What are arguments?

Arguments and types of Arguments.

A value passed to a function (or Method) when calling the function. There are two types of arguments:

  • keyword argument: an argument preceded by an identifier (e.g. name=) in a function call or passed as a value in a dictionary preceded by **. For example, 3 and 5 are both keyword arguments in the following calls to complex

· complex(real=3, imag=5)

· complex(**{‘real’: 3, ‘imag’: 5})

  • positional argument: an argument that is not a keyword argument. Positional arguments can appear at the beginning of an argument list and/or be passed as elements of an preceded by *. For example, 3 and 5 are both positional arguments in the following calls:

· complex(3, 5)

· complex(*(3, 5))

Arguments are assigned to the named local variables in a function body See the calls section for the rules governing this assignment. Syntactically, any expression can be used to represent an argument; the evaluated value is assigned to the local variable.

A parameter is a variable in a method definition.

When a method is called, the arguments are the data you pass into the method’s parameters.

Parameter is variable in the declaration of function.

Argument is the actual value of this variable that gets passed to function.
