A tuple is a finite ordered list of elements. In mathematics, an n-tuple is a sequence (or ordered list) of n elements, where n is a non-negative integer. There is only one 0-tuple, an empty sequence. An n-tuple is defined inductively using the construction of an ordered pair. Tuples are usually written by listing the elements within parentheses "" and separated by commas; for example, denotes a 5-tuple. Sometimes other symbols are used to surround the elements, such as square brackets "[ ]" or angle brackets "< >". Braces "{ }" are never used for tuples, as they are the standard notation for sets. Tuples are often used to describe other mathematical objects, such as vectors. In computer science, tuples are directly implemented as product types in most functional programming languages. More commonly, they are implemented as record types, where the components are labeled instead of being identified by position alone. This approach is also used in relational algebra. Tuples are also used in relation to programming the semantic web with Resource Description Framework or RDF. Tuples are also used in linguistics and philosophy.
In this programming tutorial, we cover Python lists and tuples. Both data structures contain data, but are slightly different. Python lists are mutable, meaning they can be changed and manipulated. Tuples are immutable, meaning they cannot be changed. This is what sets them apart and why you would use a specific one. Lists are usually more popular, since people want to be able to change them, but tuples are also useful when you do not want or need to change the data. It should also be noted that Tuples are faster to process and iterate through, so this gives them a bonus, again, if you are not needing to manipulate them.

The Tuple data type allows you the store a fixed number of values in one place. Tuples are similar to lists and sets, but they are immutable. Typically, the elements of a tuple are related to each other. In this video, we will use IDLE to define tuples and see how they are used in Python, both as the inputs to functions and as a technique for returning multiple values from a function.

In this Python Tutorial we cover the basics of the Python tuple if you need more information visit our website at http://learnpythontutorial.com/basics-of-the-python-tuple-python-tutorial/ If you have any questions leave a comment and we will help you out. Do not forget to subscribe Fundamentals of the Python Tuple In this Python tutorial, we will discuss the basics of the Python tuple which is another data type in the Python programming language. This is a brief introduction to Python tuples and they will be covered in full in a later section. What is a Tuple? A tuple is similar to a list but a tuple cannot be amended after it has been created which makes tuples immutable. Tuples are a sequence like a list so we would use the index to call our values. Tuples I would say are not us...
She was sitting on a stool in a little bar called the Seldom Scene When I walked over and said hi introduced myself
And what's your name I asked she just smiled
She was wearin' a tiny gold chain with the initials SS on the front And I said wait a minute you are Susie Smith she shook her head
Okay you're Sally Simpson...Sarah and before I could finish
She put her hand on mine and said look it's not important
And I said okay I'll just call you Double S and she nodded
And I said what are you drinkin' Double S she said Scotch'n'Soda
And I said Okay Double S one Scotch'n'Soda comin' up
You live around here I asked
No she said just killin' time till the morning
I got an early plane back to California I live near San Simeon
Oh and you'll be flyin' on a 7-0-7 no doubt I said
How did you know? she asked oh I guess I'm just super-smart
You gonna spend the rest of the night in this bar Double S
No she said I have a motel room I'm at the Surfing Sand
Can I give you a lift thanks
I rented a car but I don't drive it too well she answered
It's a stick-ship haha Double S you are something-special I said
And paid the town and we walked out in the cool evening breeze
She said across the seat and snuggled up close to my side
And I began to run my fingers through her hair
It was soft'n'silky. I opened the door to her room
My lips found her lips and I held her close
And whispered you are a super-sexy lady she simply smiled
I could feel her body slowly soften as her sensuous soul
Swiftly swept me into sublime serenity
Her plane left just as the morning
Sun began to softly streak the starry sky
She kissed me a soft solyuna waved a sultry so long from the window
And I never saw Double S again
Right now she's soaring somewhere above the clouds
And I'm walking home on one
And I just realized I never did find out what Double S stood for
