Introduction If you want your Excel documents to seem more professional and be simpler to read, consider printing borders around each page. This will accomplish both of those goals. The borders separate the information from the white space that is all around it, giving the entire item the appearance of having been polished. This post will begin with a brief introduction, then proceed to provide an explanation, and then conclude by providing a summary of how to print borders around each page in Excel. Why does it Happen? Borders surrounding each page are printed when the page configuration and print ... Read More
Histogram equalization is a technique used in image processing to enhance the contrast of an image by redistributing the pixel intensities in a way that maximizes the overall brightness and detail. The method works by adjusting the frequency distribution of the pixel values in an image, such that the resulting image has a uniform histogram. The uniform histogram ensures that each pixel in the image has an equal chance of appearing, resulting in a well−distributed image with enhanced contrast. Histogram equalization is an important tool in image processing and is commonly used in various applications, including medical imaging, remote sensing, ... Read More
In this article we will learn different approaches with which we can change the value of data present in an excel sheet using python. Openxypl Openpyxl is a Python library used for working with Excel spreadsheets. It is a popular choice for working with Excel files in Python because it is easy to use, has an active developer community, and provides many features for working with spreadsheets. Openpyxl allows you to create, read, write, and modify Excel files using Python. It supports the following file formats: XLSX (Microsoft Excel Open XML Spreadsheet) XLSM (Microsoft Excel Open XML Macro−Enabled ... Read More
FPGA (Field-Programmable Gate Array) and microcontrollers are two types of integrated circuits that serve different functions in electronic systems. While both can be used to implement digital logic functions, they have major architectural, flexibility, and application domain differences. Read this article to find out more about FPGA and Microcontrollers and how they are different from each other. What is FPGA? FPGA is an abbreviation for Field-Programmable Gate Array. It is an integrated circuit (IC) that contains a set of programmable logic blocks and interconnects. FPGAs are distinct in that they may be programmed or configured after manufacturing by a ...

The size of a plot refers to its width and height in units such as inches or centimeters. By adjusting the plot size, we can control how much space it occupies on the screen or in printed media. Seaborn provides several options for modifying the plot size to suit our needs. Seaborn does not have a specific parameter called "figure size" in its API. When using Seaborn to create plots, we can specify the figure size by directly manipulating the Figure object using Matplotlib's functions or parameters. Importing Required Libraries Before proceeding with the approaches, we have to make ... Read More
The axes spines, also known as the axis lines, which are the lines that define the borders or boundaries of a plot's coordinate system. In a two-dimensional plot, there are typically four axes spines such as top, bottom, left, and right. These spines create the framework for the plot and serve as reference lines for the data points. Each spine represents one of the four sides of the plot. The top spine runs horizontally across the top, the bottom spine runs horizontally across the bottom, the left spine runs vertically along the left side, and the right spine runs vertically ...

The CMY and CMYK color models are subtractive color models used in printing and graphic design. In Python, we can work with these color models using various libraries and tools. Let's see each color model in detail. CMY color model The CMY color model, also known as the subtractive color model, which is a system used for mixing colors in various applications like printing, painting, and graphic design. CMY stands for Cyan, Magenta, and Yellow, which are the primary colors in this model. In the CMY color model, colors are created by subtracting different amounts of cyan, magenta, and yellow ...

A regular expression is also referred as regex, which is a sequence of characters that forms a search pattern. It's one of the powerful tools used for pattern matching and manipulating strings. In python we are having a module called re which helps to form a regular expression. Regex patterns consist of ordinary characters such as letters, digits and special characters called metacharacters. Meta Characters have special meanings and allow us to define complex search patterns. The below are some commonly used meta characters in python regular expressions. . (dot) − Matches any single character except a newline. ^ ... Read More
In Seaborn, the "ticks" figure style is a minimalistic style that removes the background grid lines but retains the tick marks on the axes. This style focuses on presenting the data without any distracting elements and is useful when we want a clean and simple look for our plots. When we set the figure style to "ticks" in Seaborn using the 'sns.set_style()' function, the following changes occur in our plots. Background Grid Lines − The background grid lines are removed, resulting in a blank canvas without any horizontal or vertical lines. This helps to reduce visual clutter and draw ... Read More
In Seaborn, the figure style refers to the overall visual appearance and aesthetics of a plot. Seaborn provides several built-in figure styles that can be used to enhance the look and feel of your visualizations. These figure styles affect various elements such as colors, grid lines, background, fonts, and more. To set the figure style in Seaborn, we can use the sns.set_style() function. In this article we are going to see how to change the figure style to Dark in Seaborn. The following are the steps to be followed. Installing Seaborn Library First we have to ensure that Seaborn is ... Read More
