Flask is an incredible choice in the event that you're a Python engineer needing to fabricate a web application. It is a lightweight web framework that is easy to use and understand. Using PyJokes, a Python package with a large number of jokes, we'll show you how to use Flask to create an amusing and interactive joke app in this article. Installation and Syntax To get started with our Flask news application, we need to first install Flask and the pyjokes library which will fetch jokes for us randomly pip install pyjokes flask Before we dive into the implementation ...

The problem statement asks the user that given an array of multiple nested arrays the user is asked to flatten the array and convert any more than one dimensional array into one dimensional array in javascript but without using recursion as the major condition to apply for. Also it is one of the most asked front end javascript questions in javascript that is mostly asked for , it is given a deep nested sample array of elements all the problem statement is asking to flatten the deepest nested array into one single collection of elements in one dimension only. ...

Python developers may create tiny to medium-sized web apps using the well-liked Flask web framework. It is easy to operate and lightweight. This project showcases the use of the News API, a well-known API for gathering news headlines and stories from many sources, to build a straightforward news application. Installation and Syntax To get started with our Flask news application, we need to first install Flask and the News API library. We can install Flask using pip, which is a package installer for Python. We can then install the News API library using the following command − pip install newsapi-python ... Read More
The problem statement asks the user that given two string arrays as an input by the user , we need to delete the elements present in the first string taking in condition which are not present in the second string in javascript. The same problem statement can also be viewed as given two arrays of strings , the solution of the problem statement should return back the newer version of original first string array such that the first string array should only contain the elements that are present in second string array , remembering to preserve the order of ...

Quantile and decile ranks are commonly used statistical measures to determine the position of an observation in a dataset relative to the rest of the dataset. In this technical blog, we will explore how to find the quantile and decile ranks of a Pandas DataFrame column in Python. Installation and Syntax pip install pandas The syntax for finding the quantile and decile ranks of a Pandas DataFrame column is as follows − # For finding quantile rank df['column_name'].rank(pct=True) # For finding decile rank df['column_name'].rank(pct=True, method='nearest', bins=10) Algorithm Load the data into a Pandas DataFrame. Select the ... Read More
Outliers, or data points that are markedly different from other observations, are frequently encountered in data analysis. To prevent them from skewing the outcomes of statistical analysis, it is essential to recognise and handle these outliers. We will look at finding the outlier points from Matplotlib, a well-known Python data visualization library, in this technical blog post. Installation and Syntax The popular Python module Matplotlib is used to build static, animated, and interactive visualizations. Pip, a Python package installer, may be used to install it. Run the following line in your terminal to install Matplotlib − pip install matplotlib ... Read More
Finding the largest file may be helpful in a number of circumstances, including locating the biggest files on a hard drive to make room for smaller ones or examining the size distribution of files in a directory. The biggest file in a directory may be found using a Python script, which will be covered in this article. Algorithm Import the os module. Define a function called find_largest_file that takes a directory as input. Initialize a variable called largest_file to None and a variable called largest_size to 0. Use os.walk to traverse the directory tree recursively, starting from the root ... Read More
Finding the k smallest values of a NumPy arra Installation and Syntax Pip, Python's package installer, is often used to install NumPy. pip install numpy The following function may be used to identify the k NumPy array elements with the smallest values − np.sort(array)[:k] This returns the first k items of the sorted array after sorting it in ascending order. The array may be be sorted using the alternative syntax shown below, which will retrieve the last k entries and sort the array in descending order − np.sort(array)[::-1][:k] Algorithm The algorithm for finding the k smallest ...

Copy documents, which consume additional room on the hard drive as we assemble information on our PC, are a commonplace event and therefore, finding and removing duplicate files manually can be time-consuming and tiresome; Thankfully, we are able to automate this procedure with Python so in this lesson we will take a look at exactly how to do that with a short script. Setup For this tutorial, we'll use the built-in os and hashlib modules in Python, so no additional packages need to be installed. import os import hashlib Algorithm Compose a function called hashfile() that utilizes the ...

In image processing, finding the difference between two images is a crucial step in various applications. It is essential to understand the difference between the two images, which can help us in detecting changes, identifying objects, and other related applications. In this blog, we will explore how to find the difference between two images using the Python Imaging Library (PIL). Installation and Syntax To use PIL, we need to install it using the pip package manager. We can install PIL by running the following command in the terminal − pip install pillow To find the difference between two images ... Read More
