How to Program a GUI Application (with Python Tkinter)!

Learn data skills with hands-on exercises & tutorials at Datacamp!

In this video, we learn how to build an application with a graphical user interface (GUI). This is a great video to learn how to use the Tkinter library as well as be introduced to some very important Python skills.

We start off by introducing the fundamentals of the Tkinter library. We then create a frame for a weather application. We then connect it to a weather API and then finally convert the application to an executable file.

Finally, i programming tutuorial from someone with a sense of humor and a voice thats louder than 2db, and the tutorial is really understandable

[charlietame]

Definitely the best tutorial yet. I'm not exactly a novice but the fact that you took your time explaining "Why" you chose to do things a certain way was for sure something missing from other tutorials and will help a lot of people.

I'm a 66 yr old and was not going to try learning python; but this video got me interested and running down the rabbit hole. Nicely Done!

[ivanllopis]

This is the best video on Tkinter I've ever seen. Thank you so much, I'm definitely sharing this one with whomever may find this useful. Good work!

[ArtuursPaulausks]

It is much easier to understand when a person explains syntax in his own words. Awesome video, thanks !

[ActuallyAudacity]

For people trying to this program while following him along, if you're not using sublime text you may have problems with the request function. In order for it to work go on command prompt and type "pip install requests" and then go to your code and "import requests".


Hope this helped if you were stuck on this!

This was the second video of yours I’ve watched and I’ll be watching more. You speak *naturally* - you’re not reading from a script or mumbling; it’s like I’ve just sat down with you and you’re showing me something. Also, when stuff doesn’t happen just right the first time - that’s VERY real life - you’re modeling what to do - don’t panic just go back over stuff and figure out what you did wrong. Easy-peasy! I love this style of teaching, thanks.

[direndeniz]

He is teaching us by learning simultaneously which makes the video more natural. That's why I subscribed to him... Great job Keith. Keep going. Greetings from Turkey...

[TheKhashix]

You're a wonderful teacher. Only just getting started in Python and you manage to make all the concepts incredibly easy to understand. Not only that, you're always going in and explaining why you're doing something, providing a real kick-start to the learning process. Thank you for uploading this!

[AspartameBoy]

The documentation "out there" is not very effective. Your video is super.

[justinmcdonald]

If you'll getting a syntax error with the "Lambda:" code, try using lowercase L in "lambda:"

[maniac]

What makes this tutorial better than any other tutorials on tkinter I have seen is, that you import the module as tk and not as * so that one can distinguish the tk calls from all the other stuff at first sight. You also don´t put everything in a class like many tutorials out there which only complicates things.
I haven´t seen anyone else describe the place-function - which is a great tool to make the gui look professional.

[patrickmbarker]

Thanks Keith, I learned a lot in this one. I started learning programming with Java in college, but I am finding Python much more fun to work with. I've finally got that motivation back for programming.

[Phoenix-tono]

I realise this is literally a year after you posted it but it is still the best source I've found for learning how to use Tkinter. Thanks :)

[maximilianschmid]

If you have problems loading the pic on a mac, try importing: from pathlib import Path
then define the image path: image = Path('*your folder1*/*your folder2*/*your folder3*/*your_pic.png*')
After that just add file=image: background_image = tk.PhotoImage(file=image)

Thanks for the vid, Keith!

[AlbertLeng]

I had a hard time reading the "official" documentation as I guess it's not really well-maintained and updated. Following your video is such an efficient and effective way to kick start my Tkinter learning. Good job brother!

[theheadpriest]

youcould change the title from tk to weather app with root.title('Wheather App') :D

[VarunSridharan]

This i can guarantee is the fastest and clearest way to learn the basics of interactive GUI python programming and API calls. Beautifully done tutorial! Many thanks, God Bless.

[baksagimm]

Best tk tutorial out there! Thankyou. I was struggling with overcomplicated official docs.
