[@BrendanBurkartSF]

this was super helpful and really well done! I actually really liked that you had the lambda still in there for the btn_equals...it let us see your debugging process. Thank you!

[@wko_]

Very simple and very useful! Thanks for one more project like this!

[@nipoteemus2472]

Thanks for the tutorial! I have that kind of school project where I have to make a representation of your favorite hobby or that stuff! I planned to make it about coding and I'm trying to do 3 softwares for it and this is fricking good idea!

[@thatgarryman9400]

Literally explained better than half of the programmers in KZbin. Makes sense, explains, doesn't do unnecessary stuff.

[@efogovirtual9635]

I appreciate you, this is absolutely useful, nice tutorial

Nice. Do you think I can include this in my portfolio to apply for a job? I can say that I followed your tutorial and learned from it.

[@dieelitezwerge7622]

thanks for another very nice video😇😉

[@lerserk]

19:46 Its the lambda bro!! Thank you for this!

[@sithhill]

How does this do the actual math portion without telling it to do a math calculation? The other calculator I made doesn't have a GUI but all the code is to specify the actual math method being used versus, all we (you) did was create buttons. I followed along and just don't understand how it's automatically doing the math.

the best tutorial ever bro u da best

[@rezalapriani1001]

i learn from your video, thanks you soo much

[@patibandlalatha7530]

Very much helpful to the python learners

[@brendanjordan5485]

Thank you for the video! If I want to make it so that I don't have to type a '*' before the parenthesis for the code to recognize that it should multiply, how do I make it so that this code recognizes that 'x(a)", where x and a are any number , are suppose to multiply? Like if I want it to calculate "90/3(1+2)"

[@jeez8136]

i was wondering that too so i asked chatgpt and this is what it said: To make the code recognize this implicit multiplication, you can add a check in the add_to_calculation function to see if the last symbol in the calculation string is a number, and if so, add the multiplication symbol before adding the parentheses. Here is an updated add_to_calculation function that implements this logic: def add_to_calculation(symbol): global calculation if symbol == "(" and calculation != "" and calculation[-1].isdigit(): calculation += "*" calculation += str(symbol) text_result.delete(1.0, "end") text_result.insert(1.0, calculation) With this code, if the user types a number followed by an opening parenthesis, the function will automatically insert a multiplication symbol before the parenthesis. This means that if the user types "90/3(1+2)", the calculation string will become "90/3*(1+2)" before evaluation.

[@TheRealStrider]

@@jeez8136 So I was wondering this as well and have finally made it work behind the scenes without it showing it add the * before the (. Here is the code: implicit = list(calculation) i = 0 while i

[@oadeep]

thank you so much it works@@TheRealStrider

[@rushikeshmali3057]

Thanks for beautiful guidens

[@surfineer]

Interesting explanation on the eval() functionality. But what alternatives would you suggest for better security?

[@GeovaniLopesDias]

I didn't watched it with audio on, so I don't know what security issues he mentioned, but I was wondering the whole video when would he write the regex code to interpret the string arithmetic expression. It'd require some extra functions to substitute the eval() built-in. For personal challenge, we could try to code these said extra functions.

[@skystep2]

I am noob, but I would not allowed letters, only go execute eval if there are no letters and other not allowed symbols

[@v11r]

You need to implement a tree

[@akellner2]

Thank you for sharing, I wonder how I can implement an %-Button with the correct function. I tried it but I can`t figure it out.

is it possible to make a delete button? If so how do you do it, cos i have been trying to figure it out for the past week, but still can’t (i’m a beginner btw）

[@alirezaahmadivand831]

Thanks a lot 🙏

[@piklif5278]

this helped me so mauch thax

[@aradthetyper2101]

brilliant! just one thing. i don't get the part where you put (1.0, "end") after text_result.delete or text_result.insert. what do they mean?

[@poorvinalavade8651]

even i want to know the meaning of those parameters

[@timmyt1232]

In tkinter (for text), delete(first index position, last index position). The 1 is first line. The 0 is before first character. The "end" is to the end of the text. insert(index position, string)

[@Himlajchan]

@@timmyt1232 Would you mind explaining where this 'end' argument is defined? Tried to look into the source via PyCharm, but couldn't find where this is specified, not even in any documentation that I looked trough. How can I know what other strings are valid for the index parameter?

[@housemajaliwa]

Good stuff

[@Victory-py7lp]

Can someone explain why he uses the .delete first before the .insert? What does that do?

thank you very much

everything worked but the buttons only work individually instead of 1+2 it would just say the number by itself when clicked instead of holding memory. any tips or advice

i have tried installing this Tkinter but still wouldnt work on my window 10 or my mac pro. its so confusing i get this error : "ModuleNotFoundError: No module named '_tkinter'" what do i do

You needed 2 minutes to figure out the problem but you still didn't figure it but got another solution but my solution was after 2 secs after I saw the code and it is to put brackets after evaluate_calculation and it worked with me 😅

so usefull and hepfull I subsribed this is my 2nd videio watching

i have also a function if you want to remove one character from the calculation if you made an error typing, but you need an extra delete button for it: def remove(): global calculation if calculation: calculation = calculation[:-1] text_result.delete(1.0, "end") text_result.insert(1.0, calculation) pass pass
