Build a Working Calculator App in Python with Flet #python #coding #programming This video walks through building a functional calculator app using Python and the Flet UI framework. You'll see how a single button_click function handles every button press, using a data attribute to identify which key was tapped. The code shows how input is appended to a text display, how the clear button resets it, and how the equals button uses Python's eval to compute the result. It also covers a helper function that generates all the calculator buttons without repetitive code, and how the layout is organized into rows for numbers and operators. By the end, you'll have a real, clickable calculator built in pure Python.
