What is tuple () in Python?

What is tuple () in Python?

Tuple. Tuples are used to store multiple items in a single variable. Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Set, and Dictionary, all with different qualities and usage. A tuple is a collection which is ordered and unchangeable.

How tuple is created in Python?

A tuple is created by placing all the items (elements) inside parentheses () , separated by commas. The parentheses are optional, however, it is a good practice to use them. A tuple can have any number of items and they may be of different types (integer, float, list, string, etc.).

What is tuple explain with example?

A tuple may include zero or more elements. To indicate how many elements it contains, it may be called an n-tuple, where “n” is the number of elements. Often, a tuple is represented as a comma-delimited list of the elements, enclosed in parentheses. For example, “(5, 9, 11, 3, 22, 14)” is a “6-tuple.”

Can function return tuple in Python with example?

Use a tuple, for example, to store information about a person: their name, age, and location. Here’s how you’d write a function that returns a tuple. Notice that we didn’t use parentheses in the return statement. That’s because you can return a tuple by separating each item with a comma, as shown in the above example.

What is the 5 tuple?

The “5-tuple” means the five items (columns) that each rule (row, or tuple) in a firewall policy uses to define whether to block or allow traffic: source and destination IP, source and destination port, and protocol.

What is a tuple vs list?

The key difference between the tuples and lists is that while the tuples are immutable objects the lists are mutable. This means that tuples cannot be changed while the lists can be modified. Tuples are more memory efficient than the lists.

Is tuple mutable or immutable?

immutable

We know that tuple in python is immutable. But the tuple consists of a sequence of names with unchangeable bindings to objects. The tuple consists of a string and a list. Strings are immutable so we can’t change its value.

Why is it called a tuple?

Etymology. The term originated as an abstraction of the sequence: single, couple/double, triple, quadruple, quintuple, sextuple, septuple, octuple., n‑tuple., where the prefixes are taken from the Latin names of the numerals. The unique 0-tuple is called the null tuple or empty tuple.

Is a tuple an array?

Typically, a tuple is an array with fixed size and known datatypes. This is to say; you’d use a tuple for a static, well-defined array.

How do I return tuple values?

A Python function can return any object such as a tuple. To return a tuple, first create the tuple object within the function body, assign it to a variable your_tuple , and return it to the caller of the function using the keyword operation “ return your_tuple “.

Can a function return a tuple?

Functions can return tuples as return values.

Why tuples are faster than list?

Tuple is stored in a single block of memory. Creating a tuple is faster than creating a list. Creating a list is slower because two memory blocks need to be accessed. An element in a tuple cannot be removed or replaced.

Why tuple is faster than list?

Tuples are stored in a single block of memory. Tuples are immutable so, It doesn’t require extra space to store new objects. Lists are allocated in two blocks: the fixed one with all the Python object information and a variable-sized block for the data. It is the reason creating a tuple is faster than List.

Which is fast list or tuple?

Creating a tuple is faster than creating a list. Creating a list is slower because two memory blocks need to be accessed. An element in a tuple cannot be removed or replaced.

Does tuple allow duplicates in Python?

31.2 Python Collection Types
Tuples A Tuple represents a collection of objects that are ordered and immutable (cannot be modified). Tuples allow duplicate members and are indexed.

Is tuple value type?

Tuple types are value types; tuple elements are public fields. That makes tuples mutable value types. The tuples feature requires the System.

What are tuple types?

A tuple is a TypeScript type that works like an array with some special considerations: The number of elements of the array is fixed. The type of the elements is known. The type of the elements of the array need not be the same.

Which is faster list or tuple?

How is tuple used as return type?

NOTE: Use of Tuple is valid from Framework 4.0 and above. Tuple type is a class .
…
However, you do have a couple of options:

1. Return a structure that contains multiple members.
2. Return an instance of a class.
3. Use output parameters (using the out or ref keywords)
4. Use a dictionary or key-value pair as output.

How tuple can return multiple values?

Using Comma-separated values (Tuples):
In this method, we use Python to return multiple values by simply separating them by commas. Python basically uses a tuple to achieve this. A common confusion here is that the syntax of tuple requires a pair of brackets ().

Why tuple is immutable in Python?

Tuples and lists are the same in every way except two: tuples use parentheses instead of square brackets, and the items in tuples cannot be modified (but the items in lists can be modified). We often call lists mutable (meaning they can be changed) and tuples immutable (meaning they cannot be changed).

Why is tuple better than list?

Tuples are more memory efficient than the lists. When it comes to the time efficiency, again tuples have a slight advantage over the lists especially when lookup to a value is considered. If you have data which is not meant to be changed in the first place, you should choose tuple data type over lists.

How do I remove duplicates in tuple?

Method #1 : Using set() + tuple() This is the most straight forward way to remove duplicates. In this, we convert the tuple to a set, removing duplicates and then converting it back again using tuple().

Can you return 2 values in Python?

Python functions can return multiple values. These values can be stored in variables directly. A function is not restricted to return a variable, it can return zero, one, two or more values.

How do I return two tuples in Python?

In Python, you can return multiple values by simply return them separated by commas. In Python, comma-separated values are considered tuples without parentheses, except where required by syntax. For this reason, the function in the above example returns a tuple with each value as an element.
