por Do you know how to use the nested function with len (args) to work with two functions? If the answer is no and you would like to learn, we recommend you continue reading this post. As you can see in the post about how to use a nested function In Python, a function of this type is responsible for combining two functions into one to print both processes in the same function.
So, now we will tell you how you can use the nested function with len (args) to reproduce it in your code projects.
How does len( ) work?
Before knowing how to use a nested function, it is important to remember what the len( ) function consists of. According to the official Python documentation, one of the most used programming languages todaythe len( ) function is used to return the size or object number of an object that was entered. The response of this function is given in a tuple, a list or a string.
Nested function with len (args)
Now that you know how len( ) works, you’re ready to dig into the nested function with len (args). On the one hand, len is the size of what results from a functionwhile, on the other, args works with the argument positions of a function.
To delve deeper into the use of this function, below we present the three steps you have to follow to work with the nested function with the len (args) instruction in Python. These steps are to call the main function which will then be nested, define the nested function «nested def» and execute each of the functions.
Call main function
So, the first step to complete the process of working with a nested function with len (args) is to establish the original function. This is the definition of three_parameters. In this case, you must also have the process to print it and, therefore, your code is as follows:
#the main function that the nested function calls
def three_parameters (one, two = 2, three = 3)
print (f «Parameters are worth one = {one}, two = {two}, three = {three}»)
Nested Function Definition
Once you have established this three_parameters function within your code program, it is time for you to start working with the arg function. As you can see, what the len(args) function does is check the size of the positional arguments of the nested function.
So in the first case, if a positional argument arrives that is equal to 1 (==)the first parameter is the list of [0]that is, one, and as a second parameter we can enter the argument *kwargs.
#nested function definition
nested def (*args, **kwargs)
if len(args) == 1
three_parameters = (args [0]**kwargs)
The second case corresponds to the situation where no positional parameter arrives, that is, len (args) is equal to 0. Thus, a value -1 and the arguments that do have names from **kwargs.
elif if len(args) == 0
three_parameters = (-1, **kwargs)
else:
three_parameters (*args, **kwargs)
Now you have to execute the functions set with different values that are passed as arguments. These will be:
#values that are printed with the function
nested ( )
nested (10)
nested (three = 333)
Function execution results
Below, we present the results of the previous execution of the nested functions that were established at first:
The parameters are worth one = 1 two = 2 three = 3
The parameters are worth one = 10 two = 2 three = 3
The parameters are worth one = 10 two = 12 three = 3
This way, you now know how to use the nested function with the statement len (args) for the development of your code programs and you can reproduce this process in other of your projects.
Continue programming with Python
Now that you know the characteristics of the nested function with len (args) and how to use it in your code projects, you can reproduce the process in other programs of any other nature, but made with the Python programming language.
Even so, although you can already remember this process with the practical example that we share with you, it is possible that you are looking for good training to continue learning until you become a true expert.
