Python | Zip Uneven Tuple

In this program, we have two tuples of uneven lengths. And we will see a program that will zip uneven length tuples together.

In python, we can join two structures in a certain way in order to make the operation more effectively on them collaboratively. One way to join the tuples is by performing a zip operation on them. 

Zip operation is pair of one record with another to form a nest tuples with pairs of tuple elements as a single unit. This operation is usually performed on even tuples i.e. one tuple with the same length. 

But, if required the same operation can be changed in such a way that uneven tuples can also be operated on. 

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)

Performing the operation to Zip uneven tuples

For performing zip operation on uneven tuples, we need to use elements of the smaller tuple again to zip all the elements of the larger one.

In python, this task can be performed in multiple ways giving the programmer an option to use a method based on the program’s requirement. So, let's see ways to perform the task.

Method 1:

One method to solve the problem is directly by looping over the smaller tuple and multiple times to match them with the elements of the larger tuple.

# Python program to Zip Uneven Tuples

# Creating and printing both the tuples 
tup1 = (5, 1, 7, 9, 2, 0)
tup2 = (3, 4, 6, 8)
print("The value tuples are : ")
print("tuple 1 : " + str(tup1))
print("tuple 2 : " + str(tup2))

# Performing uneven tuples Zip 
# using loops and enumerate
zipedTup = []
for i, j in enumerate(tup1):
	zipedTup.append((j, tup2[i % len(tup2)]))

# printing zipped tuple
print ("The zipped tuple is : " + str(zipedTup))

Output:

he value tuples are : 
tuple 1 : (5, 1, 7, 9, 2, 0)
tuple 2 : (3, 4, 6, 8)
The zipped tuple is : [(5, 3), (1, 4), (7, 6), (9, 8), (2, 3), (0, 4)]

Method 2:

Another approach to solve the problem is by using the cycle method to cycle through the elements of the smaller tuple elements to pair them with all elements of the larger tuple. The cycle() method is present in the itertools library of the python programming language.

# Python program to Zip Uneven Tuples

# importing cycle method from itertools library 
from itertools import cycle

# Creating and printing both the tuples 
tup1 = (5, 1, 7, 9, 2, 0)
tup2 = (3, 4, 6, 8)
print("The value tuples are : ")
print("tuple 1 : " + str(tup1))
print("tuple 2 : " + str(tup2))

# Performing uneven tuples Zip using loops and enumerate
zipedTup = list(zip(tup1, cycle(tup2)) if len(tup1) > len(tup2) else zip(cycle(tup1), tup2))

# printing zipped tuple
print ("The zipped tuple is : " + str(zipedTup))

Output:

The value tuples are : 
tuple 1 : (5, 1, 7, 9, 2, 0)
tuple 2 : (3, 4, 6, 8)
The zipped tuple is : [(5, 3), (1, 4), (7, 6), (9, 8), (2, 3), (0, 4)]
