In Python, both functions and object methods are used to organize and reuse code, but they have different purposes. To understand which is more fundamental requires understanding how each one works and their roles in Python programming. A function in Python is a block of reusable code that performs a specific task. A method is a function that is associated with an object, meaning it belongs to a class or an instance. While both functions and methods can be used to perform operations, functions are more fundamental in the Python language. Why Functions Are More Fundamental in Python Functions are considered ...

The return statement in Python is used to return a value or a set of values from a function. When a return statement is encountered in a function, the function execution is stopped, and the value specified in the return statement is returned to the caller. Without it, a function simply executes its code but doesn't provide any result back. The return statement allows a function to output a result which can be used later in the program. Why Use the Return Statement? You should use the return statement in the following cases − To ... Read More

In this article we will discuss about how a variable scope works in Python function. The scope of a name is the area of a program in which you can clearly access a name, such as variables. Hence, a variable scope is the region in which we can access a variable as shown in the following example - def multiplication(): product = 7*9 Here, the “product” variable is created inside the function, therefore it can only be accessed within it. In general, the python scope concept is presented using the rule called as the ... Read More

We can use *args and **kwargs in Python to pass a variable number of arguments to a function. In Python, functions usually have a fixed number of arguments. But sometimes, we may need to pass a variable number of arguments. This is where *args and **kwargs come in. Using *args allows a function to accept any number of positional arguments, while **kwargs allows it to accept any number of keyword arguments - Positional arguments are passed to a function in the same order as the parameters are defined. Keyword arguments are passed ... Read More

Anonymous Function in Python An anonymous function is a function which doesn't have a name. We can return a value from an anonymous function, call it at the time of creation or, assign it to a variable. Instead of using the def keyword, which is used for regular functions, anonymous functions are defined using the lambda keyword. Hence, they are commonly referred to as lambda functions. Syntax Following is the syntax to create anonymous functions using the lambda keyword - lambda [args] : expression Although a lambda function can have only one expression, it can have any number ...

Lambda Function in Python Lamda functions are inline functions, i.e., functions that are written in a single line instead of using multiple lines. These are anonymous functions (functions without a name). We can define a lambda function using the lambda keyword. These are typically used when we need to return a function from another function or accept a function as a parameter. We can also use lambda functions with built-in functions like map(), filter(), and sorted(), where we need to perform a small operation quickly without writing a separate full function. Lamda function is basically a shortcut for writing a ... Read More

Unlike JavaScript, we cannot run Python functions (or scripts) directly in HTML, but we can use tools to make it work. While creating web pages, we use HTML to structure the content and JavaScript to make the page interactive (directly in the browser). We can also write the JavaScript code within an HTML file using the tag. If you are learning Python, you might wonder if you can run Python code the same way inside HTML. The short answer is no. You can't run Python code directly in HTML like JavaScript. Web browsers are designed only to understand HTML, ... Read More

We can write a recursive function in Python to find the factorial of a number. Recursion means that a function calls itself repeatedly to work through different stages of the same task. This technique is useful for tasks that follow a repetitive pattern or have a step-by-step structure like calculating factorials, generating the Fibonacci series, or navigating tree structures (tree traversal). The factorial of a number is the product of all positive integers from 1 to that number. It is represented using the symbol n! and defined as − n! = n × (n - 1) × (n - ... Read More

We can pass a Python function as a function argument by treating it like any other object. In Python, functions are first-class objects. This means you can treat them like any other value, assign them to variables, return them from other functions, and even pass them as arguments to other functions. Passing functions as arguments allows you to create flexible and reusable code. This is useful in cases like sorting, filtering, customizing behavior, and implementing callbacks. In this article, we will explore how you can pass a function to another function in Python and how it helps in building higher-order ... Read More

In Python, functions are treated as first-class objects, which means that all functions in Python are treated like any other object or variable. You can assign a function to a variable, pass it as an argument to another function, return it from a function, or even store it in data structures like lists. One very useful feature in Python is that a function can return another function. This means you can define a function inside another function and return it as a result. This is used in advanced programming concepts like closures, decorators, and higher-order functions. Returning a Simple Function ... Read More
