In Python, the except clause is used to handle exceptions that may occur inside a try block. But what happens if no exceptions are raised? The except block is simply skipped. When No Exceptions Occur If the code inside the try block executes without raising any exceptions, the except block is ignored, and the program continues normally. Example: No exceptions raised In this example, we are performing a simple division that doesn't raise an exception, so the except block does not run - try: result = 10 / 2 print("Division successful:", result) except ZeroDivisionError: ...

In Python, you can create your own custom exception classes to represent specific types of errors in your program. When you raise these custom exceptions, you can also pass an object (like a string or other data) to explain more about what went wrong. This helps make your error messages more useful and detailed. Creating a Custom Exception Class In Python, you can pass an object or any extra information with a custom exception by defining a class that inherits from the built-in Exception class. Inside the custom class, you override the __init__() method to accept additional arguments, and ... Read More
While executing the program, if any statement results in an abnormal value (based on the inputs) where the interpreter doesn't know how to behave. Python throws an exception.In Python, we can also throw or raise an exception manually using the raise keyword. This is helpful when you want to stop the program at a certain point and show that an error has occurred. Using raise to throw a built-in exception You can raise built-in exceptions like ValueError, TypeError, or RuntimeError using the raise statement followed by the exception name and an optional message to explain what went wrong. Example: ... Read More
DFT stands for Discrete Fourier Transform. DFT is a mathematical technique in which we convert the signals of the time domain to their respective signal in the frequency domain, i.e., converting into a list of numbers that tell us which frequencies are present in that signal. Here, by time signal, we mean signals such as audio, temperature, etc that changes over time. The frequency signal means the frequency of each signal present in the time signal. The numbers that tell us which frequencies are present in the signal are called the coefficients. In this article, our task is to compute ... Read More

In C/C++, a variable name can have alphabets, numbers, and the underscore( _ ) character. There are some keywords in the C/C++ language. Apart from them, everything is treated as an identifier. Identifiers are the names of variables, constants, functions, etc. Why Variables in C/C++ Can't Start with Numbers? In C and C++, variable names (also, known as identifiers) cannot start with a digit due to how the compiler processes code during compilation. First, we need to understand the phases of compilation or compiler. There are seven phases in a typical compiler: Lexical Analysis ... Read More
An array is a fixed-size collection of elements of the same data type that stores data in contiguous memory locations. Initializing an array with one default value in C++ is an easy task and can be easily implemented using various approaches that we are going to understand with code examples. Initializing Array with Zeroes in C++ To initialize all elements of an array with 0, we will simply initialize the array with 0 or just use empty curly braces. Example Here is an example that uses the above mentioned methods to initialize the array with 0: #include using ... Read More
While executing the statements that perform arithmetic operations, if any operation results in an illegal value, an arithmetic exception occurs (run time).In Python, ArithmeticError represents this exception, and it is the base class for all errors that occur during arithmetic operations, such as division by zero, overflow, or floating-point errors. Catching this exception helps to manage errors that arise from calculations. Catching ArithmeticError with try-except Block You can use a try-except block in Python to catch ArithmeticError and handle errors related to arithmetic operations like division by zero or overflow. This allows your program to continue running smoothly even if ... Read More
The tag is used to drawn horizontal line on a web page. This tag is one of useful HTML tag. It is used to separate the content by drawing a horizontal line between different sections. In this guide, we are going to learn how we can change the thickness of an tag using CSS using different methods. The tag in HTML The tag stands for horizontal rule. It is a self-closing tag that is used to visually divide the sections of a web page using a horizontal line. Example Section 1 ... Read More
SyntaxError in Python occurs when the interpreter encounters invalid syntax, such as missing colons, unmatched parentheses, incorrect indentation, or invalid keywords. Since this error happens during the code compilation stage (before execution), it cannot be caught using a regular try-except block. To handle it, you must wrap the faulty code inside the exec() or compile() functions within a try-except block. Here, we are demonstarting the occurence of SyntaxError and handling it using the following methods - exec() Method compile() Method Using a custom function with exception handling ... Read More
