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

[@matheusjanczkowski9107]

And is not speaking fucking broken English with Indian accent...

[@nikothenoob]

first reply?

[@charlietame1892]

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.

[@jdsguam]

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!

[@truepenny2514]

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.

[@ivanllopis5882]

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!

[@KeithGalli]

Glad you enjoyed, and thanks :)

[@moletsanephillipmakhate5305]

I also agree with this sentiment

[@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!

[@Redagrandrei]

Thanks man

[@Stellarspace95]

dang, I read your comment and when I ran into the issue I remembered you posted this so thanks lol

@@Stellarspace95 No problem :D Glad it helped some people out because I had this problem as well and was very confused

[@lokeshkumarw9045]

why did people have this problem? He mentions in the video about installing "requests" and then imports it as well!! :/ Edit: installs at 2:30 imports at 44:00

@@lokeshkumarw9045 Could you put the time please? I may have missed it.

[@AspartameBoy]

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

[@maniac1814]

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.

[@direndeniz8817]

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...

[@maximilianschmid2644]

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!

[@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!

[@justinmcdonald1930]

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

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 :)

[@KeithGalli]

Well I still usually see the comments :). Glad you enjoyed!!

[@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!

[@Nunya58294]

One of the best tutorials I've seen for this.This also helped me understand frames a lot more with a visual rather than just explaining

[@joeythompson2375]

Thank you, Very thoughtful of the viewer. Hat tip to you sir on tutorials point. wow a goldmine. I appreciate the honesty in showing that a huge part of this is looking up things. When I started watching coding videos , I was scared I would need to memorize an encyclopedia. Big confidence boost here.

Thanks for the video , keep up the good work bro.

[@VainerCactus0]

Thanks for this. Was my first time coding anything using the requests module, so it was very helpful.

[@lilystar5]

VainerCactus 0 my import requests doesn’t work, it says “there’s no module named ‘requests’

[@VainerCactus0]

@@lilystar5 You know when you import random or import tkinter? import requests is the same, except requests does not come with the standard python instal. You need to download it off the internet. There should be some command for that, but it is too early for me to remember that. Just google pip instal requests and see what you come up with. There are a whole bunch of libraries and modules you can download from the internet.

[@SS-bb1nc]

Thanks for actually explaining the positioning methods. Strange, but I dont think any of the tkinter tutorials I watched before even mentioned place(), and its the most useful in my opinion. Best tutorial I've watched so far. You deff got a new subscriber

[@MmmBopsPops]

Never knew why lambdas were needed in JS as well for setTimeouts and stuff, but now it makes sense. Thanks!

[@purple_rhino]

If your getting Pillow doesn't works properly, you might want to reinstall python, making sure that when you reinstall, you check the box that says 'Copy to path' or something along those lines. Helpfully saves a lot of frustration.

[@chrisw5509]

Fantastic video! I am a beginner programmer, lol - more like a “wanna be” programmer. I started with Python and the related GUI Kivy. Your video enabled me to get a grasp on using API with Python. However, I was challenged by translating your Tkinter GUI into Kivy. I succeeded and created a Kivy Weather App. In connection, I only used one Python function / method. For my purposes and limited experience, I found using one function preferable. I have subscribed and intend to view more of your videos. Please keep up your efforts. I really appreciate your videos!!

What is that screen you left up at the end of your video (the one where you were PIP things into? I'm using Windows. Great video and I enjoyed your thorough explanations and the why you did things. A lot of other tutorial videos seem to lack the why, they seem more interested in just showing the how. Keep up the great work. My only suggestion is to create a list of your videos (in order from start to the latest). Just starting out in Python and "stumbled upon this video as a "suggested video" by KZbin. Really enjoyed it. Thank you.

By the way instead of a Lambda the "Entry" fields can be read by a function as long as the function is defined after the entry fields. I didn't want to complete the weather program but here is a snippet that works. This had me fooled for a time until I realized what I was missing :) import tkinter as tk import requests from PIL import Image,ImageTk root = tk.Tk() HEIGHT = 500 WIDTH = 600 canvas = tk.Canvas(root, height=HEIGHT, width = WIDTH) canvas.pack() background_image = tk.PhotoImage(file='bgnd.png') background_label = tk.Label(root, image=background_image) background_label.place(relwidth=1, relheight=1) frame = tk.Frame(root, bg='#80c1ff', bd=5) frame.place(relx=0.5, rely=0.1, relwidth=0.75, relheight=0.1, anchor='n') entry = tk.Entry(frame, font=40) entry.place(relwidth=0.65, relheight=1) button = tk.Button(frame, text='Get Weather', font=40, command=get_weather) button.place(relx=0.7, relheight=1, relwidth=0.3) lower_frame = tk.Frame(root, bg='#80c1ff', bd=10) lower_frame.place(relx=0.5, rely=0.25, relwidth=0.75, relheight=0.6, anchor='n') label = tk.Label(lower_frame, text='This is a label', bg='yellow') label.place(relwidth=1, relheight=1) def get_weather(entry): weather=(entry.get()) print('Weather', weather) root.mainloop()

[@vaelinalsorna1649]

Thanks for the tutorial. I have been learning tkinter from other yoututbers and have read the docs but couldn't find a solution to make sure my widgets resized when you mess around with the window. Searched stack overflow and the official tk docs that recommended using grid_propagate(0) then adding 2 arguments (arg, weight=1) to rowconfigure and columnconfigure with weight being the supposed solution to my problem. Well, it didn't work. :/ Thankfully, I stumbled upon your video explaining how place() works instead of using pack() and grid(). Really appreciate the video. Keep up the great work.

[@Medhusalem]

Hey mate, really great Tutorial. I have but two questions. (Didn't finish yet I am at 38:42). First: Why do we need a canvas, when we put all our frames into root as well, can't we just use the frames for canvas or ignore canvas all together? frame1 = tk.Frame(canvas...) frame2 = tk.Frame(canvas...) or frame1 = tk.Frame(root...) frame2 = tk.Frame(root...) This confuses me a little bit. Second: What about the button click, what do you think about doing it this way: def test_function(): print("Entered: "+ name.get()) name = tk.StringVar() entry = tk.Entry(upper_frame, font = 40, textvariable = name) This way we would also get the text inside the Entry. Do you think it is just perference or is your method a better, more standard way in doing it? Kind regards
