What is tuple give example?
A tuple (pronounced TUH-pul) is a data structure in some programming languages that is an ordered list 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.”.
How do you define a tuple?
A tuple is a collection of objects which ordered and immutable. Tuples are sequences, just like lists. The differences between tuples and lists are, the tuples cannot be changed unlike lists and tuples use parentheses, whereas lists use square brackets.
What is difference between list and tuple?
We can conclude that although both lists and tuples are data structures in Python, there are remarkable differences between the two, with the main difference being that lists are mutable while tuples are immutable. A list has a variable size while a tuple has a fixed size.
What is the use of a tuple?
Tuples are used to group together related data, such as a person’s name, their age, and their gender. An assignment to all of the elements in a tuple using a single assignment statement. Tuple assignment occurs simultaneously rather than in sequence, making it useful for swapping values.
Is a list a tuple?
List and Tuple in Python are the class of data structure. The list is dynamic, whereas tuple has static characteristics. … Tuple is also a sequence data type that can contain elements of different data types, but these are immutable in nature. In other words, a tuple is a collection of Python objects separated by commas.
Which is better list or tuple?
Tuples are faster than lists. Some tuples can be used as dictionary keys (specifically, tuples that contain immutable values like strings, numbers, and other tuples). Lists can never be used as dictionary keys, because lists are not immutable.
How do I turn a list into a tuple?
Typecasting to tuple can be done by simply using tuple(list_name). Approach #2 : A small variation to the above approach is to use a loop inside tuple() . This essentially unpacks the list l inside a tuple literal which is created due to the presence of the single comma (, ).
What is tuple in Python with example?
A tuple in Python is similar to a list. The difference between the two is that we cannot change the elements of a tuple once it is assigned whereas we can change the elements of a list.
What is tuple in SQL?
A table has rows and columns, where rows represents records and columns represent the attributes. Tuple − A single row of a table, which contains a single record for that relation is called a tuple. Relation instance − A finite set of tuples in the relational database system represents relation instance.
Is Python a tuple?
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. Tuples are written with round brackets.
How do you cut a tuple?
To index or slice a tuple you need to use the  operator on the tuple. When indexing a tuple, if you provide a positive integer, it fetches that index from the tuple counting from the left. In case of a negative index, it fetches that index from the tuple counting from the right.
Which is faster list or tuple?
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.
