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 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 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]
Read MoreHow to create Python dictionary by enumerate function?
Python enumerate() function takes any iterable as argument and returns enumerate object using which the iterable can be traversed. It contains index and corresponding item in the iterable object like list, tuple, or string.Such enumerate object with index and value is then converted to a dictionary using dictionary comprehension.>>> l1=['aa','bb','cc','dd'] >>> enum=enumerate(l1) >>> enum >>> d=dict((i,j) for i,j in enum) >>> d {0: 'aa', 1: 'bb', 2: 'cc', 3: 'dd'} Learn Python with our step-by-step Python Tutorial.
Read MoreHow to Calculate the Value of nPr in Swift?
nPr is known as n permutation r, where n represents the total numbers and r represents the arrangement of the elements. A permutation is known as the arrangement of elements in a specified order. Elements can arrange either in a sequence or in a linear order, for example, we have a set of elements [2, 4], so the permutation is: [4, 2], [2, 4]. In permutation the order of elements matters whereas in combination the order of the elements does not matters. We can calculate the value of nPr with the help of the following formula: Formula nPr = ...
Read MoreTech number in Swift
If the given number contains an even number of digits and the digits of the number can be divided into two equal parts from the middle. After dividing the digits sum up the divided digits and find the square of the final sum. If the square is equal to the sum itself then the given number is a tech number otherwise not. Example Demonstration Input 3025 Output Yes the given number is a tech number Input 2341 Output No the given number is not a tech number Here, 3025 is a ...
Read MoreSwift Program to Print Floyd’s Triangle
Floyd triangle is right angle triangled which is named after Rober Floyd. It is created with the help of natural numbers starting from 1 in the top left corner and then the consecutive numbers are filled in the specified rows. Example Demonstration Input 4 Output 1 2 3 4 5 6 7 8 9 10 Here, the size of Floyd’s triangle is 4. So it will print Floyd’s triangle until 4 rows. In Swift, we can print Floyd’s triangle using the following methods: Using for−in loop Using while loop Using recursive function Algorithm ...
Read MoreHow to Write Calculator Program using Switch Case in Swift
A Calculator is an electronic device which is used to perform different types of mathematical operations like subtraction, addition, division, multiplication, etc. We can also create a calculator using Switch case and simple arithmetic operations in Swift programming. It will also perform the same mathematical operations as the original calculator. Example Demonstration Enter any two numbers: Number 1: 43 Number 2: 234 SIMPLE CALCULATOR 1. Addition 2. Subtraction 3. Multiplication 4. Division 5. Percentage Choose (1/2/3/4/5): 2 Result = -191.0 Here, we first enter the numbers on which we want to perform the ...
Read MoreHow to Swap Pair of Characters in Swift?
Swapping pair of characters is a process of interchanging the position of two characters in the given string. This operation is commonly used in various programming languages and applications to manipulate data. Example Input “mumbai” Output umbmia Input “Prita” Output rPtia Here, we divide the given string into a pair of characters like “mumbai”: “mu”, “mb”, “ai”. Now we swap the positions of the characters: “um”, “bm”, and “ia” and create the resultant string: “umbmia”. Similarly for input 2. In Swift, we can swap the pair of characters present in the given ...
