Python function with string argument
What is an argument to a function in Python?
In traditional terms, all argument passing in Python is by value. For example, if you pass a variable as an argument, Python passes to the function the object (value) to which the variable currently refers, not "the variable itself.". Thus, a function cannot rebind the caller’s variables.
What are default arguments in Python?
Default Arguments: Python has a different way of representing syntax and default values for function arguments . Default values indicate that the function argument will take that value if no argument value is passed during the function call. The default value is assigned by using the assignment (=) operator of the form keywordname =value.
What are the parameters of a python function?

What is the function of Python?
Python - Functions. A function is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing. As you already know, Python gives you many built-in functions like print(), etc. but you can also create your own functions.

Argument Mechanics n We call this behavior “passing by value” n We are essentially creating two copies of the data that is being passed – one that stays in the main program and one that is passed as an argument into our function n This behavior allows us to set up a “one way” communication mechanism – we can send data into a function as an
