We all know that Excel is a very robust application offered by Microsoft which we use to analyze, organize and visualize our data to extract useful information. So let us assume that we are working in excel sheets. Now while working in excel sheet, there are chances that we leave blank spaces, for eg. leaving blank rows. So from this the built in functions of excel does not work properly. So here you will be going to learn how leaving blank spaces in cells can lead to various problems and so we will learn how to prevent blank or ... Read More
There are several ways to color scatterplot by a variable in Matplotlib of the python library. We have three parameters in scatter function namely cmap, alpha and c using which we can change the color of the plot. Matplotlib is one of the libraries available in python which is used to plot and visualize the given data. This can be used as the extension of the Numpy library to plot the arrays. This library has the module called pyplot which makes the visualization and plotting the data very easy. This pyplot module has many functions and parameters which ... Read More
Introduction Binary trees are fascinating data structures that have numerous applications in computer science and programming. One interesting problem is finding the count from the given tree composed of a parent along with its child nodes. The Binary tree is composed of nodes and the root node is decided and from which the child nodes can be given according the user need. The K value is decided and the way it traverses is chosen by the M value. Count of Root to Leaf Paths The graph is created with various nodes holding the values in form of ... Read More
Let us assume that we are working in an excel sheet. Now there are chances that we need to share our excel sheet with other people. Now the data in our excel sheet is very precious and any carelessness with the data can lead us into trouble. So there should always be some protection associated with our excel so that we can prevent it from being deleted. We don’t want our viewers to make unnecessary changes to our excel sheet which can create a problem to others. Excel provides many built in functionalities which we can use to protect our ...

What exactly is the protocol?When two computers share data among each other or across a network, they must adhere to a pre-defined process of data transfer, which is called 'protocol' Protocol Testing Protocol testing tools examine how data packets are sent across a network. The test procedure involves the use of routers and switches to create portions of the equipment and goods tested. The Value of Protocol Testing It also allows for the development of dependable and high-performance network connectivity. Devices would be unable to interpret the electronic signals they send when conversing via network connections if protocols were not ... Read More
Let us assume that we are working in an excel sheet. Now there are chances that we need to fill color in the excel sheet to highlight the data or we want to differentiate the data. Filling colors in the excel sheet can prove to be very helpful. Now there is one problem that occurs, and that problem is that when we fill the color in excel sheet, the grid lines of which the whole spreadsheet is composed of, disappears. Grid lines are simple horizontal and vertical lines which make up the whole excel spreadsheet. It is the gridlines that ... Read More
There are multiple ways to choose elements from the list with the different probability using the numpy library. In python, NumPy library provides a module named random, which has several functions such as choice(), multinomial() etc., which are used to choose elements from an array with different probabilities. The sum of all probability values defined in the list should be equal to 1. Let’s see each way one by one. Using the random.choice() function The random module provides the function choice(), which is used to calculate a random sample from the given 1-d array with the specified probability distribution. ...

There are multiple ways to check whether the element of a given Numpy array is Non-zero. Here are few common ways that we can apply. Using Boolean indexing Boolean Indexing is a technique in Numpy library, that allows for the selection of specific elements from the array based on the Boolean condition. This creates a Boolean mask containing True or False values, which have the same shape and size as per the Boolean condition. Example Following example how to use Boolean indexing to check whether the element of a given numpy array is non-zero. import numpy as np arr = ... Read More
The Python pandas library provides different functions to check whether the day is a weekday or not namely, weekday(), day_name(), isoweekday() etc., Pandas is an open source python library which is used for data manipulation, data analysis, data visualization, data structures etc. This library is widely used in data science and data analysis which provides data cleaning, exploration and transformation. There are many modules and functions available in pandas to work with the given data. Using the weekday() function In python, the weekday() function can be used to determine whether a given day is a weekday or not. This ... Read More
We have different modules and functions available in python language to check whether specified values are present in the given Numpy array. Numpy is abbreviated as Numerical Python, which is a python library used to perform the mathematical, statistical and scientific calculations. The result of the numpy array is returned in the format of array. The arrays can be created in one dimension, two dimension and so on up to 32 dimensions. The Numpy library provides a number of modules and functions which helps us to perform scientific calculations and mathematical calculations. Let’s see each way one by one to ... Read More
