Python program to find cartesian product of two sets.

Cartesian product of two sets, Let’s consider we have setA = {3, 5} and setB = {6, 7} then the Cartesian product of two sets will be {(3, 6), (3, 7), (5, 6), (5, 7)}

Cartesian product of two sets with Python

Steps to solve the program

1. Initiate two sets setA and setB.
2. Initiate a result set where we will add the combined value of setA and setB.
3. Apply a nested loop, the first loop will pick the value of setA and the second loop will value of setB.
4. Combine setA and setB values in the tuple and add them to the result set.
5. Print result set.

				
					# initiate two sets setA and setB
setA = {1, 3}
setB = {2, 6, 7}
result = set()
# use nested loop to interate over setA and setB elements
for val1 in setA:
    for val2 in setB:
        # add combination setA value and setB value to result.
        result.add((val1, val2))
# print output
print(result)

Output : Cartesian product of two sets values.

51. Problem to find the longest word in a set

In this Python set program, we will find the longest word in a set from a set of words with the help of the below-given steps.

What is set?
Sets are used to store multiple items in a single variable.
The set is one of 4 built-in data types in Python used to store collections of data.
It is an unordered collection data type that is iterable, mutable and has no duplicate elements.

Longest word in a set:

Steps to solve the program

1. Take a set of words.
2. Create two variables to store the word having maximum length and longest word in a set.
3. Assign their values equal to 0.
4. Use a for loop to iterate over words from the set.
5. Use an if statement with the len() function to check whether the length of the word is greater than the max_len variable.
6. If yes then assign the length of that word to max_len variable and word to max_word variable.
7. Print both the variables after loop is finished to see the result.

				
					Set = {"I","am","Learning","Python"}
max_len = 0
max_word = 0
print("Original Set: ",Set)
for word in Set:
    if len(word)>max_len:
        max_len =len(word)
        max_word = word
print("Word having maximum length: ",max_word)
print("Length of the word: ",max_len)

Output :

				
					Original Set:  {'Learning', 'am', 'Python', 'I'}
Word having maximum length:  Learning
Length of the word:  8

3. Use an if statement to check whether the book is present in the second set i.e. intersection of sets.
4. If yes then print that book.

				
					Set1 = {"Lord of the Rings","Harry Potter and the Sorcerer's Stone","The Magic Tree","Tower To The Stars"}
Set2 = {"Wizards of Ice","Call of the Forest","Lord of the Rings"}
print("Original Set1: ",Set1)
print("Original Set2: ",Set2)
print("Common books: ")
for book_name in Set1:
    if book_name in Set2:
        print(book_name)

Output :

				
					Original Set1:  {'Lord of the Rings', 'Tower To The Stars', "Harry Potter and the Sorcerer's Stone", 'The Magic Tree'}
Original Set2:  {'Lord of the Rings', 'Call of the Forest', 'Wizards of Ice'}
Common books:
