ' telusko' 'youtube telusko' Github :- https://github.com/navinreddy20/Python- Java:- https://bit.ly/JavaUdemyTelusko Spring:- https://bit.ly/SpringUdemyTelusko More Learning : Java :- https://bit.ly/3x6rr0N Python :- https://bit.ly/3GRc7JX Django :- https://bit.ly/3MmoJK6 JavaScript :- https://bit.ly/3tiAlHo Node JS :- https://bit.ly/3GT4liq Rest Api :-https://bit.ly/3MjhZwt Servlet :- https://bit.ly/3Q7eA7k Spring Framework :- https://bit.ly/3xi7buh Design Patterns in Java :- https://bit.ly/3MocXiq Docker :- https://bit.ly/3xjWzLA Blockchain Tutorial :- https://bit.ly/3NSbOkc Corda Tutorial:- https://bit.ly/3thbUKa Hyperledger Fabric :- https://bit.ly/38RZCRB NoSQL Tutorial :- https://bit.ly/3aJpRuc Mysql Tutorial :- https://bit.ly/3thpr4L Data Structures using Java :- https://bit.ly/3MuJa7S Git Tutorial :- https://bit.ly/3NXyCPu Donation: PayPal Id : navinreddy20 https://www.telusko.com/
