Generally, the age of a person is calculated by subtracting the birth year with the current year then the age of the person will be generated in years. In the same way we can calculate the age of a person by using the python modules datetime, dateutil and timedelta. General Calculation of Age in years Current year - Birth year Example In this example we are implementing the general way of calculating the age using pythn language by passing the current year and birth years as the inputs to created function age_calculator() then the total age will be generated ...

Acceleration, final velocity, initial velocity and time are the terms related to physical science which are widely used to study the motion and mechanics. Let’s see each one in detail. Acceleration Acceleration is the rate at which an object changes its velocity over the given time. It is denoted by a. Mathematically it is defined as the change in velocity divided by the change in time, the following is the formula. The unit of acceleration is meters per second $\mathrm{(m/s^2)}$ $\mathrm{a \:=\:(\Delta;\:vf − \Delta;vi)/\Delta;t}$ Where, $\mathrm{\Delta\:vi}$ is the Initial velocity $\mathrm{\Delta\:vf}$ is the Final velocity $\mathrm{\Delta\:t}$ is the ...

In Python profiling is the measure of performance of different parts of a program to check and identify the areas of optimization and bottlenecks. We have many tools to perform profiling for the python code which includes built in modules, libraries and IDEs (Integrated development environments). There are different types of profiling of the python code, let’s see them one by one. Using Line profiling Line profiling is the technique used to measure the execution time of each individual line of the program. It helps us to identify which line is taking more execution time and to identify the tight ... Read More
Flask is one of the web frameworks which provide libraries to build light weight web applications in python. It is a micro framework, developed by Armin Ronacher who runs an international group of python enthusiasts (POCCO). Flask works on WSGI toolkit and jinja2 template engines. For creating the profile application using python flask and MySQL we have to follow the below mentioned steps one by one. Step − 1 Install the virtual environment by executing the below mentioned command in the command prompt. pip install virtualenv Once the virtual environment is created we can create the new virtual environment into ...

The ProcessPoolExecutor class in python is part of the concurrent.futures module, is a high level interface for asynchronously executing functions using the processes and threads. The ProcessPoolExecutor allows us to execute the multiple functions in parallel using the multiple processes, which is particularly useful to CPU bound tasks that benefit in the parallelization process. Multiprocessing and Multithreading Before going to see about the ProcessPoolExecutor class we have to know about the Multiprocessing and Multithreading. Multiprocessing and Multithreading are the techniques used to achieve the parallelism process and they are different in the way they manage and create concurrent tasks. Multiprocessing ... Read More
In today's data-driven world, the ability to swiftly search and retrieve specific information is vital. This is particularly true when dealing with large datasets spread across multiple sheets or worksheets within a file. Manually skimming through each sheet can be time-consuming and prone to errors. In this article, we will explore creative, efficient techniques that allow us to rapidly locate desired values within various sheets or worksheets without sacrificing accuracy. With Excel's automated search functions integrated into multiple workbook references ensures flawless consistency as formulas perform checks against each dataset independently before returning results accurately. Benefits of Searching a Value ... Read More
As we navigate through the vast world of spreadsheets, there often comes a time when line breaks in our data cells can become inconvenient and seemingly insurmountable obstacles. Whether you're handling large datasets or managing simple reports, removing these unwanted line breaks quickly is essential to maintaining clean and organized information in Excel. A line break refers to the point at which text within a cell automatically moves onto the next line rather than continuing horizontally beyond the visible bounds of that cell. It allows you to add multiple lines within one cell while ensuring readability without affecting column widths ... Read More
Excel is a priceless tool, when it comes to organizing and analyzing data. The IF function is one such function that enables us to carry out calculations based on particular circumstances. While users mostly rely on it for data analysis and calculations, many overlook an underutilized feature that can greatly enhance productivity and decision-making capabilities. In this article, we will explore how to properly utilize the IF function in Excel to quickly rank values while ignoring any errors that may be present. Purpose of Ignoring Errors While Ranking Values Enhancing Data Accuracy Excel mistakes should be ignored in order to avoid ... Read More
One of the most popular software programs in the world is excel which provides a variety of capabilities to make data management and mathematical jobs easier. Excel is a crucial tool for organizing data. Although it comes with a number of built-in functions for sorting and ranking data, at first glance working with non-continuous ranges could seem difficult. Ranking values according to particular criteria is one such priceless feature that enables users to quickly spot trends or conduct in-depth analyses of large data sets. In this article, we will explore how we can quickly rank non-continuous ranges in Excel by ... Read More
Excel is a versatile tool that goes beyond mere calculation and data organization. One of its lesser-known but powerful features lies in the list box control, which allows us to manage and manipulate lists seamlessly. In this article, we will explore a simple yet effective method to swiftly move items between two list boxes in Excel, providing an invaluable skill for efficient data management. Before diving into the process of transferring items between the list boxes, ensure that your Excel worksheet includes both source and destination list boxes. We can typically find these controls under the Developer tab within the ... Read More
