How to hide axes and gridlines in Matplotlib?
To hide axes (X and Y) and gridlines, we can take the following steps −Create x and y points using numpy.Plot a horizontal line (y=0) for X-Axis, using the plot() method with linestyle, labels.Plot x and y points using the plot() method with linestyle, labels.To hide the grid, use plt.grid(False).To hide the axes, use plt.axis('off')To activate the labels' legend, use the legend() method.To display the figure, use the show() method.Exampleimport numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(-10, 10, 50) y = np.sin(x) plt.axhline(y=0, c="green", linestyle="dashdot", label="y=0") plt.plot(x, y, c="red", lw=5, linestyle="dashdot", label="y=sin(x)") plt.grid(False) plt.axis('off') ...

Read MoreDifference Between & and && in C Programming
The "&" and "&&" operators are both logical AND operators in most programming languages, but they can behave differently in certain circumstances. Both "&" and "&&" are operators used for evaluating conditional statements. The most basic difference between the two is that the "&" operator is a logical as well as a bitwise operator, whereas the "&&" operator is only a logical operator. Read this article to find out more about these two operators and how they are different from each other. Let's start with a basic overview of "&" and "&&" operators. What is "&" Operator? The & operator ...
Read MoreWhat are the applications of DBMS?
The Database Management System (DBMS) is defined as a software system that allows the user to define, create and maintain the database and provide control access to the data.It is a collection of programs used for managing data and simultaneously it supports different types of users to create, manage, retrieve, update and store information.Applications of DBMSIn so many fields, we will use a database management system.Let’s see some of the applications where database management system uses −Railway Reservation System − The railway reservation system database plays a very important role by keeping record of ticket booking, train’s departure time and ...
Read MoreFlags register in 8085 Microprocessor
In 8085 microprocessor, the flags register can have a total of eight flags. Thus a flag can be represented by 1 bit of information. But only five flags are implemented in 8085. And they are:Carry flag (Cy), Auxiliary carry flag (AC), Sign flag (S), Parity flag (P), andZero flag (Z).The respective position of these flag bits in flag register has been show the below figure. The positions marked by “x” are to be considered as don't care bits in the flags register. The user is not required to memorize the positions of these flags in the flags register.Fig. Flags registerNow ...

In this chapter, we are going to see how to set, remove and retrieve cookies in a React application.Cookies are the data stored in the form of key-value pairs that are used to store information about the user on their computer by the websites that the users browse and use it to verify them.To set or remove the cookies, we are going to use a third-party dependency of react-cookie.Installing the modulenpm install react-cookieOr, yarn add react-cookieNpm is the node package manager which manages our React package but yarn is the more secure, faster and lightweight package manager.Setting up cookiesIn this ...
Read MoreHow to convert a Torch Tensor to PIL image?
The ToPILImage() transform converts a torch tensor to PIL image. The torchvision.transforms module provides many important transforms that can be used to perform different types of manipulations on the image data. ToPILImage() accepts torch tensors of shape [C, H, W] where C, H, and W are the number of channels, image height, and width of the corresponding PIL images, respectively.StepsWe could use the following steps to convert a torch tensor to a PIL image −Import the required libraries. In all the following examples, the required Python libraries are torch, Pillow, and torchvision. Make sure you have already installed them.import torch ...
Read MoreHow to perform string comparison in TypeScript?
In this TypeScript tutorial, users will learn to make string comparisons. The string comparison is the basic operation required while working with any programming language. Suppose we are developing a web or Android application and need to compare string data such as user id, user name, password, etc. In such cases, string comparison becomes very useful. Using the strict equality (===) operator The best way to compare the strings in TypeScript is to use the strict equality operator. The strict equality operator first checks the types of the left and right operands, and if it matches, it compares the value ...
Read MoreWhat are the DCL commands in DBMS?
Data control language (DCL) is used to access the stored data. It is mainly used for revoke and to grant the user the required access to a database. In the database, this language does not have the feature of rollback.It is a part of the structured query language (SQL).It helps in controlling access to information stored in a database. It complements the data manipulation language (DML) and the data definition language (DDL).It is the simplest among three commands.It provides the administrators, to remove and set database permissions to desired users as needed.These commands are employed to grant, remove and deny ...
Read MoreHow to Find Factors of Number using Python?
In order to find factors of a number, we have to run a loop over all numbers from 1 to itself and see if it is divisible.Examplenum=int(input("enter a number")) factors=[] for i in range(1,num+1): if num%i==0: factors.append(i) print ("Factors of {} = {}".format(num,factors))If i is able to divide num completely, it is added in the list. Finally the list is displayed as the factors of given numberOutputenter a number75 Factors of 75 = [3, 5, 15, 25, 75]
