In Python, you can execute functions with multiple arguments directly from the terminal using different approaches depending on how your function is defined and how you want to provide the arguments. Executing Python functions from the terminal allows you to quickly test or run code without writing a full script. When a function requires multiple arguments, you can pass them manually, use input prompts, or use command-line arguments with the help of modules like sys or argparse. Using the Python Interactive Shell If you are working in the Python interactive shell, you can define and call functions directly by entering ... Read More

In Python, functions usually have a fixed number of arguments. However, there are situations where we may want to pass a variable number of arguments. In such cases, Python provides two special constructs: *args and **kwargs. *args allows a function to accept any number of positional arguments. **kwargs allows a function to accept any number of keyword arguments. We will discuss both of these concepts deeply in this article. What is "*args" in Python? In Python, *args allows a function to accept any number of positional arguments. These arguments are collected into a tuple inside the function, allowing ... 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 X (n - 1) X (n - 2) ... Read More

Using the inspect module, you can retrieve the source code of a Python function, method, class, or module. The following example demonstrates how to retrieve a function's source code − Example: Retrieve Function Source Code This code defines a simple function my_function(), that accepts two arguments and returns the sum of those arguments. We then retrieve the source code of the my_function function using the inspect.getsource() function and store it in the source code variable. Finally, the source code is output to the console. The inspect.getsource() function operates by reading the function's source code from the file in which it ... Read More

Function overloading means defining multiple functions with the same name but different arguments. This is a built-in feature in many programming languages like C++ or Java. However, in Python, function overloading is not directly supported, but we can achieve it using some techniques. Python uses a concept called dynamic typing, which allows us to define functions that can take different types and numbers of arguments. We cannot create multiple functions with the same name, but we can still achieve similar functionality using methods like default arguments, variable-length arguments, or special modules like functools.singledispatch. Using Default Arguments One way to overload ... Read More
