The usual way to get an output from function is a return statement. As we have seen in the part 1 of this article, once the interpreter reaches the return statement, it returns the value and ends t...

Sum of intervals is the Codewars challenge that is about counting overlapping intervals. Let’s examine the problem’s description and see if we can devise a valid solution to it. Figure 1: Screens...

Functions are integral part of most programming languages. Together with classes in OOP-supported languages, they make the code more readable, concise, usable, maintainable thus greatly enhancing t...

Coding, like any other skill, needs constant improvement, time investment, commitment and honing. Regardless of the knowledge level you’re at, if you don’t practice, your performance in the field w...

A recursion is problem-solving method which calls itself in a range of calls until the base one. Only the base call is defined with clear solution; other ones are derived from it. A base call final...

When it comes to memory management, the vital task of any developer is taking care of a memory requirements of given program. This assumes allocating and dislocating the memory occupied by the vari...

In the first part of this text, we have seen that the defining characteristic of the Python is the dynamic typing; the possibility of creating variables without their declaration but rather with im...

In traditional, statically-typed languages there is a data type classification which needs implicit declaration to every variable, function and OOP object. If the variable’s data type is for instan...

The final product of the user’s code in Python is .py file. On its execution, the source file is passed to a Python as an argument, compiled to the intermediary byte-code and then interpreted in th...

As Big-O algorithm’s time complexity is very common theoretical concept, investing some time in understanding it can pay off when implementing solution to some problem, because finding time complex...
