Can Python functions run in html as javascript does?
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 MoreHow to retrieve source code from Python objects?
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 MoreHow to write recursive Python Function to find factorial?
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 MoreHow to list all functions in a Python module?
In this article we will discuss how to list all the functions in a Python module. A Python module contains multiple different functions that allow for extensive code reusability making complex code simple. It also enhances portability of python program by changing platform dependent code into platform independent APIs Python standard library consists of modules written in C that provide access to system functionality and modules written in python that provide general solutions for everyday problems making the life of programmers easy as it prevents writing of long code for simple problems Using dir() to get functions in a module ...
Read MorePython program to find all duplicate characters in a string
This article teaches you how to write a python program to find all duplicate characters in a string. Characters that repeat themselves within a string are referred to as duplicate characters. When we refer to printing duplicate characters in a string, we mean that we shall print every character, including spaces, that appears more than once in the string in question. Input-Output Scenarios Following is the input-output scenario to find all the duplicate characters in a string − Input: TutorialsPoint Output: t, o, i As we can see, the duplicate characters in the given string "TutorialsPoint" are "t" with ...
Read MoreWhat does the if __name__ ==
This article explains what the Python code expression if __name__ == '__main__' means. A Python programme uses the condition if __name__ == '__main__' to only run the code inside the if statement when the program is run directly by the Python interpreter. The code inside the if statement is not executed when the file's code is imported as a module. What is __main__? The word "__name__" denotes a unique variable in Python. Python has a large number of special variables that begin and end with double underscores. They are referred to as dunder to keep it brief (from Double Underscores). ...
Read More__file__ (A Special Variable) in Python
Understanding the __file__ Special Variable The __file__ variable in Python is a special attribute that stores the path to the current script or module from which it is accessed. It is automatically set by the Python interpreter when a script is executed or a module is imported. This variable allows you to determine the exact location of the current file, irrespective of where the Python interpreter is run. The value of the __file__ can be either a relative path or an absolute path, depending on how the script is executed. The __file__ variable contains the relative path to the script ...
Read More__call__ in Python
Python __call__ Method In Python, everything is treated as an object, including integers, strings, classes, and even functions. It provides a special method named __call__ that allows an instance of a class (i.e. object) to behave like a function (i.e. we can call/invoke it). When we define the __call__ method inside a class, we can call its instance (object) using parentheses, just like a regular function. Syntax Following is the syntax to use the __call__ method inside a class − class MyClass: def __call__(self, *args, **kwargs): # Implementation of the method ...
Read MorePython program to check for URL in a string
This article will teach you how to determine whether a string contains a URL or not. In Python, strings are collections of bytes that represent Unicode characters. You can use single or double quotes and everything enclosed in them is considered as a string. When given a string, we will first determine whether it contains a URL. If one is found, we will then print the URL. Using findall() method We will employ Python's regular expression concept to resolve this issue. Regular expressions are supported by the Python re package. Using a particular syntax defined in a pattern, a regular ...
Read MoreSegregate 0’s and 1’s in an array list using Python?
The elements in the contiguous memory address are contained in the linear data structure known as an array. At these places, it primarily groups components of the same data type. Given an array of integers. The array is to be divided into two halves, 0s and 1s, according to the article "Segregate 0s and 1s in an array." The array should have all the 0’s on the left and all the 1’s on the right. Input-Output Scenario Let’s consider an input and its output scenarios to segregate 0’s and 1’s in an array list - Input: [0, 1, ...
