Python program to check if binary representation of two numbers are anagram.
The binary numbers are the basis of how data is stored, processed and transferred. Every integer is internally represented by using a sequence of bits (combination of 0s and 1s). In this article, we will learn how to check if binary representation of two numbers are anagram. Two numbers are said to be binary anagrams if their binary representations contains the same number of 1s and 0s. For example, the number 12 in binary is 1100 and the number 10 in binary is 1010, both have two 0s and two 1s, making them binary anagrams. Using collections.Counter() Class ...
Read MorePython program to find missing and additional values in two lists?
In this article, we will explore how to find missing and additional values in two lists. This type of comparison is can be encountered in the real-world scenarios such as data validation or system synchronization. The task is to determine which elements are missing in one list and what unexpected elements were received. This can be achieved by using the python built-in data structures like sets that allows for easy comparison. Using set() Function The python set() function is used to used to create a new set. A set is a collection of unique elements (each ...
Read MorePython program to list the difference between two lists.
In Python, Lists are one of the built-in data type used for storing collections of data. Python list is a sequence of comma separated items, enclosed in square brackets[]. They are flexible, easy to manipulate and widely used in various applications. In this article, we will explore to list the difference between two lists. Python provides the several built-in methods for achieving this. Using set.difference() Method The python set.difference() method is used to return the new set containing the elements that are present in the first set but not in any other sets provided as arguments. ...
Read MorePython program to communicate between parent and child process using the pipe.
Inter-process communication (IPC) is essential, When multiple processes need to share the data and work together. In Python, multiprocessing module provides various IPC mechanisms, Out of which one is the pipe. The pipe allows the data to be transferred from one process to another in a two-way (duplex) or one-way mode. It is useful when a parent process creates a child process and want them to exchange messages or data. Python multiprocessing.Pipe() Method The multiprocessing.Pipe() is a method in the Python multiprocessing module that return the pair of connection objects connected by a pipe. This pipe can be ...
Read MoreClass or Static Variables in Python?
In this article we are going to learn about class or static variables on python. The class variables or static variables that are used to share across all the instances of a class. Unlike the instance variables which are specific to each object, Class variables maintain the common value for all the objects of the class. They are defined within the class but outside any instance methods, making them accessible to all the instances. These variables are used when we want to have a single shared state or value among all instance. Example 1 Let's look ...
Read MoreHow to import a single function from a Python module?
In Python, the module is a file containing Python definitions and statements. For keeping the code organized, we often write functions in separate modules and import them into main program. While importing the entire module, sometimes we only need a single function from it. Python provides a direct way to do this using the from module_name import function_name syntax. Importing sqrt() from math module In this approach, we are going to use from math module importing the sqrt to import only the sqrt function. The Python sqrt() function is used to calculate the square root of ...
Read MoreHow can I get a list of locally installed Python modules?
Python is a flexible programming language that consists of thousands of libraries and libraries. As the Python environment grows with the installations, it is important to be able to check which packages are currently installed. Whether you are debugging or documenting the environment, listing locally installed python modules can be useful. In this article, we will explore the different ways to get a list of locally installed python modules using the built-in tools and external commands. Using pip list The pip is the Python package installer and the list is tje subcommand that shows all the installed ...
Read MoreCheck if array can be divided into two sub-arrays such that their absolute difference is Ks in Python
In this article we are going to check whether the given array can be divided into two sub-array in such a way that the absolute difference between the sums of these two sub-array is equal to the given value k. The absolute difference is nothing but the non-negative gap between two numbers, calculated as abs(sum1-sum2). In this task the split must produce two non-empty sub-array i.e. at least one element should be present in each part. Example scenarios Following are the example scenarios: Scenario 1 Input: array = [3, 1, 4, 2, 2], K = 4 ...
Read MoreCheck if array contains contiguous integers with duplicates allowed in Python
Check for Contiguous Integers in an Array A sequence of numbers is said to be contiguous if the numbers can be arranged in such a way that each number follows the previous one without any gaps. For example, [11, 12, 13, 14] is a contiguous sequence because there are no missing numbers between the smallest and largest values. In this article, we need to check if an array contains such contiguous integers, even when the duplicates are present. For instance, [11, 12, 13, 13, 14] should still be considered contiguous because the unique numbers are [11, 12, 13, ...
Read MoreHow to delete consonants from a string in Python?
The consonants are the alphabetic characters that is not a vowel (a, e, i, o, u). In Python, String manipulation is the common task, In this article we will explore how to delete consonants from a string using different approaches, including loops, list comprehensions and regular expression. Using Loop In this approach, we are going to declare the variable assignment with vowels in both upper and lower case and then looping through each character in the string. If the character is vowel or a non-alphabet character we will retrieve them and add to result. Example Let's ...
