In this video you will learn about variable arity function or varargs in python.

Variable Arity Function or VarArgs
Arity means the number of arguments which are required to call a function. E.g. if a function takes two arguments then its arity is 2. Variable arity means we can pass any number of arguments while calling the function.
If you do not know the actual number of arguments which will be passed when the function is called then add a * before the parameter name in the function. The parameter which is preceded with * is called variable arity parameter and a var args parameter can store any number of arguments. It becomes a tuple in the function definition. A function which have variable arity parameter is called variable argument function or var arg function.
In the following example we are calling a function named show():
show()
show("Tarun")
show("Tarun",1,20,30,20)
show(1,2,3,4,5,6, "Akshay","Ajay")
As you notice in all above calls of show we are passing different number of arguments, so we will define the show as Variable Arity Function.
def show(*args):
print(args)
Note:
1. A function can have at most one Variable arity parameter.
2. We can also have normal parameter along with variable arity parameter.
3. You can call a variable arity function even without passing any argument also.
