Hello,

I have created an interface with buttons and comboBoxes and I want to change the value of DATA [1] which is in the send.py file every time I press a button, it assigns it the new value of DAT1.

I have defined the functions of BTN1, BTN2, BTN3 for the push buttons

I want to have an idea how to code to have the desired result





here is the code of my 2 file Python
