The Toplevel window is an option to create a child window in an application. It works similar to the default main tkinter window. We can configure the size of a Toplevel window, customize its properties and attributes as well as add widgets that we want to build the component with.For a particular application, if we have defined a Toplevel window, then we can close it using the destroy() method.ExampleIn the following example, we have created an application that contains a button to open a Toplevel window. The Toplevel window or child window contains a label text and a button to ... Read More
We use various geometry managers to place the widgets on a tkinter window. The geometry manager tells the application where and how to organize the widgets in the window. With geometry manager, you can configure the size and coordinates of the widgets within the application window.The pack() method in tkinter is one of the three geometry managers. The other geometry managers are grid() and place(). The pack() geometry manager is commonly used to provide padding and a way to arrange the widgets in the window.To configure the properties and attributes of a widget explicitly after defining it, you can use ...

The Entry widget is used to accept single-line text strings from users.Text widget − Displays multiple lines of text that can be edited.Label widget − Displays one or more lines of text that cannot be modified by the user.Importing tkinter, csv and creating the main window. Name the output window "Data Entry"(any name for output window) and Create three functions based on the output you need. Here the function of add, save and clear is built in to make the buttons work functionally.After providing the input in the window, click the add button. The add function will display a message ...

To use a floating image in HTML, use the CSS property float. It allows you to float an image left or right. More property values include the following:Sr.No.Property Value & Description1noneNot floated2leftFloats to the left3rightFloats to the right4initialDefault valueExampleYou can try to run the following code to use floating image in HTML. Here’s the usage of float right and float left CSS attribute HTML Floating Image Float Right The below image floats to the right. This is demo text. ... Read More
The sqrtm() function of scipy.linalg package can be used to find the square root of an input matrix.Syntaxscipy.linalg.sqrtm(x)Example 1Let us consider the following example −# Importing the required libraries from scipy from scipy import linalg import numpy as np # Define the input array x = np.array([[14 , 2] , [89 , 33]]) print("Input array:", x) # Calculate the square root r = linalg.sqrtm(x) # Display the square root print("Square Root of x: ", r)OutputIt will generate the following output −Input array: [[14 2] [89 33]] Square Root of x: [[3.43430132 0.22262855] [9.90697038 5.54927253]]Example 2Let us take ...

The scipy.linalg package contains a of different functionalities that are used for Linear Algebra. One of them is the inv() function, which is used to find the inverse of a square matrix.Syntaxscipy.linalg.inv(x)Where x is a square matrix.Example 1Let us consider the following example −# Import the required libraries from scipy import linalg import numpy as np # defines the array a = np.array([[5, 3], [6, 4]]) print("Input matrix :", a) # Finding the inverse of a square matrix x = linalg.inv(a) print(" Inverse of Square Matrix A :", x)OutputThe above program will generate the following output −Input matrix ...

The scipy.special package contains a set of different functionalities that are used for mathematical physics. One of them is the logsumexp() function. This function is used to compute the log of the sum of exponentials of input elements. Let us take a couple of examples and see how to use this function.Syntaxscipy.special.logsumexp(x)where, x is the input value.Example 1Let us consider the following example −# Import logsumexp from scipy.special from scipy.special import logsumexp import numpy as np # Input array a = np.arange(10) print("Input Array:", a) # logsum() function res = logsumexp(a) print("logsumexp of a:", res)OutputIt will produce the ...

To set the small font in HTML, use the style attribute. The style attribute specifies an inline style for an element. The attribute is used with the HTML tag, with the CSS property font-size. HTML5 do not support the tag, so the CSS style is used to add font size.Just keep in mind, the usage of style attribute overrides any style set globally. It will override any style set in the HTML tag or external style sheet.ExampleYou can try the following code to add font smaller than the default font in an HTML page ... Read More
