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:
@Python_Codes
1. Create a set from a list:
my_list = [1, 2, 2, 3, 3, 3]2.Add an item to a set:
my_set = set(my_list)
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:
@Python_Codes
1. Zip two lists together:
list1 = [1, 2, 3]2. Unzip a zipped list:
list2 = [4, 5, 6]
zipped_lists = zip(list1, list2)
zipped_lists = [(1, 4), (2, 5), (3, 6)]3. Loop through a zipped list:
list1, list2 = zip(*zipped_lists)
zipped_lists = [(1, 4), (2, 5), (3, 6)]4.Convert a zipped list to a dictionary:
for item1, item2 in zipped_lists:
print(item1, item2)
zipped_lists = [(1, 4), (2, 5), (3, 6)]5. Zip three or more lists together:
my_dict = dict(zipped_lists)
list1 = [1, 2, 3]Share and Support
list2 = [4, 5, 6]
list3 = [7, 8, 9]
zipped_lists = zip(list1, list2, list3)
