This is because x is really a label for the item in your list. It does not represent a reference to the position of element as it occurs in the list. For example: >>> a= ['a','e','i'] In the above list, a[0] is 'a', a[1] is 'e' and so on. So, if you want to change the character 'e' above to 'o', you will have to do: >> a[1] = 'o' >>> a ['a','o','i'] Hope that helps. You may find the enumerate() function useful in this case: http://docs.python.org/2/library/functions.html#enumerate Best, Amit. > > print(vowelList) > > #result: ['a', 'e', 'i', 'o', 'u', 'y'] > > -- > Jim Mooney > _______________________________________________ > Tutor maillist - [email protected] > To unsubscribe or change subscription options: > http://mail.python.org/mailman/listinfo/tutor -- http://echorand.me _______________________________________________ Tutor maillist - [email protected] To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
