Tkinter-How to get the current date to display in a tkinter window?
Tkinter is a popular Python library that is used to create graphical user interfaces (GUIs). It comes bundled with Python, which makes it a convenient choice for developers who want to create a GUI for their applications. One common use case for Tkinter is to display the current date in a tkinter window. In this article, we will explore how to get the current date and display it in a tkinter window.
Step 1: Importing necessary libraries
Initially, we need to import the necessary modules to use the functionalities required in our code. Here, we will be importing the tkinter module to create the GUI window and the datetime class from the datetime module to get the current date.
import tkinter as tk
from datetime import datetime
Step 2: Creating the tkinter window
In this step, we will create a new tkinter window, set the window’s attributes such as its title, size, etc.
window = tk.Tk()
window.title("Displaying Today's date")
window.geometry("200x50")
Step 3: Defining the function to display the date
In this step, we will define a function that retrieves the current date and displays it in the tkinter window. Inside the function, we will first get the current date using the datetime.now()
method and then format it using the strftime()
method. We will then create a label widget and set its text to the formatted date string.
def show_date():
today = datetime.now().strftime("%d-%m-%Y")
date_label = tk.Label(window, text="Today's date is " + today)
date_label.pack()
Step 4: Adding a button to display the date
In this step, we will add a button to the tkinter window that will trigger the show_date()
function when clicked. We will create a new button widget using the tk.Button()
method and then set its text and command attributes.
date_button = tk.Button(window, text="Show today's date", command=show_date)
date_button.pack()
Step 5: Running the tkinter application
Now that we have defined all the required components, we can start the main loop by calling the mainloop()
method.
window.mainloop()
Final Code
Putting it all together, the final code to get the current date and display it in a tkinter window would look like:
import tkinter as tk
from datetime import datetime
window = tk.Tk()
window.title("Displaying Today's date")
window.geometry("200x50")
def show_date():
today = datetime.now().strftime("%d-%m-%Y")
date_label = tk.Label(window, text="Today's date is " + today)
date_label.pack()
date_button = tk.Button(window, text="Show today's date", command=show_date)
date_button.pack()
window.mainloop()
You can run this code to see the current date displayed in a tkinter window.
Conclusion
In this article, we learned how to get the current date and display it in a tkinter window using Python. We started by importing the necessary modules, creating the tkinter window, defining a function to display the date, adding a button to trigger the function, and finally running the tkinter application. With this knowledge, you can now easily display the current date in your tkinter applications.
