Tuple Concatenation Python

In this Python tutorial, I will discuss tuple concatenation in Python, combining multiple tuples into a single tuple.

Suppose you need to maintain consistency and data integrity. You can use the tuple, as once created, it can’t be altered; the only option is to create a new one from the existing one.

So, in this tutorial, I have explained how you can take different tuples and combine them into a single tuple by creating a new one.

Tuple Concatenation Python

First, I want to define “what a tuple is.” A tuple is a set of items in the order. Consider a tuple like a list but with different properties. Because of its immutability properties, you can add, remove, or change the items of the tuple, unlike a list.

How a tuple is created: To create a tuple, you need to specify the elements within parentheses ‘()’, and each item is separated using a comma. For example, look value a tuple is created with elements 4 and 6.

number=(4, 6)

In the above code, you have created a tuple containing two elements, 4 and 6. Now you know about tuple.

Suppose you have more than one tuple and want to concatenate them all. There are multiple ways to do this in Python, which are discussed below.

Concatenate Two Tuples Python Using Plus Operator (+)

You can concatenate the two tuples using the arithmetic operator ‘+’, called plus. The logic is straightforward, as you add two numbers like 4 + 5. Similarly, you concatenate the tuple like tuple1 + tuple2.

For example, you have extracted data from two sensors, one for measuring temperature and the other for humidity, and stored them in separate tuples, as shown below.

temperature = (23, 25, 22, 24)
humidity = (45, 50, 55, 48)

concatenated_data = temperature + humidity

Look at the output. The two tuples, temperature and humidity, are concatenated using the ‘+’ as ‘temperature + humidity’. Thus, the concatenated tuples are stored in the variable ‘concatenated_data’, which contains the items of both tuples as (23, 25, 22, 24, 45, 50, 55, 48).

Now you have concatenated two tuples, but you are not limited to two tuples; you can concatenate any number of tuples using the ‘+’, like ‘tuple1 + tuple2 + tuple3 + …’.

This is how to concatenate two tuples in Python using the ‘+’.

Python Concatenate Tuples Using the Sum() Function

The sum() function in Python allows you to sum or add multiple items in a single item. So here, you can use the sum() function to add multiple tuples to a single tuple.

The syntax is given below.

sum((tuple1, tuple2, ...),())


  • sum(): It is the function that takes the multiple tuple.
  • (tuple1, tuple2, …): These are the tuples inside another parentheses() which you want to concatenate.
  • (): This is the second argument to the sum() function, which represents the starting point for summing the tuple to ensure that the result type is tuple.

For example, suppose you have created an application that contains the three functions that generate a log-in. Each log is generated by a function represented by tuples of strings.

You are responsible for collecting these logs for analysis and monitoring. The generated logs are shown below.

logs_a1 = ("2024-04-10 10:00:00", "ERROR", "Service unavailable"),
logs_b1 = ("2024-04-10 10:05:00", "WARNING", "Disk space low"),
logs_c1 = ("2024-04-10 10:10:00", "INFO", "Task completed successfully"),

Now, you need to concatenate all these three logs into a single tuple to make the analysis process easier. You can use the sum() function, as shown below.

all_logs = sum((logs_a1, logs_b1, logs_c1), ())

The above code concatenates all the logs and stores them in a variable ‘all_logs’. Let’s loop through these concatenated logs and see.

for logs in all_logs:

Look at the output, all three logs logs_a1, logs_b1 and logs_c1 in the form of tuple is concatenated using the sum() function as ‘sum((logs_a1, logs_b1, logs_c1), ())’.

As a result, it returns the combined tuple logs like ‘(‘2024-04-10 10:00:00’, ‘ERROR’, ‘Service unavailable’) (‘2024-04-10 10:05:00’, ‘WARNING’, ‘Disk space low’) (‘2024-04-10 10:10:00’, ‘INFO’, ‘Task completed successfully’)’.

Similarly, you can concatenate any number of tuples using the sum() function.

This is how to concatenate a tuple in Python using the sum() function.


In this Python tutorial, you learned about tuple concatenation in Python using the ‘+’ and sum() methods. Additionally, you learned about the tuple and the sum() method with syntax and how to use it.
