ANSWER
Answered 2021-Mar-13 at 18:44I have re-written your code because there were two issues:
- There's no such thing as
print(input("")) flag = input("Do you want to calculate more(y/n)? : ")should be outside else
QUESTION
Hopefully I am following the guidelines correctly here with my first question. I am trying to create a GUI with the MVC structure. I am having difficulty with understanding why my signals are not always being picked up by the controller. I know that there is just something simple that I'm missing. I'm attaching code from a simple calculator which I used as a guide. I removed most of the features to simplify this as much as possible. It is now only 3 of the original buttons and my own button. For debugging, I just have the value on the button printed out when you press it.

Answered 2020-Nov-19 at 17:31The problem is caused because the PyCalcCtrl object is not assigned to a variable so it will be destroyed and therefore the "_printthis" method will not be accessible. On the other hand, when functools.partial is used then the object of the PyCalcCtrl class is assigned to the scope of that function, that's why it works.
The solution is to assign the PyCalcCtrl object to a variable:

I am trying to build a simple GUI using PyQT5, with 3 buttons to open file browsers and one more to run processing with the selected files, but I can't get my buttons to connect to the functions needed to carry this out.
In the Ctrl class, the _connect_signals function doesn't seem to be calling _input_select. Can anyone help me figure out why?
ANSWER
Answered 2020-Sep-30 at 18:09The problem is that you are not keeping any persistent reference to the Ctrl() instance you are creating. This results in python garbage collecting it as soon as the instance is created.
To solve the issue, just assign it to a variable:
QUESTION
I've just started learning python's tkinter module today. I'm making a basic calculator for practice. Currently I'm just making the actual GUI for it and the '0' button has margin on each side of it and I'm unsure why. Like I said, I just started learning it today. Can someone tell me why this is happening and also how to make it not?
Here is what it looks like:
Looking at the 0, there is margin on the left and right of the button.
Here is the code:

Install pyCalc
You can use pyCalc like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
