+Suppose you want your program to run error free, well everyone wants that.
+But what if we need our program to run even if there is an error, is there any possibility? Yes There sure is.
+Python provides Try and except, using this you can show user the message when certain error is occurred we call it exception.
+User get the feedback where he went wrong, using Try And Except Technique.
+Giving feedback for your program is every important.
+I hope even I do get some feedback about this 30DaysOfPython, I will be waiting for your feedback.
+Back to Try and Except again, here you will require the knowledge of some common errors
