How to check that all elements in a list are unique : <p>How can i write a program to check that all elements in a list are unique.
I have a list that is entered by the user and i would like the program to check that the elements are unique, if they are, say list=[1,2,3,4,5], then the program continues. If not, say list=[1,2,3,4,5,5,5], then the user must reenter the list.
Thankyou </p>
