Continue Building A Simple Calculator App - Python Tkinter GUI Tutorial #6

Let's Continue Building A Simple Calculator App. In this video we'll continue to build out our simple calculator app using the stuff we've learned from the previous videos. We'll create the clear button, the add button, and the equal to button functionality in this video.

In this series I'll show you how to create graphical user interfaces for Python with Tkinter. TKinter comes with Python already, so there's nothing to install!

You're genuine. This is how we code, making mistakes, hoping it runs, too many edited videos making the programmer look perfect, no syntax errors, never a question on how an API works. This should inspire aspiring programmers. Thanks.

"I'm just making this up as I go, you can tell." Made me laugh. Thank you for the video series this is very helpful and fun!

1:10 On the 13th line you could write 'END' insead of 0 and it'll be working.

Great video, this came in handy for my college project which requires python and Tkinter. Even my college tutor makes many mistakes in his program.

Hello from Brazil. I decided to learn some python, and I realized that the best way to learn something is use this something in a project. So I opened 10 youtube videos on "how to make a simple calculator with python", and after watching one of you videos I closed all the others. The way you explain things is very interesting, thanks for the amazing tutorials.

This is the best library introduction series of all time, seriously. The way you present and show things allows us to not only understand it, but to be able to create and implement into our own ideas immediately. Cannot thank you enough for your videos.

The best tkinter Tutorial in the youtube.

A really simple way of fixing the calculator number input issue is to change "e.insert(0, number)" to "e.insert(END, number)". This eliminates the need for a "current" variable and the string concatenation

[kameenabandar]

We can also create a variable i and pass it in e.insert(i, number) and increment it each time for correct representation

Then while clearing reset the value of i to 0
This worked pretty well

I can't believe that I have 170 more amazing videos to watch!

To how want's to learn python easy this good chanel لكل من يريد تعلم بايتون هذه القناة افضلل مكان للتعلم.
شكرا كثيرا thanks lot

[marcmathieutrance]

I like your reaction when your code runs! lol

Best web series I am watching right now

[hardikpunj]

We may write
a=e.get()
e.insert(len(a), num)

[andrejvujic]

You could've used the inbuilt string split method for adding numbers, btw thanks for the great tutorial series

[umpalumpa]

Would be interesting which other ideas you guys came up with for doing the math. Maybe we can collect them in this thread.
I used a little different approach and used result = eval(e.get()) for the equal button. The advantage is, that we can see the calculation all the time. Furthermore we can type in a calculation into the text field (which is of course not the aim of this video).

Why we should use lambda to execute the command
