The main problem with intersection of lists is that it can be difficult to determine whether two lists contain the same elements.
def intersection(lst1, lst2):
lst3 = [value for value in lst1 if value in lst2]
return lst3
This is a function that takes two lists as input and returns a third list. The third list, lst3, contains all of the elements that are in both of the input lists.
Lists
In Python, lists are a data structure that allows you to store a collection of items. Lists can be either ordered or unordered, and they can contain any type of object.
To create a list in Python, you use the list() function. To access the first item in a list, you use the index() function. To access the last item in a list, you use the len() function. To add an item to the end of a list, you use the append() function. To remove an item from the end of a list, you use the pop() function.
Sets
In Python, a set is a collection of unique objects. Sets are useful for organizing data, and can be used for things like counting, sorting, and filtering.
To create a set in Python, you use the set() function. To add an object to the set, you use the add() function. To get the size of the set, you use the len() function.
To test whether an object is in the set, you use the in operator. To get the value of an object in the set, you use the get() function.
