Overview: **kwargs in Python [**kwargs = Variable-Length Keyword Arguments] A function can define parameters for the keyword arguments it expects. However, some functions need to accept different keyword arguments in different function calls. The Need for Variable-Length Keyword Arguments Consider a function that displays information about a person. One call may include a name and

Overview: *args in Python A function normally defines a fixed number of parameters, so the function call must provide the expected number of arguments. However, some functions need to accept different numbers of positional arguments. To solve this need, Python provides *args. This tutorial explains what *args is, how *args works, how Python stores the

Introduction: Positional-Only and Keyword-Only Parameters in Python A function can normally receive an argument by position or by using the parameter name. This gives the caller flexibility in how the function is called. Sometimes, however, a function should control this flexibility. A parameter may need to accept a value only by position, or it may

Introduction: Combining Function Parameters in Python A function may need to handle various scenarios, and for this purpose, it may need to accept different types of input. Combining function parameters in Python provides a way to handle these different input requirements. These input requirements can vary depending on the scenario. To handle these different requirements,

Introduction: Parameters and Arguments in Python Functions often need values to work with. For example, a function that calculates a total may need a price and quantity, while a function that displays a message may need a name. Parameters and Arguments in Python allow functions to receive these values. So, how does a Python function

Overview: Python Function Parameters, Arguments and Return Values Python functions can accept different types of inputs, from simple values to a variable number of positional or keyword arguments. Understanding how parameters and arguments work, how different parameter types can be combined, how arguments can be unpacked, and how functions return values helps in working with

Introduction: Defining and Calling Functions in Python Defining and calling functions in Python starts with using the def keyword and a function name. When you define a function, you specify the instructions that belong to it. When you call the function, Python executes those instructions. For example, the following code defines a function named greet()
