Interconversion of collections to extract the information in the required form is quite useful in advanced technologies like data science and machine learning which required data to be in a specific structure to process it. Here, we will see a program to convert a tuple to an adjacent pair dictionary in Python.

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)

Converting Tuple to Adjacent pair Dictionary

In this program, we have a tuple consisting of integer values. We need to create a Python program that will convert the tuple to an adjacent pair dictionary.

Input:
(4, 1, 7, 8, 9, 5)

Output:
{4: 1, 7:8, 9:5}

For this, we will treverse the tuple and for each pair, convert it to a key-value pair of a dictionary.

In Python, we have multiple methods to perform this task.

Method 1:

One method to solve the problem is by using the slice method which will slice the tuple to a pair of two elements and convert to a key-value pair dictionary using the dict() method.

# Python program to convert tuple to 
# adjacent pair dictionary

# Initializing and printing tuple
myTuple = (4, 1, 7, 8, 9, 5)
print("The elements of the tuple are " + str(myTuple))

# Converting Tuple to adjacent 
# pair dictionary
adjDict = dict(myTuple[idx : idx + 2] for idx in range(0, len(myTuple), 2))

# Printing result
print("Adjacent pair dictionary created form tuple : " + str(adjDict))

Output:

The elements of the tuple are (4, 1, 7, 8, 9, 5)
Adjacent pair dictionary created form tuple : {4: 1, 7: 8, 9: 5}

Method 2:

Another method to solve the problem is by using the zip() method which will create a dictionary consisting of pairs of key-value.

# Python program to convert tuple to 
# adjacent pair dictionary

# Initializing and printing tuple
myTuple = (4, 1, 7, 8, 9, 5)
print("The elements of the tuple are " + str(myTuple))

# Converting Tuple to Adjacent pair dictionary
adjDict = dict(zip(myTuple[::2], myTuple[1::2]))

# Printing result
print("Adjacent pair dictionary created form tuple : " + str(adjDict))

Output:

The elements of the tuple are (4, 1, 7, 8, 9, 5)
Adjacent pair dictionary created form tuple : {4: 1, 7: 8, 9: 5}
