At hand is the challenge of Python lists - an incredibly flexible data structure capable of holding various kinds of information when dealing with lists within lists (where multiple duplicate entries could exist) duplication is likely. Therefore a Pythonic solution must exist that removes duplicated sublists to ensure each sublist in a main list is unique. In this article, we illustrate how to merge duplicates to a list of lists with detailed examples using different approaches. Merging Duplicates to a List of Lists by Using for Loop Code Explanation and Design Steps − Step 1 − Open Jupyter Notebook ... Read More
Nesting lists in Python refers to multiple lists within one another that can be useful when performing data manipulation tasks; however, occasionally we may wish to change or flatten this nested structure by "flattening a list", in Python terminology meaning changing from multiple hierarchical structures into one single (non-nested) structure where all elements belong under equal scope without hierarchy or hierarchies present. In this article, we will illustrate how to merge nested lists in python using different approaches. Merging Nested Lists in Python Using Recursion Method Code Explanation and Design Steps − Step 1 − Import required module: we ... Read More
The cross product is an operation performed on two vectors in three-dimensional space that results in a third vector that is orthogonal (perpendicular) to the original vectors. In this article, we will see the Golang program to find the cross product of two vectors, here we will explore two different methods. Explanation Let us assume we have two vectors A and B. The cross product of the two vectors can be calculated by the formula: C = A X B. Components of a cross product vector can be calculated by formula: Cx =Ay ⋅Bz −Az ⋅By Cy ... Read More
To represent a given set of items in this problem, the smallest number of subgroups must be present and contain unique members in each subset. In this article, the user will learn how to obtain the minimum number of subsets with distinct elements using a counter in Python. Two examples are depicted in this article. Example one uses a dictionary to manually count the instances of each entry whereas example two uses a counter class to calculate the minimum number of subsets with unique elements. To count the instances of elements in a list, the code makes use of the ... Read More
Lexical order can be used in various applications like sorting algorithms, organizing data in dictionaries or indexes, and string comparisons. In this article, we will explain that how to generate a list of alphabets in lexical order. Lexical order is also known as lexicographic or dictionary order. The words are arranged according to the alphabetical order of their components or letters. In English, there are 26 letters, the lexical order will be followed the traditional ordering of the letters from 'a' to 'z'. Here, we are using various methods to accomplish this task. It will also demonstrate a suitable example. ... Read More
The dot product is a measure of how closely two vectors are aligning in the direction that they are pointing towards. The dot product of two vectors is a fundamental operation in linear algebra that calculates the sum of the products of corresponding elements in two vectors. In this article, we will write a Golang program to find the dot product of two vectors using a loop as well as using the go languages range keyword. Explanation The dot product of two vector is calculated by the formula shown below: DOT PRODUCT = A⋅B =Ax ⋅Bx +Ay ⋅By +Az ... Read More
In this article, the user will understand how to encode-decode messages in python. Users can enter a message and select the desired option whether to encrypt or decode it. The encode or decoded message would be depicted on GUI window after clicking on the respective button. The Tkinter module would be used to develop interactive GUI applications. The code creates a straightforward GUI window with an input entry field, two encoding and decoding buttons, and an output label to show the outcome. Message Encode-Decode Using Python Tkinter Code Explanation and Design Steps − Step 1 − Open Jupyter Notebook ... Read More
Problematic data structures include Python lists and dictionaries, these two structures being ordered collections that allow changes, while an unordered dictionary stores values like maps. Dictionaries provide more efficient use by holding key-value pairs; unlike other data types which hold single values at a time as elements in them. In this article, merging two lists involve compiling all dictionaries from both lists into one large list, their order in this merged list will mirror how they appeared in their respective original lists, initially the order may contain only those from one original list followed by others from both original lists. ...

Programming's basic concept of pattern creation entails producing ordered sequences or patterns. Python as a powerful programming language, provides a great range of tools as well as modules that make it simple to manage patterns. The time() is one kind of module that gets tools for managing time-related tasks. The time() module, while mostly used for time monitoring and measurement, can also be creatively utilized to produce dynamic patterns that alter over time. We will examine two different methods for pattern generation using the Python time() function in this article. We will examine the underlying algorithms of each strategy, offer ... Read More
The Number Theoretic Transformation (NTT) is a key component in many computational applications in the field of number theory. It is essential in areas like encryption, signal processing, error-correcting codes, and more because it makes large-number multiplication and convolution processes efficient. The NTT is a fast method for computing polynomial multiplications modulo a prime integer and is closely connected to the Fast Fourier Transform (FFT). We will examine two different methods for implementing the Number Theoretic Transformation in Python in this article. We will look into the Cooley-Tukey algorithm, one of the most popular methods for putting the Fast Fourier ... Read More
