Parameters are defined by the names that appear in a function definition, whereas arguments are the values actually passed to a function when calling it. Parameters define what types of arguments a function can accept. For example, given the function definition: deffunc(foo, bar=None, **kwargs...
Why Would You Use the Special Parameters in Your Function? There are several reasons why you might need to do this: to compensate for poorly named parameters, to ensure backward compatibility, and to provide internal documentation. One common benefit of forcing positional arguments occurs when your...
Python has a large number of special variables that begin and end with double underscores. They are referred to as dunder to keep it brief (from Double Underscores). In this case, "__name__" is pronounced "dunder name."Let's use the Python shell to determine what the value of __main...

Modules in Python are separate code groupings which packages program code and data for reuse. Since modules are separate files, you need to tell Pthon where to find the file to read it into your application. This is usually done using the import or from statements. ...
Note: All the examples are tested on Python 3.5.2 interactive interpreter, and they should work for all the Python versions unless explicitly specified before the output.UsageA nice way to get the most out of these examples, in my opinion, is to read them in sequential order, and for ...
The parameter name as shown in the tool's syntax in Python. Right. That doesn't mean much. What is it used for? Can I reference a parameter with it in code? So some tool dialog's get burdened with parameters. Are we really supposed to refer to all by index and remembe...

In Python, decorators are a powerful feature that allows you to modify or extend the behavior of functions or classes without changing their source code. Decorators are essentially functions themselves, which take another function (or class) as input and return a new function (or class) with add...
in python, parentheses are used to enclose function arguments, and square brackets are used to access elements of a list or dictionary. curly brackets are not used in python. what is the difference between square brackets and curly brackets? square brackets are used to define arrays or to ...
