How do you compare two lists and return in Python?

difference() to get the difference between two lists. Use set() to convert both lists into sets. Use set. difference(s) where set is the first set and s is the second set to get the difference between both sets.

How do you find the unique values of a list in Python?

Using set() property of Python, we can easily check for the unique values. Insert the values of the list in a set. Set only stores a value once even if it is inserted more then once. After inserting all the values in the set by list_set=set(list1), convert this set to a list to print it.

How do you check if two sets are the same in Python?

We can test if two sets are equal using the normal “==” operator. Notice – since sets are unordered, it doesn’t matter that the set other_nums looks like its elements are in a different order. Set equality comparison just takes into account if the two sets share the exact same elements, regardless of order.

How do you compare two unequal lists in Python?

To compare two lists, we are using the set method.

  1. If the length of the two lists is different, the list can not be identical and return False.
  2. Else, Convert both the lists into sets.
  3. Compare these two sets. If the sets are equal, two given lists are the same. Otherwise, two lists are different.

How do you compare two arrays in Python?
