Hi All I am trying to find out the duplicates in a list , as for beginning I wanted to compare the adjacent elements in list , for this purpose I wrote a script for checking the adjacent elements in a list, if same , it prints the result that , the adjacent numbers are same , it not it will print adjacent numbers are same My program works , but at the end of the program execution it throws error
Traceback (most recent call last): File "arrayduplinital.py", line 27, in ? if seats[j] <> seats[j+1]: IndexError: list index out of range I tried my best to find the logic , why this error is coming , I was not able to find the reason , I request your guidance for the reason for this error and how to avoid it I am adding the code which I wrote for this program ************************************************************************************** """ find duplicates in a list (1) Sort the array (2) counter i = 0 j = 0 (3) for j <= length if seats[j] <> seats[j+1] ==> print value j and j+1 are not same else ===> print value j , j +1 are same """ seats = [] i = 0 length = int(raw_input("Enter The Lenght of the array : ")) while i < length: num = int(raw_input("Enter the Seats : ")) seats.append(num) i += 1 print seats seats.sort() j = 0 for j in range(length): if seats[j] <> seats[j+1]: print " The Seat", j , "And the seat", j+1 , "value, which are", seats[j]," and", seats[j+1], "are not same" else: print "The Seats ",j ,"And the seats", j+1, "Values,", seats[j], "and", seats[j+1], "are same" ~ ___________________________________________________________ To help you stay safe and secure online, we've developed the all new Yahoo!
