The list in python is a collection of similar items. We may at times need to compare data items in the two lists to perform certain operations. We will discuss certain methods to compare two lists in python.Using list.sort() and == operatorThe list.sort() method sorts the two lists and the == operator compares the two lists item by item which means they have equal data items at equal positions. This checks if the list contains equal data item values but it does not take into account the order of elements in the list. This means that the list [1, 2, ... Read More

Python is a widely used high-level programming language. To write and execute code in python, we first need to install Python on our system.Installing Python on Windows takes a series of few easy steps.Step 1 − Select Version of Python to InstallPython has various versions available with differences between the syntax and working of different versions of the language. We need to choose the version which we want to use or need. There are different versions of Python 2 and Python 3 available.Step 2 − Download Python Executable InstallerOn the web browser, in the official site of python (www.python.org), move ... Read More

In this article, we will create a GUI-based dictionary using PyDictionary and Tkinter Module.PyDictionary is a Python Module that helps to get meaning translations, antonyms and synonyms of words. It uses WordNet for getting meanings, Google for translations, and synonym.com for getting synonyms and antonyms. PyDictionary uses BeautifulSoup, Requests module as the dependencies.In order to create the application, we will first install these modules in our environment using pip install PyDictionaryAfter installing, we will create a tkinter frame and some other element.Example# Import Required Librares from tkinter import * from PyDictionary import PyDictionary # Create instances and objests dictionary ...

In this article, we will create a GUI-based window resizer control panel that will have a pane to resize the window by its height or width.In order to create the application, we will first create a slider that will help to resize the window size. The sliders are available in the ttk library of tkinter. We will import “ttk” first. Then, we will launch a new window which needs to be resized.Let us first import all the required libraries in the notebook and design the control bars using sliders.Example# Import the required Libraries from tkinter import * from tkinter import ...

Using Tkinter.Menu, we can create menus and submenus. Also, there are some other properties which are used with tkinter menus.Tearoff property makes the menus in the window as tearable. tearoff attribute accepts a Boolean value to separate the menu from the main window or the parent window. With tearoff attribute, we have two options, If tearoff=0, make the menu stick to the Window.If tearoff=1, it display a “----” empty dotted lines on the menus through which we can separate our menu from the window.Example#Importing the tkinter library from tkinter import * win= Tk() win.title("Tearoff Example") win.geometry("600x500") #Define a Function ...

Tkinter bell() method produces the default event or dialogue sound of the system. This method can be invoked in the default window or frame. We can change the sound of the window by going to the system configuration.In this example, we will create a button that will make the default sound.Example#Import the library from tkinter import * #Create an instance of tkinter frame win= Tk() #Define the size of the window win.geometry("700x150") win.resizable(0, 0) #Define the Bell function def click():    win.bell() Button(win, text= "Click Me", command= click).pack(pady=20) win.mainloop()OutputRunning the above code will create ...

In this article, we will see how to create a functional application that calculates the ratio. In order to make it fully functional, we will use SpinBox method that generally creates an ideal spinner for a value. This value can be modified using the spinner widget in the frame. Thus, a SpinBox object takes values in the range from minimum to maximum.First, we will create a tkinter frame inside which we will define some widgets.Examplefrom tkinter import * win = Tk() win.title("Ratio Calculator") win.geometry("600x500") win.resizable(0, 0) #Create text Label for Ratio Calculator label= Label(win, text="Ratio Calculator", font=('Times New ...

Let us consider that we have a value x and we have to calculate the sum of sine(x) series. In a sine(x) series, there are multiple terms such that, sine(x) = x− x^3/fact(3) + x^5/fact(5) −x^7/fact(7)....In order to solve the particular series-based problem, we will first take the degree as the input and convert it into radian. To find out the sum of the total number of terms in this series, we will first iterate over all the given terms and find out the sum by operations.Approach to solve this ProblemTake input of Limit and degree.Iterate over the terms and ...

Let us suppose that we have a string and we have to calculate the total number of digits and letters present in the string.For ExampleInput −s = “tutorialsP0int”Output −Letters: 13 Digits: 1Explanation −Total number of letters and digits present in the given string are 13 and 1.Approach to Solve this ProblemTo calculate the total number of letters and digits in the given string, we have to first iterate over the whole string. If we get an alphabet, then we increment the letter count; otherwise, if we extract a digit, then increment the digit count.Take an input string.While iterating over the whole string, ... Read More
