The last node of the list includes the null value in the pointer field, representing the end of the linked list. To implement a linked list that is a collection of nodes of the same type, we use self-referential structures, a structure having a reference to itself. It can define as, ...
args and kwargs are used in Python to pass a variable number of arguments to a function. args is used to pass a tuple of positional arguments, while kwargs is used to pass a dictionary of keyword arguments. List the differences between tuples and lists Tuples and lists are both used ...

Hence, list cells are an elegant solution to the problem of growing lists dynamically in a referentially transparent system; and the implementation is so simple that cells work very efficiently indeed. Many extremely clever people have tried (for decades) to come up with a solution that would a...
Would you write code violating this principle, show why it is a bad design and then fix it? Resources Active-Record Active-Record is the design pattern that promotes objects to include functions such as Insert, Update, and Delete, and properties that correspond to the columns in some underlyin...
As you can see in the snapshot above, we created a database named ‘students’ using create command, and deleted a database named class using DROP command. Working with tables A table in a database is a collection of related data organized in a table structure. It’s made up of column...
The Python programming language is extremely powerful and commonly used to automate time-intensive activities/tasks for users. This makes Python a good skill to have for any job that requires automation to replace data in a file, [...] Data Management with Python and SQL MicroBachelors ...

Data-Mapper is a design pattern that promotes the use of a layer of Mappers that moves data between objects and a database while keeping them independent of each other and the mapper itself. On the contrary, in Active-Record objects directly incorporate operations for persisting themselves to ...
In your opinion and experience, which are the limits and pitfalls of the this pattern? Resources Data-Mapper Data-Mapper is a design pattern that promotes the use of a layer of Mappers that moves data between objects and a database while keeping them independent of each other and the ...
