There might be times when we need to take the user input in our Tkinter application. We can get the user Input in a Single Line text input through the Entry widget using get() method. To display the Captured input, we can either print the message on the screen or display the input with the help of the Label widget.Example#Import the required Libraries from tkinter import * from tkinter import ttk #Create an instance of Tkinter frame win= Tk() #Set the geometry of Tkinter frame win.geometry("750x250") def display_text(): global entry string= entry.get() label.configure(text=string) ...

Binary is the simplest kind of number system that uses only two digits of 0 and 1 (i.e. value of base 2). Since digital electronics have only these two states (either 0 or 1), so binary number is most preferred in modern computer engineer, networking and communication specialists, and other professionals.Whereas Decimal number is most familiar number system to the general public. It is base 10 which has only 10 symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.Conversion from Binary to Decimal number systemThere are mainly two methods to convert a binary number into decimal number ...

In this tutorial, we will learn to format the strings in TypeScript. The string is the sequence of characters in any programming language, and the same goes for TypeScript.

Below, we will learn different methods to format the string in TypeScript. Using the + operator to merge two or more strings Generally, the '+' operator performs the addition operation of two or more numbers. When we use the + ... Read More

Suppose we have four numbers a, b, c, and d. We shall have to find maximum among them by making our own function. So we shall create one max() function that takes two numbers as input and finds the maximum, then using them we shall find maximum of all four numbers.So, if the input is like a = 5, b = 8, c = 2, d = 3, then the output will be 8To solve this, we will follow these steps −define a function max(), this will take x and yreturn maximum of x and ytake four numbers a, b, ...

Let us suppose that we have created an Entry widget and we want to get the value of it. In this case, we can use the .get() method. It maps the input object into a variable which can be used further to print or display the entered value.ExampleIn this example, we will create an application that will display the input text thorough a label widget.#Import tkinter library from tkinter import * from tkinter import ttk #Create an instance of tkinter frame or window win= Tk() #Set the geometry of tkinter frame win.geometry("750x250") def get_value(): e_text=entry.get() Label(win, text=e_text, font= ...
