What does * mean Python function?
An asterisk * is used for unpacking positional arguments during the function call. positional arguments: Positional arguments means values passed through function call should be in the same order mentioned during the function definition.
What does * do in Python functions?
When defining a function, the * operator can be used to capture an unlimited number of positional arguments given to the function. These arguments are captured into a tuple. Python's print and zip functions accept any number of positional arguments.
What does * indicate in Python?
Multiplication of a list : With the help of ‘ * ‘ we can multiply elements of a list, it transforms the code into single line.
What does * set do in Python?
Set is a data type in python used to store several items in a single variable. It is one of the four built-in data types (List, Dictionary, Tuple, and Set) having qualities and usage different from the other three. It is a collection that is written with curly brackets and is both unindexed and unordered.
What does * do to a variable in Python?
The asterisk (*) prefix in the variable object is used to tell python that it's a packing argument, “Dear python, accept all arguments!”. You do this the same way as you pass multiple arguments. So, you actually can pass any number of arguments into the function.
What is * operator used in Python?
Multiplication Operator: In Python, the multiplication operator is *. Furthermore, its use takes place to find the product of 2 values.
What does * do to a list in Python?
Repetition Operator(*) on List Items. Python List also includes the * operator, which allows you to create a new list with the elements repeated the specified number of times.
What does * represent in coding?
In C++ programming, an asterisk is used to declare a pointer.
What is the meaning of * In function argument in Python?
The asterisk (*) allows us to pass any number of values to the defined function. Python Arbitrary Arguments allows a function to accept any number of positional arguments i.e. arguments that are non-keyword arguments, variable-length argument list. Example – Copy Code.
What does a * next to a variable mean in Python?
A single star means that the variable ‘a' will be a tuple of extra parameters that were supplied to the function.
What does * range do in Python?
The range() function returns a sequence of numbers, starting from 0 by default, and increments by 1 (by default), and stops before a specified number.
What does * in front of variable mean in Python?
While defining a function the single asterisk (*) is used to pass a variable number of arguments to a function. It is nothing but creating a function with non key-word arguments.
What is -*- in Python?
The -*- symbols indicate to Emacs that the comment is special; they have no significance to Python but are a convention. Python looks for coding: name or coding=name in the comment.
What does * do in Python function?
In a function call, a single star means ‘unpack this iterable (list or tuple for example) into zero or more positional argument', and a double star means ‘unpack this dictionary into one or more keyword arguments'. See also (each with worked examples) : Tony Flury's answer to What does * and ** means in Python?
Why do we use * in Python?
If we want to accept only Keyword-Only arguments without any positional arguments, Python allows us to use * in function parameters to achieve this.
What does * do before function Python?
Arbitrary Positional Arguments in Python For arbitrary positional argument, an asterisk (*) is placed before a parameter in function definition which can hold non-keyword variable-length arguments. These arguments will be wrapped up in a tuple.
What does * range do in Python?

What does * before a variable mean?
in front of built-in types, “ * ” means “dereference”, and is meant to get a reference from a pointer (thus reducing the indirection), while “&” means “addressof” and is mean to create a pointer from a reference or variable (thus creating indirection).
