The word "def", short for definition starts a function.
There are two related concepts, both called "keyword arguments". On the calling side, which is what other commenters have mentioned, you have the ability to specify some function arguments by name. You have to mention them after all of the arguments without names (positional arguments), and there must be default values for any parameters which were not mentioned at all. The other concept is on the function definition side: You can define a function that takes parameters by name -- and you don't even have to specify what those names are. These are pure keyword arguments, and can't be passed positionally. The syntax is def my_function(arg1, arg2, **kwargs) Any keyword arguments you pass into this function will be placed into a dictionary named kwargs. You can examine the keys of this dictionary at run-time, like this: def my_function(**kwargs): print str(kwargs) my_function(a=12, b="abc") {'a': 12, 'b': 'abc'}
The default function is built inside of Python.
This is not Python, nor C. Lua is different...
It's still there... Type the following into a python prompt... x = [7,4,3] x.append(5) print(x) and you get the result... [7,4,3,5] It's definitely working in python 3
A function holds code, which means you can essentially 'store' code within the function, allowing it to be 'reused' or 'called' later on.
To create an anonymous function in Python using the keyword "lambda," you can define the function using the syntax: lambda arguments: expression. This allows you to create a concise and efficient function without needing to give it a name.

In programming, the keyword "headstring" can be used to extract a specific number of characters from the beginning of a string. For example, in a function that takes a string as input and uses "headstring" to extract the first 5 characters, the code might look like this: python def extractheadstring(inputstring): head inputstring:5 return head In this function, the "headstring" keyword is used to extract the first 5 characters from the input string and return them as a new string.
It is the name of a large snake
Python programming allows you to write your own programs. For example, to write a function named double that returns the number that you input, but doubled, we would write the following (where >>>> indicates a tab space) def double(x): >>>>x=x*2 >>>>return x
To write a function in ICT (Information and Communication Technology), you typically start by defining the function with a specific name and parameters that represent the inputs. Next, you include the code that executes the desired operations, followed by a return statement if the function needs to output a value. For example, in programming languages like Python, you would use the def keyword to create the function. Finally, ensure to test the function with various inputs to verify its correctness.

Use the copyfile() function in shutils module.
To generate a numpy cartesian product in Python, you can use the numpy.meshgrid() function. This function takes in multiple arrays and returns a meshgrid of all possible combinations of the input arrays.
