Task 2
Given two lists, write python code to print “True” if the two lists have at least one common element. For example, x = [1,2,3], y=[3,4,5], then the program should print “True” since there is a common element 3.
Hint:
We can first calculate set(x) – set(y). set(x) – set(y) is to remove the element in x that also exists in y (3 in this case). So set(x) – set(y) will be equal to (1,2), which is a set. And its length is 2 if you calculate len(set(x) – set(y)).
if set(x) – set(y) has a smaller length than set(x), i.e. len(set(x) – set(y)) This will get easier after we learn the iteration structure and the conditional statement in the next few weeks.
