What are pure functions?

A pure function is a function that will return the same value given the same arguments. A function is not pure if there is something outside the function that can change its return value, given the same arguments.

Common techniques for using the set() function in Python:

1. Create a set from a list:

my_list = [1, 2, 2, 3, 3, 3]
my_set = set(my_list)

2.Add an item to a set:

my_set = {1, 2, 3}
my_set.add(4)

3.Remove an item from a set by its value:

my_set = {1, 2, 3}
my_set.remove(3)

4.Check if an item is in a set:

my_set = {1, 2, 3}
if 3 in my_set:
    print("The item is in the set.")

5.Get the length of a set:

my_set = {1, 2, 3}
set_length = len(my_set)

6.Loop through the items in a set:

my_set = {1, 2, 3}
for item in my_set:
    print(item)

7.Get the union of two sets:

set1 = {1, 2, 3}
set2 = {3, 4, 5}
union_set = set1.union(set2)

8.Get the intersection of two sets:

set1 = {1, 2, 3}
set2 = {3, 4, 5}
intersection_set = set1.intersection(set2)

Common techniques for using the zip() function in Python:

1. Zip two lists together:

list1 = [1, 2, 3]
list2 = [4, 5, 6]
zipped_lists = zip(list1, list2)

2. Unzip a zipped list:

zipped_lists = [(1, 4), (2, 5), (3, 6)]
list1, list2 = zip(*zipped_lists)

3. Loop through a zipped list:

zipped_lists = [(1, 4), (2, 5), (3, 6)]
for item1, item2 in zipped_lists:
    print(item1, item2)

4.Convert a zipped list to a dictionary:

zipped_lists = [(1, 4), (2, 5), (3, 6)]
my_dict = dict(zipped_lists)

5. Zip three or more lists together:

list1 = [1, 2, 3]
list2 = [4, 5, 6]
list3 = [7, 8, 9]
zipped_lists = zip(list1, list2, list3)

The union of two sets can be found using the union() method.

Here is an example:

set1 = {1, 2, 3}
set2 = {3, 4, 5}
union_set = set1.union(set2)

This will create a new set called union_set that contains all of the items from set1 and set2. In this case, union_set will be equal to {1, 2, 3, 4, 5}.

You can also use the | operator to find the union of two sets. For example:

set1 = {1, 2, 3}
set2 = {3, 4, 5}
union_set = set1 | set2

This will produce the same result as the union() method.

Keep in mind that sets are unordered collections of unique items, so the order of the items in the union set may not be the same as the order of the items in the original sets.
