To obtain a user's IP address, we can use Python's native networking interface, socket. First of all, we need to query the device's host name and then get its associated IP address.In this example, we will use the socket library to get the host name and IP address and print the details on two labels.Steps −Import the tkinter library and create an instance of tkinter frame.Set the size of the frame using geometry method.Next, use the gethostname() method of socket library to get the host name and store it in a variable "hostname".Then use the gethostbyname() method and pass the ...

To draw a dashed line on a Tkinter canvas, we can use the dash parameter of create_line() method.Steps −Import the tkinter library and create an instance of tkinter frame.Set the size of the frame using geometry method.Create a Canvas widget and set its height and width.Next, use the create_line function and pass the coordinates of the line (x1, y1) and (x2, y2).To get a dashed line, use the dash parameter dash=(5, 1) for 5px dash followed by 1px space.You can set the color and width of the dashed lines using the fill and width parameters.Finally, run the mainloop of the ...

To align the checkbuttons to left, you can use the anchor parameter and set it to "w" (west). Let's take an example and see how to do it.Steps −Import the tkinter library and create an instance of tkinter frame.Set the size of the frame using geometry method.Create a LabelFrame to collect the checkbuttons in a group.Next, create a checkbutton inside the LabelFrame and set its anchor to the West. anchor='w'.Similarly, create three more checkbuttons with their anchor set at West. It will align all the checkbuttons to the left.Finally, run the mainloop of the application window.Examplefrom tkinter import * ... Read More
Given a number n, we have to find the number of integers with an odd number of set bits in their binary form. Let's see an example.Inputn = 10Output5There are 5 integers from 1 to 10 with odd number of set bits in their binary form.AlgorithmInitialise the number N.Write a function to count the number of set bits in binary form.Initialise the count to 0.Write a loop that iterates from 1 to N.Count the set bits of each integer.Increment the count if the set bits count is odd.Return the count.ImplementationFollowing is the implementation of the above algorithm in C++#include ...

To exit from Python using a Tkinter button, you can follow the steps given below −Steps −Import the tkinter library and create an instance of tkinter frame.Set the size of the frame using geometry method.Define a function close() to close the window. Call the method win.destroy() inside close().Next, create a button and call the close() function.Finally, run the mainloop of the application window.Example# Import the library from tkinter import * # Create an instance of window win = Tk() # Set the geometry of the window win.geometry("700x350") # Title of the window win.title("Click the Button to Close ...

To display the current date in tkinter window, we will use the datetime library.date = dt.datetime.now()Steps −Import the required libraries and create an instance of tkinter frame.Set the size of the frame using geometry method.Call datetime.now() and store the value in a variable "date".Next, create a label to display the date. In the text parameter of the label, pass the date value and format the data as text=f"{date:%A, %B %d, %Y}".%A – Day of the week, full name%B – Full month name%d – Day of the month%Y – Year with century as a decimal numberFinally, run the mainloop of the ...

You are given an array, and indexes range. You need to count the total number of adjacent elements that are equal in the given range.Let's see an example.Inputarr = [1, 2, 2, 2, 3, 3, 4] lower = 1 upper = 5Output3AlgorithmInitialise the array and indexes range.Write a loop that iterates from the lower index of the range to upper index of the range.Compare the element the previous or next element.Increment the count if they are equal.Return the count.ImplementationFollowing is the implementation of the above algorithm in C++#include using namespace std; int getEqualElementsCount(int arr[], int n, int lower, int ...

To display multiple labels in one line with Python Tkinter, we can use the pack() method of label and align all the labels to the same side. Let's take an example and see how to display multiple labels in one line.Steps −Import the required libraries and create an instance of tkinter frame.Set the size of the frame using geometry method.Create a label and name it "Label 1". Set its font and highlight the label with a background color.Next, use the pack() method of label and set side=LEFT to force the label to position itself on the left of the screen.Similarly, ...

There are two different ways in which we can get an automatically maximized window in Tkinter.We can use the state() method of Tkinter and invoke it with the attribute "zoomed".root.state("zoomed")The second approach is to use the attributes method of Tkinter with the parameter "-fullscreen" and set it to True.By default, Tkinter creates a window of a predefined size. The dimensions of the window can be customized using the geometry method. For example, root.geometry("700 x 350") Example 1# Import the required libraries from tkinter import * # Create an instance of tkinter frame root=Tk() # Create a label Label(root, ... Read More
The create_text method of Canvas widget in Tkinter doesn't have an attribute like "outline" or "border" to set an outline around a text object. So, to put an outline on a canvas text, you can follow the steps given below −Steps −Import the required libraries and create an instance of tkinter frame.Set the size of the frame using root.geometry method.Create a Canvas widget and set its height and width. Also, set its background color with background="white".Next, create a text object inside the Canvas using create_text() method. Set the font and color of the text as shown in the example.Get the ...
