How to Fix TypeError: Can Only Concatenate Tuple (Not Int) to Tuple

1. Create a Tuple With a Single Object
2. Fix the TypeError: Can Only Concatenate Tuple (Not "Int") To Tuple in Python

In Python programming language, tuple is a data structure that can be used to store a collection of objects separated by a comma ,. The tuple is immutable, meaning you cannot change its objects.

To create a tuple, you need a name for the tuple and the regular parenthesis ( ) and add an object in it separated by a comma ,.

Syntax of a tuple:

my_tpl = (1, 2, 3, 4, 5, 6)
print(type(my_tpl))  # print the type of my_tpl
print(my_tpl)

Output:

<class 'tuple'>
(1, 2, 3, 4, 5, 6)

Create a Tuple With a Single Object

We have already understood in the above program about tuple creation, but that was a tuple with multiple objects. The creation of a tuple might be a little different from the others.

Code Example:

my_tpl = 1
print(type(my_tpl))
print(my_tpl)

Output:

<class 'int'>
1

This belongs to the int class, not tuple, and the reason is to different int and tuple we use a comma , after the object of a tuple.

Code Example:

my_tpl = (1,)
print(type(my_tpl))
print(my_tpl)

Output:

<class 'tuple'>
(1,)

We have defined a tuple with a single object in it.

Fix the TypeError: Can Only Concatenate Tuple (Not "Int") To Tuple in Python

This common error occurs when you try to concatenate the value or values of any data type other than a tuple. Adding an integer to a tuple can cause this error.

Let’s see why this error occurs and how to fix it.

Code Example:

nums_tpl = (1, 2, 3, 4, 5)  # Tuple
num_int = 6  # Integer

# Concatinating a tuple and an integer
concatinate = nums_tpl + num_int
print(concatinate)

Output:

TypeError: can only concatenate tuple (not "int") to tuple

Concatenating an integer to a tuple is not allowed in Python, which is why the TypeError occurs.

To fix the TypeError: can only concatenate tuple (not "int") to tuple, we can use a tuple instead of an integer because we can concatenate two tuples but not a tuple with any other data type.

Code Example:

nums_tpl = (1, 2, 3, 4, 5)  # Tuple
num_int = (6,)  # Tuple

# Concatinating two tuples
concatinate = nums_tpl + num_int
print(concatinate)

Output:

(1, 2, 3, 4, 5, 6)

As you can see, the TypeError is fixed by concatenating two tuples instead of a tuple and an integer.
