15 Python Tips : How to Write Code Effectively

Image
 Here are some Python tips to keep in mind that will help you write clean, efficient, and bug-free code.     Python Tips for Effective Coding 1. Code Readability and PEP 8  Always aim for clean and readable code by following PEP 8 guidelines.  Use meaningful variable names, avoid excessively long lines (stick to 79 characters), and organize imports properly. 2. Use List Comprehensions List comprehensions are concise and often faster than regular for-loops. Example: squares = [x**2 for x in range(10)] instead of creating an empty list and appending each square value. 3. Take Advantage of Python’s Built-in Libraries  Libraries like itertools, collections, math, and datetime provide powerful functions and data structures that can simplify your code.   For example, collections.Counter can quickly count elements in a list, and itertools.chain can flatten nested lists. 4. Use enumerate Instead of Range     When you need both the index and the value in a loop, enumerate is a more Pyth

15 awesome Java Interview Questions to know

Java interview is one of the tough interviews for developers coming from other technologies. So I have given very basic interview questions they asked. Really awesome to know these questions. 1. What is JVM? Why is Java called the ‘Platform Independent Programming Language’? JVM, or the Java Virtual Machine, is an interpreter that accepts ‘Bytecode’ and executes it. Java has been termed as a ‘Platform Independent Language’ as it primarily works on the notion of ‘compile once, run everywhere’. Here’s a sequential step establishing the Platform independence feature in Java: The Java Compiler outputs Non-Executable Codes called ‘Bytecode’. Bytecode is a highly optimized set of a computer instruction which could be executed by the Java Virtual Machine (JVM). The translation into Bytecode makes a program easier to be executed across a wide range of platforms since all we need is a JVM designed for that particular platform. JVMs for various platforms might vary in configuration, those they w

Java in Digital Applications Real Usage

Recently I found, some of my friends refreshing Java language skills. I asked them why. They told me many digital applications need proficiency in Java skill. Java is the top skill, and popular in customization of all the tools involved in digital applications.  From the above conversation, I can say that at least core Java everyone should be proficient. In addition to that, Java once upon a time popular as web development language. Since Java is being used in all modern applications.  Of course, there are many other popular languages. Those are Python and Scala.   Top List of  Java Applications Robotic process automation - Daily activities in any offices can be automated with Robotic process automation. Java is the language in this scenario to write backend scripts. Artificial Intelligence -Each AI application involves some sort of programming logic. Where it validates user input and sends back output. The backend logic often is written in Java. Full stack development
