![]() In this article, we learnt how we can pack and unpack tuples in a variety of Ways. In case we want to skip only one argument then we can replace “*_” by “_” Conclusion Print(website,"\t",typ," ",topic) Output Tutorialspoint Data Structure: Unpacking a tuple # UnPacking tuple variables into a group of arguments and skipping unwanted arguments Tup = ("Tutorialspoint", "Python","3.x.","Data Structure:","Unpacking a tuple") “ *_” is used to specify the arbitrary number of arguments in the tuple. The following code explains how to deal with an arbitrary number of arguments. The use of (b, c) in the signature requires that the second argument to the function be a sequence of length two (e.g., 42, -13 ). An example is: def fxn(a, (b, c), d): pass. In python tuples can be unpacked using a function in function tuple is passed and in function, values are unpacked into a normal variable. Tuple parameter unpacking is the use of a tuple as a parameter in a function signature so as to have a sequence argument automatically unpacked. Print(website,"\t",*language," ",topic) Output Tutorialspoint Python 3.x. # Packing tuple variables into a group of arguments Live Demo # Packing tuple variables under one variable name All values will be assigned to every variable in the order of their specification and all remaining values will be assigned to *arguments. Python gives the syntax to pass optional arguments (*arguments) for tuple unpacking of arbitrary length. Problem (from Python Cookbook) You have an N-element tuple that you would like to unpack into a collection of N variables. Print(website,"\t",language," ",topic) Output Tutorialspoint Python Unpacking a tupleĭuring the unpacking of tuple, the total number of variables on the left-hand side should be equivalent to the total number of values in given tuple tup. Tuple Assignment, Packing, and Unpacking. In another way, it is called unpacking of a tuple of values into a variable. Python provides another type that is an ordered collection of objects, called a tuple. # Packing tuple varibles into a group of arguments Packing and Unpacking a Tuple: In Python, there is a very powerful tuple assignment feature that assigns the right-hand side of values into the left-hand side. Tup = ("Tutorialspoint", "Python", "Unpacking a tuple") Live Demo # Packing tuple varibles under one varible name Now let’s take a look at its implementation − Example WHereas in packing, we put values into a regular tuple by means of regular assignment. THis act of mapping together is known as unpacking of a tuple of values into a norml variable. Python offers a very powerful tuple assignment tool that maps right hand side arguments into left hand side arguments. In this article, we will learn about packing an unpacking tuple type in Python 3.x. Python offers immutable data types known as tuples. ![]()
