Python has a lot of applications where we need to check for the similarities in two collections to avoid extracting evaluation of the value and make programs more effective. Here, we will see a Python program to check if a tuple is a subset of another tuple.

Before going further with the problem, let's recap some basic topics that will help in understanding the solution.

Python programming language is a high-level and object-oriented programming language. Python is an easy to learn, powerful high-level programming language. It has a simple but effective approach to object-oriented programming.

Tuples in Python is a collection of items similar to list with the difference that it is ordered and immutable.

Example:

tuple = ("python", "includehelp", 43, 54.23)

Check if a tuple is a subset of another tuple

In this article, we are given two tuples. And we need to create a Python program to check if a tuple is a subset of another tuple.

Input:
Tup1 = (4, 1, 6)
Tup2 = (2, 4, 8, 1, 6, 5)

Output:
true

This can be done by checking the presence of elements tup1 in tup2. And python provides multiple methods to check for the sam.

Method 1:

One method to solve the problem is by using the issubset() method which checks if one tuple is a subset of another subset.

# Python program to check if a tuple 
# is a subset of another tuple

# Initializing and printing tuple 
tup1 = (4, 1, 6)
tup2 = (2, 4, 8, 1, 6, 5)
print("The elements of tuple 1 : " + str(tup1))
print("The elements of tuple 2 : " + str(tup2))

# Checking for subsets 
isSubset = set(tup1).issubset(tup2)

if isSubset : 
    print("tup1 is a subset of tup2")
else : 
    print("tup1 is not a subset of tup2")

Output:

The elements of tuple 1 : (4, 1, 6)
The elements of tuple 2 : (2, 4, 8, 1, 6, 5)
tup1 is a subset of tup2

Method 2:

Another method to solve the problem is by using all method to check if all elements of the 1^st tuple are present in the 2^nd tuple.

# Python program to check if a tuple 
# is a subset of another tuple

# Initializing and printing tuple 
tup1 = (4, 1, 6)
tup2 = (2, 4, 8, 1, 6, 5)

print("The elements of tuple 1 : " + str(tup1))
print("The elements of tuple 2 : " + str(tup2))

# Checking for subsets 
isSubset = all(ele in tup2 for ele in tup1)

if isSubset : 
    print("tup1 is a subset of tup2")
else : 
    print("tup1 is not a subset of tup2")

Output:

The elements of tuple 1 : (4, 1, 6)
The elements of tuple 2 : (2, 4, 8, 1, 6, 5)
tup1 is a subset of tup2
