XPath is a powerful query language used to navigate and extract information from XML and HTML documents. BeautifulSoup is a Python library that provides easy ways to parse and manipulate HTML and XML documents. Combining the capabilities of XPath with BeautifulSoup can greatly enhance your web scraping and data extraction tasks. In this article, we will understand how to effectively use XPath with BeautifulSoup. Algorithm for Using XPath with BeautifulSoup A general algorithm for using Xpath with beautiful soup is : Load the HTML document into BeautifulSoup using the appropriate parser. Apply XPath expressions using either find(), find_all(), ... Read More
Google Cloud Vision API is a powerful cloud-based tool that allows developers to integrate advanced image analysis capabilities into their applications. A lot of images are available in today’s digital age. Vision API is used for extracting meaningful information from these images, such as recognizing objects, detecting text, understanding sentiment, etc. In this article, we will understand how we can use vision API from google cloud to analyze image data. Algorithm Import the required libraries: Import the necessary libraries for the programming language you are using, such as the google.cloud.vision library for Python. Set up ... Read More
Sometimes we need to sum up the values of nested dictionary values so in this problem statement we are required to find the summation of the nested dictionary values using Python. Understanding the Problem The problem at hand is to find the summation of values present in the nested dictionary and we have to implement the code using Python. So the nested dictionaries are the dictionary inside the dictionary. And we have to find the nested values and sum them up as a result. Sum for all the Nested Dictionary Values In this approach we will add all the values ... Read More
In the given problem statement we are required to find the mirror image of a given string with the help of Python code. Understanding The Problem The problem at hand is to find the mirror image of the given string. The mirror image is the changed version of the given string in which every character is replaced with the mirror image of that character. Or we can say it is the reflection of the string. In real life we see ourselves in the mirror so our right part is visible in the left side in the mirror and similarly the ... Read More
Overview The area of the triangle refers to the full area which means the perimeter of the triangle and the inside area. So to calculate the area of a triangle we will be calculating the perimeter of its and then the area but all these was the manual understanding of finding it. So by using JavaScript we will be automating this whole process which means a user only enters the sides of the triangle and to the interface and the area of the triangle will be calculated automatically. Expression (Heroine's Formula) The given below shows the heroine's formula expression − ... Read More
Variables are fundamental elements in programming that allow us to store and manipulate data. In Python 3, variables are dynamically typed, meaning they can hold different types of data throughout their lifetime. Understanding how to use variables effectively is crucial for writing robust and flexible code. In this article, we will understand the use of variables in Python with the help of different examples. Variable Basics In Python, variables are created by assigning a value to a name using the "=" operator. The name of the variable is chosen by the programmer and should follow certain naming conventions. Variable names ... Read More
In this article we will get to know about various method using which we can find the prefix tuple records using python programming language. Tuple is an immutable sequence-like list whose value cannot be changed once assigned. Here prefix tuple is a collection of tuples which have a common prefix. Each element of tuple can be of any data type or it can also be in mixed form. Example records = [('Kalyan', 123), ('Gungun', 122), ('Komal', 456), ('Isestru', 789), ('Kosal', 321)] prefix = 'Ko' Here you can see we have list of records where tuples are there in ... Read More
In this article we will learn how to find the prefix frequency in a string list using python. There are various ways to solve this program in python, we will look at some of them. Finding prefix frequency can help in finding the pattern and distribution of word uses in the string. Method 1: Using Simple for Loop Example def find_prefix_freq(strings, prefix): count = 0 for string in strings: if string.startswith(prefix): count += 1 ... Read More
In this article we will learn about Power-Function distribution in statistics. We will checkout various methods using which we can analyze the power function distribution. In this post we will also know about how to fit the power function distributions if required. Before that let’s get to know about what Power-Function Distribution is. Power-Function Distribution This is continuous probability distribution used to model the data. Using the power function, we can analyze the small event which create some impact. Using the power function, we can get detail about rare events, identify outliers and can also make predictions about extreme values. ... Read More
In this article we will get to know Power Normal Distribution, its application and uses. We will learn to analyze the distribution by the help of different methods including PDF and CDF. Before that let's see what Power Normal Distribution is. Power Normal Distribution Power Normal Distribution is same as normal distribution only difference is, this distribution includes the power parameter which is used to control the shape of the distribution. It provides us easy way for modeling the data which will show the characteristics of non-normal distribution. Let’s see the power normal distribution using various methods − Method 1: ... Read More
