*args and **kwargs are special keyword which allows function to take variable length argument. *args passes variable number of non-keyworded arguments list and on which operation of the list can be performed.
1.) *args
The special syntax *args in function definitions in python is used to pass a variable number of arguments to a function. It is used to pass a non-key worded, variable-length argument list.
2.)**kwargs
The special syntax **kwargs in function definitions in python is used to pass a keyworded, variable-length argument list. We use the name kwargs with the double star. The reason is because the double star allows us to pass through keyword arguments (and any number of them).
