Type error can only concatenate tuple not int to tuple

Python Basics

In Python, you can “add” two strings together by concatenating them. This is done with the + operator:

What is Python?

Python is a programming language with many features, such as Object Oriented Programming, that can be used to create a wide variety of applications. Python is also relatively easy to learn, which has made it one of the most popular programming languages in the world.

What are the benefits of using Python?

Python is a high-level, interpreted, general-purpose programming language, created on December 3, 1989, by Guido van Rossum, with a design philosophy entitled, “There’s only one way to do it, and that’s why it works.”

In the Python language, that means explicit is better than implicit. It also gives rise to the infamousZen of Pythonquote:

There are multiple benefits of using Python which has made it such a popular programming language nowadays. A few reasons why people opt for Python are because:

1) It is easy to learn for beginners and has extensive support libraries
2) It is open source and free to use even for commercial purposes
3) It can run on multiple platforms like Windows, Linux, Mac etc.
4) Python has a large and supportive community
5) Extensive libraries in Python cover areas like machine learning, artificial intelligence, data science etc.

What are the key features of Python?

Python is a widely used high-level interpreted programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace. It provides constructs that enable clear programming on both small and large scales.

Data Types

There are two type of data type in Python tuple and int. The main difference between the two is that a tuple is immutable while an int is mutable. A tuple is a sequence of immutable Python objects.

What is a data type?

In computer science and computer programming, a data type or simply type is an attribute of data which tells the compiler or interpreter how the programmer intends to use that data. Most programming languages support basic data types of integer numbers (of varying sizes), floating-point numbers (which approximate real numbers), characters and Booleans. A data type constrains the values that an expression, such as a variable or a function, might take. This data type defines the operations that can be done on the data, the meaning of the data, and the way values of that type can be stored.

Common data types include:

Integers: whole numbers, such as 42 and -5.
Floating-point numbers: fractional numbers like 3.14159 and -2.718281828. In most programming languages, these are called floats.
Characters: single letters, punctuation marks, whitespace characters, and symbols like ‘a’, ‘9’, ‘+’, ‘$’, ‘\t’ (tab character) and ‘\n’ (newline character). In some languages they are called chars.
Strings: ordered collections of one or more characters, like “hello world” or ” Monty Python “. In some languages they are called atomics , atoms or symbols .
Booleans (or booleans): logical values that can only be true or false .

What are the different data types in Python?

In Python, there are different data types that can be used for different purposes. These data types can be divided into two groups: mutable and immutable.

Mutable data types are those that can be changed, or modified, after they have been created. Immutable data types cannot be changed after they have been created.

The most common mutable data types in Python are lists and dictionaries. The most common immutable data types are strings and integers.

Other data types in Python include tuples, sets, and booleans.

What is the difference between a tuple and a list?

Python has two built-in data structures that can be used to hold a sequence of values: the list and the tuple. They are very similar, but there is an important difference between them. A list is a mutable data structure, which means that you can change the values in a list without changing the list itself. A tuple is an immutable data structure, which means that once you create a tuple, you cannot change the values in it without changing the tuple itself.


The error you’re encountering is because you’re trying to concatenate a tuple and an int, which isn’t possible. Tuples are immutable, meaning you can’t change them once they’re created. You can only concatenate two tuples together. In order to fix this error, you’ll need to convert the int into a tuple.

What is a TypeError?

TypeError is one of several built-in exceptions raised when Python encounters an internal error. Unlike other exceptions, TypeError is not raised by the Python interpreter itself at the time of execution. Rather, it is raised by an object when it receives a request (or message) it can’t respond to. In practical terms, a TypeError occurs when you try to use a value with an inappropriate type.

What causes a TypeError?

TypeErrors occur when you try to use a value with an incompatible type. For example, you can’t use a string value (type “string”) where a numerical value (type “number”) is expected. In the following example, the program tries to convert the string value “10” to a number, but can’t because it’s a string of characters instead of an actual number:

console.log(10 + “10”); // Prints “1010”
console.log(“10” + 10); // Prints “1010”
console.log(10 + 10); // Prints 20

TypeErrors can also occur when you try to perform an operation on a value that does not support that operation. For example, you can’t use the + operator on an Array value:

console.log([1, 2, 3] + [4, 5, 6]); // Prints “1,2,34,5,6”

How can you fix a TypeError?

A TypeError occurs when you try to do an operation or action that is incompatible with the type of object you are working with. In other words, you can only operate or act on certain types of objects (e.g., tuples) in a certain way.

TypeErrors are usually caused by trying to concatenate or combine two objects that are not compatible types. For example, you can only concatenate a tuple to another tuple, not a tuple to an int.

The way to fix a TypeError is to change the way you are trying to combine the objects so that they are compatible types. In the case of concatenating tuples, you could convert one or both of the tuples into lists, and then use the list concatenation operator (+) to join them together.
