To change the color of a line using radiobuttons, we can take the following steps −Create x, sin and cos data points using numpy.Adjust the figure size and padding between and around the subplots.Create a figure and a set of subplots using the subplots() method.Plot curve with x and y data points using the plot() method.Add an axes to the current figure and make it the current axes, using the axes() method.Add a radio button to the current axes.To change the curve with radionbutton, we can use the change_curve() method that can be passed in on_clicked() method.To display the figure, use the show() method.Exampleimport numpy ...

To detect outliers in one dimensional observation data, we can take the following Steps −Create spread, center, flier_high and flier_low.Using the above data (Step 1), we can calculate data.Use the suplots() method to create a figure and a set of subplots, i.e., fig1 and ax1.Set the title of ax1.Now using the boxplot() method and data, make a box and a whisker plot. Beyond the whiskers, data are considered outliers and are plotted as individual points.To display the figure, use the show() method.Examplefrom matplotlib import pyplot as plt import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True np.random.seed(19680801) spread ...

We can automate Google Signup form with Selenium webdriver in Python. To automate this page, we have to first launch the Google Signup page and identify each element on the form.Let us have a look at the Google Signup form −Examplefrom selenium import webdriver #set chromodriver.exe path driver = webdriver.Chrome(executable_path="C:\chromedriver.exe") #implicit wait driver.implicitly_wait(0.5) #launch URL driver.get("https://accounts.google.com/signup") #identify elements within form f = driver.find_element_by_id("firstName") f.send_keys("Test") l = driver.find_element_by_id("lastName") l.send_keys("One") u = driver.find_element_by_id("username") u.send_keys("test124ewin") p = driver.find_element_by_name("Passwd") p.send_keys("test124@") c = driver.find_element_by_name ("ConfirmPasswd") c.send_keys("test124@") #get value entered s = f.get_attribute("value") t = l.get_attribute("value") v = u.get_attribute("value") w = p.get_attribute("value") print("Values entered in form: ...

We can handle SSL certificate with Selenium webdriver in Chrome browser. A SSL is the standardized protocol used to create a connection between the browser and server.The information exchanged via a SSL certificate is encrypted and it verifies if the information is sent to the correct server. It authenticates a website and provides protection from hacking.An untrusted SSL certificate error is thrown if there are problems in the SSL certificate. We shall receive such an error while we launch a website. In Chrome, we use the ChromeOptions class to work with SSL certificates.We shall create an instance of this class ... Read More
We can perform session handling with the help of Selenium webdriver with a TestNG framework. To trigger different sessions, we shall use the attribute parallel in the TestNG XML file.A TestNG execution configuration is done in the TestNG XML. To create multiple sessions, we shall add the attributes – parallel and thread-count in the XML file.The attribute thread-count controls the number of sessions to be created while executing the tests in a parallel mode. The value of parallel attribute is set to methods.In our example, we would have three methods with three different session ids which are executing in parallel.Exampleimport ... Read More
We can install the Selenium package in Anaconda. The conda has multiple packages so that it can be integrated with Selenium, Selenium-pytest, and so on from the below link − https://anaconda.org/searchA conda is a command line tool in the form of a package which is used for Anaconda.It has some similarities with pip. Selenium is present within the community based conda-forge channel available from the below link − https://anaconda.org/conda-forge/seleniumTo complete installation of this package, we can execute any of the below commands −conda install -c conda-forge seleniumconda install -c conda-forge/label/gcc7 seleniumconda install -c conda-forge/label/cf201901 seleniumconda install -c conda-forge/label/cf202003 seleniumRead More
We can get the following-sibling element for a table type of structure in Selenium webdriver. A following-sibling is used to determine the siblings of the context node.Also, these siblings should be present at the same hierarchy of the current node and share the same parent. Let us take an instance of a table with table tag having multiple children with tag tr.Then let us try to identify the elements in the third row highlighted on the below image from the first row which contains the table headers.Syntax//table[@id='table1']/tbody/tr[1]/following-sibling::tr[2]/tdHere, we are locating the third row in the table, but we have provided ...

We can handle Chrome notification in Selenium webdriver. These are generally known as the web push notifications and can be handled with the help of the ChromeOptions class. The below image shows a notification from the browser Chrome −We have to create an object of this ChromeOptions class and apply the addArguments method on it. The parameter --disable-notifications is passed as a parameter to this method. Finally, this information is sent to the ChromeDriver.SyntaxChromeOptions o = new ChromeOptions(); o.addArguments("--disable-notifications");Exampleimport org.openqa.selenium.By; import org.openqa.selenium.chrome.ChromeDriver; import org.openqa.selenium.chrome.ChromeOptions; import org.openqa.selenium.WebDriver; public class NotificationChrome { public static void main(String[] args) throws IOException { ...

We can read test data from an excel sheet and use it to test Facebook login with Selenium webdriver in Python. We can access excel with Python with the help of the OpenPyXL library.To install this library, we have to run the command - pip install openpyxl. Besides, we have to add the statement import openpyxl in our code. To start with, we have to load the excel workbook with the help of the load_workbook method.The path of the workbook is passed as a parameter to this method. Then we have to determine its active sheet by applying the sheet ... Read More
We can read data from an excel sheet in Selenium webdriver in Python.An excel workbook consists of multiple sheets and each sheet consists of cells and columns.To work with excel in Python(with extension .xlsx, .xlsm, and so on) we have to utilize the OpenPyXL library.
