We will learn about what an exception is before learning how to print Python exceptions. An exception occurs when a program fails to execute in the direction it was intended to be. Python throws exceptions when unexpected errors or events occur. It is common for exceptions to be both valid and invalid. Errors and exceptional conditions can be managed in a program through exceptions in a variety of ways. The exception handling technique can be used when you suspect your code may create an error. This can prevent the software from crashing. Following are some common Exceptions in Python - IOError ... Read More
Python functions are used to implement logic that you may want to reuse in multiple places in your code. These functions accept input parameters called arguments. You can also assign default values to these parameters. If you do not pass any value for a parameter during a function call, the default value will be used automatically. Default values are assigned using the assignment operator (=) in the format param=value. The syntax representation and default values for function parameters are different in Python. If no argument value is given during the function call, the default values mean that the function parameter ... Read More
Variables are defined as the containers used to store some data. They represent a memory location. Any type of data or value can be stored in a variable in Python, including integers, strings, float, Boolean etc. In Python, a variable's data type does not need to be specified when it is defined in a program. However, before any function or application can use variables, they must be defined first. It can be done by simply assigning a value to a name as shown below - x = 5 Here, x is the name of a variable. Also, since x ... Read More
MATLAB has a built-in feature called Python integration that allows you to call Python functions directly from your MATLAB code. You don't need to install any extra tools or software as long as Python is already installed on your system; MATLAB can work with it. With Python integration, you can call Python functions, use Python libraries, and interact with Python objects right inside MATLAB. To do this, simply use the py. prefix before the name of the Python function or module. To make this work smoothly, make sure your Python environment is properly set up. Also, the Python ...

In Python, you may notice that code runs faster when it is placed inside a function rather than running directly in the top-level script (global scope). This is due to how Python manages variable lookups and optimizes execution inside functions. Functions have their own local scope, which is much faster to access compared to the global scope. Also, Python internally applies several optimizations when it detects function boundaries. Reasons for Faster Execution in Functions Here are the main reasons why Python code executes faster inside a function - Local Variable Access: Local variables are stored in a fixed-size array, ...

In Python, an exception is an error that occurs at the time of execution. These will terminate the program abruptly. If you are a programmer looking to raise meaningful exceptions, it is important to know the list of standard exceptions Python provides. What Are Python Exceptions? Exceptions in Python are built-in classes that inherit from the base class BaseException. They help you to manage errors like missing files, wrong data types, division by zero, or custom business logic violations. Where Can You Find the Full List? The complete list of built-in exceptions is available in the official Python documentation. You ... Read More
In Python, indentation is used to define the structure and flow of code. Unlike many other programming languages that use braces to define code blocks, Python relies on indentation. If the indentation is incorrect or inconsistent, Python will throw an IndentationError, specifically an unexpected indent error. In this article, we will understand what the unexpected indent error is, how it occurs, and how to fix it. Understanding Indentation in Python In Python, indentation is used to define the boundaries of code blocks, such as loops, conditionals, functions, and classes. Python uses indentation levels (spaces or tabs) to define code blocks, ... Read More
The error that occurs at runtime after successful compilation of the Java program is called a runtime error or unchecked exception. It disrupts the normal flow of a program’s execution and terminates the program abruptly.These errors are not detected by the compiler but by JVM. The runtime errors in Java are represented by a class called RuntimeException. In this article, we are going to learn what RuntimeException is and its common types. Also, we will discuss how to handle RuntimeException in Java. What is RuntimeException in Java? In Java, the RuntimeException of the java.lang package is a parent class of ... Read More
A Character class is a subclass of the class named Object, and it wraps a value of the primitive type char. An object of type Character contains a single field whose type is char. Unicode Category of a Character In Java, the Unicode category of a character refers to the classification of characters based on their general type or usage, such as letters, digits, punctuation, symbols, etc. The java.lang.Character class provides methods to find the category of a character according to the Unicode standard. Unicode Category of a Character using getType() One of the basic ways to find the Unicode ... Read More
This article explains several strategies to avoid deadlock in Java, including a brief introduction to deadlock, strategies, and respective examples. Deadlock in Java In case of multi-threading, a deadlock is a programming situation where two or more threads are holding resources needed by other threads and are blocked forever, waiting for each other (to release the required resource). A deadlock condition will occur with at least two threads and two or more resources.How To Avoid Deadlock in Java? Following is a list of strategies to avoid the deadlock in Java: ... Read More
