A graph that does not contain any cycles or loops is called a non-cycle graph. A tree is a non-cycle graph in which every node is joined to another unique node. A non-cycle graph is also known as an acyclic graph. Difference between cycle graph and non-cycle graph − Cycle Graph Non-Cycle graph The graph forms a closed loop. The graph doesn’t form a closed loop. The graph doesn’t contain a depth loop The graph contains each depth. Example 1 let’s take an example of a cycle graph − A Cycle ... Read More

Working with Python dictionaries, a powerful data type, necessitates an understanding of their size and memory requirements. Assuming you're working with word references in Python, you might have to decide their size to allot adequate memory or perform explicit activities. Fortunately, the size of a dictionary can be determined with the help of Python's built-in len() function. A quick and simple way to gauge the dictionary's contents is to use this function, which returns the total number of key-value pairs in the dictionary. Nonetheless, remember that the size of a word reference can differ contingent upon the quantity of sections ... Read More

Data may be extracted from websites using the useful method known as web scraping and a popular Python package for web scraping is BeautifulSoup which offers a simple method for parsing HTML and XML documents, enabling us to extract certain data from web sites. Finding the siblings of a tag is a frequent task while scraping web pages and it can be defined as a tag's siblings are any additional tags that have the same parent as the primary tag. We will go through using BeautifulSoup to locate tags' siblings in this blog article. Installation and Setup To use ... Read More

Finding the roots of polynomials is an essential operation in mathematics, and NumPy provides an easy and efficient way to accomplish this task. NumPy is a powerful library for scientific computing in Python, and its functions for polynomial manipulation are especially useful. Syntax The NumPy library has a function named roots() that can be used to find the roots of a polynomial. numpy.roots(p) where p is the polynomial coefficients represented as a 1D array or sequence. The function returns an array of the roots of the polynomial. Algorithm With NumPy, finding a polynomial's roots is a rather straightforward process ... Read More

Profit and loss percent is an important financial metric that helps in analyzing the profitability of a business. It is calculated by finding the difference between the total revenue and total cost, and then dividing that value by the total cost. In this technical blog, we will learn how to find the profit and loss percent in a given Excel sheet using Pandas. We will be using the same Excel sheet that we used in our previous blog post on finding profit and loss. Algorithm Import the Pandas library and read the Excel sheet using the read_excel() function. Apply ... Read More

Pandas is a popular data manipulation and analysis library in Python that is widely used by data scientists and analysts. It provides several functions for working with data in Excel sheets. One of the most common tasks in analyzing financial data is finding the profit and loss in a given Excel sheet. Setup To handle excel files in Python using Python, you need to install the openpyxl dependency. To do this, open your terminal and type the command − pip install openpyxl After successful installation you can proceed with experimenting with Excel files and spreadsheets. To download the Excel ... Read More

Programmers frequently need to locate a number that is a multiple of another number. We have a number of methods available to us in Python to complete this task. This article will examine various approaches to locating a number that is a multiple of a given integer. The use of a for loop, list comprehension, and the filter function are a few of the methods we'll go through and these techniques can be used in a variety of situations when locating the position of a multiple is required. Algorithm Define a list of numbers Iterate through the list and ... Read More

Django, a broadly used and effective web framework for Python, has made it less difficult for developers to create dynamic, information-driven web applications. One of the essential components of web packages is the capability to create and manage forms. Django affords a robust shape device that allows developers to fast create, validate, and process forms. In this post, we will explore a lesser-acknowledged feature of Django's form system - the {{ form.as_p }} method which makes it smooth to render forms as paragraphs. Django Forms Before diving into {{ form.as_p }}, let's briefly review how Django forms work. Django ... Read More

The file type HDF5 (Hierarchical Data Format 5) is frequently used for storing and handling huge and intricate data sets. It is the perfect option for scientific and industrial uses because it is made to be versatile, scalable, and effective. Python is one of the many programming languages that can be used to generate, read, and modify HDF5 files. We will look at working with HDF5 files in Python in this tutorial. Installation and Setup We need to install the "h5py" package. We can install it using pip, the package installer for Python. pip install h5py Syntax To create ... Read More
